Thanks for the valuable suggestion.

This seems more like adding the sequence support which we’re seriously considering for the next major release.

Meanwhile, would using identity column help?

<=-=Feb 2 2008 2:11AM=-=>

It does not seem that you understood the request. This definitely has nothing to do with
IDENTITY. I am less versed about sequences, but I don’t think they will cut it either. If you think
it does, maybe you could provide an example? Take this problem: For the Orders table in
Northwind, write a query that lists the number of orders for all days in 1997. The result set should
include all 365 days, and list zero for days without a number.

This is a typical problem where you need a table of of numbers (or dates). While it’s easy to
create such a table, I argue in this request that there would be a number of advantages of
having such a table (function) builtin. For more details on the optimization problems, see my
article on Arrays and Lists in SQL Server, http://www.sommarskog.se/arrays-in-sql.html.

<=-=Feb 27 2008 11:40AM=-=>

Where do you stop with the content of the numbers table?

1-100? 1-1000000? What if I need 10billion? What if I need numbers up 2^64?? More?

Seems like an awful waste of space for something that may or may not be used.

As per workaround, use a function. (would be nice if that function was built-in..maybe that’s what they mean by ‘sequence’?)

<=-=Jul 3 2008 6:11AM=-=>

I would say 100000 by default
Another option would be if that 100000 is not good enough for you there would be a built in proc that will generate this table for you, you would have to pass in the start and end value and the proc would generate this table

<=-=Jul 3 2008 8:58AM=-=>

This would be a great asset and I believe it to be worth the storage requirement. 100,000 is a good number to default to and if more numbers are needed; I am sure some sort of system sp that builds the table dynamically. The bottom line is a lot of people are not acclimated with the concept of a numbers table and are missing out of all the performance gains from using one. Having MS built-in numbers table not only exposes the numbers table, but also allows those who do not want to manage an additional table to reap the benefits.

<=-=Jul 7 2008 5:11AM=-=>

Adding a built in table of numbers from 1 to 2 billion would certainly take up a lot of disk space especially if you consider the fact that most people never use one with a count over 8000 and those that do almost never use one over a million.

What I’d rather see is a whole number “sequence generator” where you could identify the StartValue, EndValue, and optional Increment which would default to 1. And, it should be able to order the values in an ascending or descending fashion as if it had a Clustered Primary Key doing so.

<=-=Jul 15 2008 9:59AM=-=>

Why would anything need to be stored on disk? Make the query engine intelligently produce the numbers on demand. It would be an in-memory operation, perhaps not even needing all rows to be materialized, as in the case of splitting a string on a delimiter where the majority of the numbers are discarded.

The optimizer could pay attention to how the numbers are used and do an in-memory loop through the string rather than creating a table, temp or otherwise. The table is uniform and regular, and re-generating it each time in a tight +1 loop is probably faster than building the whole thing. It’s like a kind of native index where you know in advance where everything is because the lookup index is exactly equal to the lookup value.

Look at it this way. What would the query engine have to do to satisfy this query:

SELECT Num FROM Numbers WHERE Num = 123

It wouldn’t have to hit the Numbers table at all: the input IS the result. The answer can be given at parse time. Similarly,

SELECT Num FROM Numbers WHERE Num BETWEEN 1 AND 100000

Again, why hit the table at all? It already knows the desired result, the numbers 1- 100000. It would be far more efficient to just generate the values in memory than go read them somewhere. (give me 1st value: okay, got 1. Give me 2nd value, okay, got 2. …)

Many problems are easily solvable with a numbers table that are difficult or impossible otherwise.

<=-=Aug 5 2008 12:58PM=-=>

Indeed, the table would only be logical, it would not be stored on disk.

<=-=Nov 25 2010 11:53PM=-=>

A little bit off-topic, but could I also get the same thing for dates? It just seems so stupid to create table that has dates so that you can join it with other tables to get one row for each day even if data doesn’t exist for that day.

<=-=Dec 14 2010 2:54PM=-=>

Please read feedback id 347442. Such a built-in function would have (potentially) significant performance impacts, lacking in user defined functions/solutions (mentioned feedback id has examples).

<=-=Jan 1 2011 6:00PM=-=>

Glad to see this suggestion. This functionality would help with many of the perennial problems that come up on news groups and forums.

<=-=Mar 14 2012 4:17PM=-=>

I see Postgres has the “generate_series” function for this need.

<=-=Jun 11 2012 1:19PM=-=>

Neither identity nor sequence will help here. It is hard to believe you even read the question.

Having had the “joy” of splitting a multi-XML-document proprietary 3rd-party supplied file of over 3MB, my Numbers table was 12M+ rows, just in case a heavy ordering day bumped the file size…

On SQL2012, using page-level compression, it consumes over 130MB.

If, as current best practices appear to recommend, our SQL Servers are stacked with huge quantities of RAM, 130MB in, say 120GB isn’t going to matter a great deal…

If Microsoft gave us a “standard set” of Numbers that is configurable, but which could be bumped on demand and shrunken automatically to the standard-set-size, memory pressure would be reduced while still delivering high-speed data-access.

My Dates table stretches from 2008 (birth of system) to 2099, comprising 33K rows of 32 columns (at present) and 16MB compressed, with alternate indexes. Again, a triflingly small memory “hog”.

I’m less persuaded that a Microsoft-supplied Dates table is a “need” simply because the slices and representations of dates in short/long/week/month/quarter, etc. are really site-specific (hence my 32 columns!).

+1 for the Numbers table…

Please, please, please.

Howdy there, Microsoft,

This suggestion is going to be 8 years old in 3 months. It would be wonderful to celebrate that anniversary with a CU for both 2012 and 2014 that contains this wonderful suggested tool. It shouldn’t take you long.

I’ll also suggest that it take two parameters so that folks can start it “0” if they need to (which is more common than you’d think).

Thank you for your time.

<=-=Nov 26 2014 4:42AM=-=>

Personally, I think this relatively simple addition is long overdue. The Tally table has been called the Swiss Army Knife of SQL and I have to agree. It can be used for everything from splitting strings to date generation. An ITVF that’s built into the product would allow for optimization that’s probably beyond what DBAs can do. I’ve been using a table of numbers for years and consider it completely normal, as do many others in the SQL Server community. Please consider the addition of this feature to the product.

<=-=Nov 26 2014 6:31AM=-=>

This would be handy even if it it were no larger than a single record and additional functionality were added to SQL Server such as “Connect BY” and so forth to allow for larger virtual numbers tables could be accessed. Many uses are out there for such a table and if there is any doubt, take a look at the DUAL table in Oracle.

<=-=Dec 1 2014 7:55AM=-=>

This is fairly trivial to develop, but also the issues raised above (integrity) are potentially a problem in app code. Think SQL Injection or some other tampering that wouldn’t be the case in a native numbers table.

While this would be a nice backport, I would argue this is fairly minor work for SQL Server 2014+ (in an SP) and giving us a table with an integer’s worth of numbers, would be very handy. I would suggest that the table be a DMV visible in every database.

The easiest trick to generate table of numbers with OPENJSON:

create function
dbo.fn_gen_numbers(count int) returns table return (select cast([key] as int) as number from OPENJSON( '[1' + replicate(',1',count-1)+’]’))

You will need SQL Server 2016 CTP3 or higher for this.

<=-=Mar 5 2016 8:30AM=-=>

This should not be a real table with a fixed number of rows. This should be a generator TVP that can provide any number range, e.g.

select Number from Builtin_Numbers(1, 10000000)

It would be a pity if the built in numbers table would be restricted to some range, e.g. [1, 1M].

We also need such a generator for dates (all dates in a given range).

I definitely see the value of this. Thanks for proposing it. We’ll try to squeeze it in to SQL Server 2008 but things are really tight in terms of room for changes like this. It has to compete with many other things, including a bunch that have a larger impact on query performance, or that don’t have an easy workaround. This issue has a workaround, though it is not pretty and programmability would be enhanced a lot with the proposed enhancement. I’ll see what I can do.

Best regards,
Eric

<=-=Oct 17 2007 2:06PM=-=>

Things do not look good for this enhancement for Katmai. It probably will not make it into the release. We’ll make a final assessment in a couple of weeks. Before we can consider this, we have to finish other commitments.

It’s not just the aesthetics of the code at stake here, it’s performance. The workarounds involve either OR statements or the ISNULL function, both of which de-optimize queries in profound ways.

Hello

Thank you for your feedback. We’re certainly considering row value constructors for a future release of SQL Server.

- Sara Tahir
Microsoft SQL Server

<=-=Aug 11 2010 8:03AM=-=>

I think row constructors would be a great and important addition to T-SQL. Just wanted to point out a few more cases that I’d love to see implemented:

---

- Assignment
-—————————————————————————————————-

UPDATE dbo.T1
SET (c1, c2, c3) = (@p1, @p2, @p3)
WHERE keycol = @key;

— Logically equivalent to:

UPDATE dbo.T1
SET c1 = @p1,
c2 = @p2,
c3 = @p3
WHERE keycol = @key;

— Or with a subquery:

UPDATE dbo.T1
SET (c1, c2, c3) = (SELECT T2.c1, T2.c2, T2.c3
FROM T2
WHERE T2.keycol = T1.keycol)
WHERE keycol = @key;

— Logically equivalent to:
UPDATE dbo.T1
SET c1 = (SELECT T2.c1
FROM T2
WHERE T2.keycol = T1.keycol),
c2 = (SELECT T2.c2
FROM T2
WHERE T2.keycol = T1.keycol),
c3 = (SELECT T2.c3
FROM T2
WHERE T2.keycol = T1.keycol)
WHERE keycol = @key;

---

- Comparison Predicates
-—————————————————————————————————-

— The operators: AND follow the rules for Equality operations in the standard.

— equals operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) = (@p1, @p2, @p3);

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE c1 = @p1
AND c2 = @p2
AND c3 = @p3;

- Consider NULL comparison as TRUE
- For details see: https://connect.microsoft.com/SQLServer/feedback/details/286422/add-language-and-optimizer-support-for-iso-distinct-predicate?wa=wsignin1.0
WHERE (c1, c2, c3) IS NOT DISTINCT FROM (@p1, @p2, @p3);

— With composite joins:

SELECT T1.keycol AS T1_key, T2.keycol AS T2_key
FROM dbo.T1 JOIN dbo.T2
ON (T1.c1, T1.c2, T1.c3) = (T2.c1, T2.c2, T2.c3);

— not equals operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) <> (@p1, @p2, @p3);

— Consider NULL vs. non-NULL comparison as TRUE
WHERE (c1, c2, c3) IS DISTINCT FROM (@p1, @p2, @p3);

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE c1 <> @p1
OR c2 <> @p2
OR c3 <> @p3;

— The operators: , , AND follow the rules for Ordering operations in the standard.

— less than operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) < (@p1, @p2, @p3);

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1 < @p1)
OR (c1 = @p1 AND c2 < @p2)
OR (c1 = @p1 AND c2 = @p2 AND c3 < @p3);

— greater than operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) > (@p1, @p2, @p3);

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1 > @p1)
OR (c1 = @p1 AND c2 > @p2)
OR (c1 = @p1 AND c2 = @p2 AND c3 > @p3);

— less than or equals operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) <= (@p1, @p2, @p3);

— Logically equivalent to:
SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1 = @p1 AND c2 = @p2 AND c3 <= @p3)
OR (c1 = @p1 AND c2 < @p2)
OR (c1 < @p1);

— greater than or equals operator:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) >= (@p1, @p2, @p3);

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1 = @p1 AND c2 = @p2 AND c3 >= @p3)
OR (c1 = @p1 AND c2 > @p2)
OR (c1 > @p1);

---

- IN AND BETWEEN Predicates
-—————————————————————————————————-

— IN:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) IN (SELECT c1, c2, c3
FROM T2);

— if the subquery returns the rows R1, R2, �, Rn, the above query is then equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) = R1
OR (c1, c2, c3) = R2
OR …
OR (c1, c2, c3) = Rn;

— BETWEEN:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) BETWEEN (pl1, @pl2, @pl3) AND (pr1, @pr2, @pr3) ;

— Logically equivalent to:

SELECT keycol, c1, c2, c3
FROM dbo.T1
WHERE (c1, c2, c3) >= (pl1, @pl2, @pl3) AND (c1, c2, c3) <= (pr1, @pr2, @pr3) ;

---

- MIN/MAX Aggregates
-—————————————————————————————————-

SELECT grpcol, MAX
FROM dbo.T1
GROUP BY grp;

— Logically equivalent to:

WITH C AS
(
SELECT grpcol, c1, c2, c3,
ROW_NUMBER() OVER AS rownum
FROM dbo.T1
)
SELECT grpcol, c1, c2, c3
FROM C
WHERE rownum = 1;

— with explicit ROW keyword
SELECT grpcol, MAX)
FROM dbo.T1
GROUP BY grpcol;

<=-=Aug 11 2010 8:23AM=-=>

I like Itzik’s ideas, all but the MIN/MAX construct.

To me MIN would behave similar to COALESCE in that it perhaps aggregates c1 & c2 & c3, then chooses the min result of the three.

I’m also not sure how column aliases would work when row constructs are used in the SELECT statement.

<=-=Aug 11 2010 9:15AM=-=>

There are platforms that support scalar MIN/MAX-like aggregates called LEAST/GREATEST. Actually, it would be nice to see those in SQL Server too. But I think that the potential confusion can be resolved with an explicit use of the ROW keyword: MAX). As for aliasing, normally the construct would return the original column name, but could be nice to see such a feature allows assigning our own aliases. Something like: MAX) AS (myc1, myc2, myc3).

<=-=Jan 1 2011 6:30PM=-=>

There is a bit of a clunky way currently in which aggregates can be used across columns.

SELECT [name]
,[number]
,(SELECT MAX FROM (SELECT low AS n UNION ALL SELECT high) d) n
FROM [master].[dbo].[spt_values]

<=-=Mar 12 2012 8:51AM=-=>

Having used these in ORACLE over EIGHT YEARS AGO it’s stunning that this has been on the very distant back-burner for OVER FIVE YEARS.

Would Microsoft care to update loyal community members on the status of this request, please?

<=-=Feb 20 2013 9:14PM=-=>

Can we have an update on this suggestion please?

Echo Phil Brammer, really like Itzik’s suggestions below. Although rather than messing with the well established MIN/MAX aggregate functions, I would suggest adding a new functions for evaluating the MIN or MAX over a value list (not set) e.g. MIN_VAL(val1, val2, val3), whereas MIN would work as per Itzik’s suggestion.

If this is considered for a future version of SQL Server, please implement it according to the ISO SQL standard. In other words, implement the SQL Standard , which provides regular expression support through the operator [NOT] SIMILAR TO, which in the standard remains separate from LIKE.

Like Steve, I would also like to stress that any implementation should be as per ANSI (SIMILAR predicate). The CLR functionality is not a relevant design consideration.

Dear Itzik.

Thanks a lot for your feedback… and the strong voting support for this feature. Indeed, as you know, I am very much in favor of extending our functionality in this area. For a variety of reasons we did not get this into SQL Server 2008, but we are certainly looking into it for a future release.

Keep the votes and comments coming…

I am a big fan of the ranking functions and partition by clause. I used them extensively. It was a fantastic inclusion in 2005. However, I can’t tell the number of times I wished DISTINCT worked with the count function. I can’t believe it wasn’t included in 2008!! So I’ve added my vote to get this in ASAP.

<=-=Sep 15 2009 7:08AM=-=>

yes this would be very helpful. I’m sitting here frustrated over my inability to do this.

<=-=Dec 14 2009 5:53PM=-=>

Count(DISTINCT Col1) OVER (PARTITION BY Col2) would solve my problem perfectly! I need to know if the number of items is different than the number of distinct items. Solving this another way will be tricky.

<=-=Dec 14 2009 6:05PM=-=>

If we could nest ranking functions this would do the same thing (of course, we can’t so this code doesn’t work):

SELECT
X,
Y,
Rnk = Max(Dense_Rank() OVER (PARTITION BY X ORDER BY Y)) OVER (PARTITION BY X)

SELECT ‘a’ x, 1 y

UNION ALL SELECT ‘a’, 2

UNION ALL SELECT ‘b’, 1
) Z

I use the over() clause quite a bit and it’s been very useful, however only now am I really wanting more functionality from it, so figured I’d bump this thread. I’m good with workarounds, and not entirely sure I, “need” additional functionality, however it would surely lend itself to more elegant solutions.

It would be nice to be able to use the result of an OVER clause in a where clause too. I’m always having to make wrappers just to filter the result of an OVER clause.

<=-=Oct 31 2012 10:23AM=-=>

Say you are reporting on a price comparison engine.

In a given time period, you want a count of how many users clicked through to each website whose prices you compare.

On the assumption that users make at most one purchase per website per day, you want to dedupe the cases where users click through many times.

The Referrals table contains one row per click-through.

To get this deduped count for yesterday, you should be able to write

SELECT
COUNT OVER (PARTITION BY Website) AS DedupedUserCount
FROM Referrals
WHERE
ReferralTime >= ‘2012-10-30’ AND
ReferralTime < ‘2012-10-31’

This fails with the disappointing message

Msg 10759, Level 15, State 1, Line 11 Use of DISTINCT is not allowed with the OVER clause.

Plamen Ratchev provides a workaround (see Workarounds) using the DENSE_RANK function in a subquery and the MAX function.

But we should be able to do it as declaratively as the SQL grammar allows!

<=-=Jan 10 2013 12:47PM=-=>

I really hope this feature is a part of SQL Server 2012 because I just tried to use it in 2008 and came here to find it’s not supported. I’m using something like the code below to get the result.

SELECT COUNT AS DedupedUserCount
FROM Referrals AS R
GROUP BY R.Website
HAVING ReferralTime >= ‘2012-10-30’ AND ReferralTime < ‘2012-10-31’;

I know this is a much newer comment on this but we are currently on 2008 R2 for SQL Server due to business constraints and having this functionality would make solving my current problem so incredibly easy.

You should fix this. It is not working in SQL Server 2014 also. This limitation was reported almost 9 years ago.

I’m currently migrating an established application from another database platform to SQL Server. There’s a big, powerful chunk of the app missing due to the absence of the WINDOW clause functionality.

Thank you for providing this feedback. We will consider adding this functionality in a future release of SQL Server. If there are other rich formatting requirement that you have, please do add details to this item for those additional features also.

<=-=Dec 3 2009 11:21AM=-=>

When is this justify text going to be out? You commented on 1/27/2009 and it’s nearly a year since this has been resolved. How come the Silverlight team and accommodate the top requests within a few month but SQL team cannot do the same?

<=-=Mar 23 2010 12:37PM=-=>

In many cases a reporting tool is the best option to provide formatted data to clients, shareholders, and other individuals where the appearance of the report is as important as the accuracy of the data. It has to look good, not just be correct.

This is a serious deficiency, and while SSRS “isn’t a word processor” exporting reports out to a word processor or page layout tool for re-formatting is unacceptable.

For this reason, I’m loathe to reccommend SSRS to my clients where any such formatting is needed. At least two of my clients in the last two years decided on other tools simply because of this missing feature in an otherwise great reporting system.

<=-=Sep 4 2010 11:23PM=-=>

desperate need of this feature for legal documents

<=-=Oct 18 2010 6:08AM=-=>

I Think that is very important that Reporting Services have this option. For example We returned to Crystal Reports with a number of hours lost by our programmers. It is unacceptable as other functions have priority over an issue that can be considered basic.

<=-=Dec 7 2010 6:11AM=-=>

We would like to design our reports with SSRS but as long as Full Justify text is not possible we’ll still use Crystal.

<=-=Dec 17 2010 2:02PM=-=>

I need Full Justify Text for my mutual fund client’s sales brochures published from SQLServer. I’m trying to keep them from going to Crystal, but they have a serious need for the Justify feature and may have to Crystalize. That would be such a shame.

<=-=Mar 6 2011 1:59AM=-=>

It has been there for more than two years now and no comment from Microsoft since been posted, so I really want to know what is the status of this suggestion and is it really so hard to take such long period?

<=-=May 9 2011 3:52PM=-=>

Thanks for all the additional feedback. To shed some light on why the feature is not as trivial as it may seem, we need to consider it across the various rendering extensions (HTML, GDI, PDF, and so on), among other considerations. The high vote count does help us prioritize this feature for a future release.

<=-=Jul 25 2011 10:50AM=-=>

Will this be included in Denali? It is critical and even if it is not trivial to implement, try telling a client that a basic feature such as this is too difficult to implement.

<=-=Aug 26 2011 1:50PM=-=>

I second Brian’s comment. Clients don’t necessarily care how complicated the feature is to implement…they just know that it’s possible in Microsoft Word, so it can’t be THAT hard. :-)

Any light at the end of the tunnel for this one? Denali perhaps?

<=-=Sep 4 2011 8:56AM=-=>

This is a major issue! It is hard to explain to our customers that it can’t be done in this reporting tool. Usually the reply is “then let’s use another reporting tool”.

Is there any solution now ?
Todays, we can make fire with an IPHONE but we can’t justify a text in a report.

<=-=Nov 24 2011 4:56AM=-=>

As far as I can see today, using Denali RC0, Reporting Services are basicly the same and NO, there’s no fully justify feature.
What’s more it does not work the “align=”justify" HTML option (in which I hoped).

<=-=Dec 1 2011 3:58PM=-=>

Even if it is not easy to implement, it is a BASIC function requested for years! I cannot understand why it is still no available. Many users (and me too) have to use another reporting tool because of this missing feature… Have the project manager some Crystal reports Equities? ;-)

Please provide this feature – we are about to lose a large contract to convert to SQL Server Reporting Services because this basic feature does not exist. Even trying to include HTML tags with the justify attribute does not work in SQL RS. I really, really hope that this feature has been added to DENALI or somebody has missed the boat.

<=-=Mar 21 2012 11:35AM=-=>

Just confirmed…this is NOT part of Denali (SQL Server 2012 Reporting Services) – so much for including the feature in a “later release”. Are we now going to wait for SQL Server 2016? Please put this is a service pack release for SQL Server 2012!

<=-=Mar 22 2012 3:14AM=-=>

I just tried a before reading Shardenazar’s comment and got disappointed. I forgot the html markup type deliberately cripples almost everything – security has priority. Still, fixing html markup would be an easy solution.

A control IMHO can’t be a solution – didn’t its output need to be a bitmap by design?

I’ve often thought the sources of some of the SSRS should be public – would offer an alternative in so many cases – extensibility documentation – unsortable excel exports – etc etc…

Sorry, can’t resist: [quote] Even Access can do this ! [/quote] Hey – no insults below the belt please!

In case anyone was wonder/hoping, this feature did not make it into SQL 2014. The only item on the “what’s new” page is Chrome support.

I completely agree.

I’ve googled and can’t even find a work around to create a professional style report with a table of contents.

Would be extremely useful.

<=-=May 26 2011 8:15AM=-=>

Agreed. This needs to be built into the product.

In addition to what was said above, I would request that this table of contents page end up as page 1 when you export to PDF and end up as page 1 when you print. (The document map doesn’t print, and it only appears in the bookmarks tab in Adobe Reader.)

A hack of a workaround is mentioned here. I�m not wild about it. We have to deploy a custom assembly� we have to store this info in a database table� we have to account for storing the page count per report per parameter combination per user (in case there�s data level user security). So it would be a day or two of effort� hardly in the plan.

I think this goes further than computed columns, as a filtered index can’t be used for something as simple as WHERE num % 2 = 0 (with no computed columns in sight). I really want to see filtered indexes become more useful.

<=-=Dec 7 2009 10:29AM=-=>

Greg,

Thanks for your feedback. I agree we should allow filtered indexes on persisted computed columns, and should support more complex filter expressions, at some point in the future. We restricted the functionality for the first version but we’ll consider this for a future release. The documentation should be more precise about the restrictions on predicate expressions. I’ll follow up on that.

Best regards,
Eric

<=-=Dec 8 2009 8:56PM=-=>

I was AMAZED when I could not create a filtered index on computed column.

But I as APPALLED and DUMBFOUNDED when I could not create a filtered indexes on persisted computed column?

So a future release should address computed columns. But a patch should address persisted computed columns for SQL 2008.

Otherwise, it’s yet another “half-baked” feature.

<=-=Jan 4 2010 1:02PM=-=>

Like SQL Ranger, I can’t believe this doesn’t work. Especially when you can’t compare two columns from the table in the predicate. These limitations take filtered indexes from interesting and very useful to pretty much a throwaway feature. Quite sad.

<=-=Jan 4 2010 1:15PM=-=>

This functionality should definitely be in SQL11, if not in 2008 R2. There are almost no new Engine or T-SQL enhancemnets in 2008 R2.

Even more annoying is the vague error message when you do something like this:

Worth noting that SSDT thinks that this is supported – a database project containing an index filtered on a deterministic persisted computed column will build with no errors, then fail to deploy.

<=-=Nov 9 2015 2:24AM=-=>

It is a shame. I am not able to use complex logic in the filter index definition (I mean an OR clause). So, I have created a computed column to fix this but the filter index creation is not working as well.

<=-=Nov 4 2007 11:40AM=-=>

TVPs should definitely not be limited to being read-only. Without updateability, they will be perceived as an “impaired” new feature. As lead author in the upcoming Programming Microsoft SQL Server 2008 book by MS Press, I urge the SQL team to support updateable table value parameters.

<=-=Nov 14 2007 4:25PM=-=>

I strongly agree that this is much needed to help solve/improve many business problems. Implementing this functionality will lead to building better applications.

<=-=Dec 10 2007 3:45PM=-=>

Hi Erland,
Thanks for the feedback on this. We have recieved similar feedback from a large number of customers. Allowing table valued parameters to be read/write involves quite a bit of work on the SQL Engine side as well as client protocols. Due to time/resource constraints as well as other priorirites, we will not be able to take up this work as part of SQL Server 2008 release. However, we have investigated this issue and have this firmly in our radar to address as part of the next release of SQL Server. We appreciate and welcome the feedback here.

Please note that it was an explicit limitation in my suggestion that read-write
table parameters would only be available when a stored procedure calls
another. The READONLY limitation would still apply to client communication,
at least for SQL 2008. Surely that would reduce the amount of work needed
considerably, wouldn’t it?

<=-=Dec 19 2007 11:27PM=-=>

Well i really dont see huge benefits of having only a READONLY limitation in SQL 2008, like Erland rightly says at least have a READWRITE on the server side. Client sides are not as much a priority as much as server side is.They are good to have but server sides are must have.

<=-=Jan 30 2008 9:33PM=-=>

<=-=Sep 25 2008 2:23PM=-=>

I just ran into this. It would definitely be helpful to call a stored proc from another stored proc and be able to pass a resultset from the inner stored proc to the calling stored proc.

<=-=Nov 11 2008 8:39AM=-=>

Contrarily to what other people said, I see strong benefits to read-only table-valued parameters. First and foremost being that they are convenient and fast as hell (if you tried doing the equivalent of an SqlBulkCopy with them, you know what I’m talking about).

On the other hand, I only see advantages to having them be read/write.

<=-=Dec 15 2008 10:49AM=-=>

If people want the choice of readonly or not, make this an option in the declaration, that way any efficiency benefits of readonly can be enjoyed when wanted, and the flexibilty to write to the table can be had the rest of the time

<=-=May 15 2009 4:09PM=-=>

Any possibility this can be implemented in sp2, before Kilimanjaro? (could be option to add readwrite, or require readwrite if want readwrite, so would not break or change any existing code). readwrite table parameter feature is extremely useful—remember how dependent server side programming is on what t-sql makes available, and the particular weaknesses of t-sql versus general purpose programming languages. readwrite tvps would be a huge benefit b/c compensating for a major weakness in t-sql.

<=-=Jan 19 2010 5:28AM=-=>

Totally agree. This would be very handy for consuming applications such as SSIS & SSRS. I have run into problems with sprocs on numerous occasions that do not adhere to an output contract and hence do not behave as expected. Please make sure that if you implement read/write OUTPUT parameters that the SSIS team is aware of them and can implement an OLE DB Source component that can use them.

<=-=Jan 30 2010 7:04AM=-=>

I agree with this. But there is a simpler change that would make life a lot simpler:
allow this
select into #temptable exec(@sql var)
Which means: capture the output if dynamic sql into a table, be a “normal” table or a temp table.

<=-=Jul 9 2010 3:53AM=-=>

i would like be able to chooose if the params will be read only (perhaps favoring performance) or not (favoring programability for sure)

<=-=Dec 3 2010 9:48AM=-=>

This is a fantastic suggestion. I especially like Erland’s argument that a status flag indicating success or failure for each record, which might be useful. And the fact that you might want to use the table as a work table without the overhead of copying the whole parameter table to a local table first, which is just a waste of resources.

On another note, anything that Erland Sommarskog recommends for SQL Server needs to be taken with great seriousness. If he has identified a weakness, we should believe him!

David Walker

<=-=Apr 8 2011 10:14AM=-=>

Extremely important feature for sql developers- please schedule for implementation as soon as possible.
Agree with fotis12- please allow specifying readonly | out.

<=-=Jun 15 2011 8:54AM=-=>

Yes, this is sorely needed due to the considerable limitations of UDFs. There are many times that I’ved wanted the tabular output of something that cannot be written as a UDF (most recently, restore headeronly), but in order to do so have to pollute the code with the declaration of a temp table or table variable… with 51 columns in this case, everywhere you want to be able to use it.

Not being able to encapsulate that SOMEHOW makes code both ugly and difficult to maintain.

At the very least, it would be nice to be able to create a table type and then reuse that type in code, taking the pain and maintainability problems out of insert-exec. For example:

create type MyTableType(i int, j int, k int)

declare @T table(MyTableType) = exec (string | procedure)

or, if relation assignment is never going to happen (another thing that really should be in the language…)

declare @T table(MyTableType)
insert @T exec (string | procedure)

<=-=Aug 23 2011 3:40PM=-=>

When the performance of parsing XML in SQL Server is well documented plus the added development effort in turning this into more primitive data types, I’m surprised that the work around proposed uses this approach.

<=-=Jan 23 2013 2:00PM=-=>

Your suggestion made my list.

I was thinking like this….

looser coupling for existing proc to proc calls:

Wouldn’t it be nice if there was a TSQL command that could return result sets from a called proc as an array where each member could be assigned to a table variable or each one could be accessed as one directly?

tighter coupling:

allow me to update a passed table variable and make it possible to return a table variable as an output

something in between:

allow for both approaches to work together somehow.

I also would like the ability to model a udt after an existing table and have it keep pace with that table as it is altered.

Anyway, you get my vote.

<=-=Jun 27 2013 3:03PM=-=>

This is a very useful idea and I would fully welcome modifiable table parameters. This would also work around the problem that Insert Into Exec cannot be nested (see “Cannot have nested INSERT … EXEC”). However Microsoft’s last feedback is in 2007 – can they update this suggestion with progress details?

<=-=Jul 29 2013 3:43AM=-=>

Please can this idea be included in SQL Server 2014 – it would be very useful.

This idea (ID 299296) has now been open for NINE years, that should be enough development time to allow implementation. Please can this idea be included in SQL Server 2016, and please can Microsoft update the status. All the comments here are from experienced SQL Server users who are strong supports of the product, and it would be great if Microsoft could respect this support by providing regular updates.

<=-=Feb 3 2017 1:48AM=-=>

This idea is approaching its 10th birthday and it’s time it was implemented! I have spent many hours scripting work arounds using varchar(max) or XML, and implementing this idea would greatly improve the usability of SQL Server. Erland Sommarskog’s suggestion on 10/12/2007 means no client protocol work is required, so the required work is in SQL Server core itself. Please can Microsoft follow the suggestions and pleas of the experienced SQL Server users who have posted below. Will Rayer MCSE

Having SQL Server behave in predictable ways is important. Improvements like this one sort of bring the db engine into a fuzzier area of behaviour. Maybe good in this case, but a slippery slope.

Consider this situation. A dba sees a query with terrible performance that is holding locks on resources everywhere. The dba fixes the query with a query hint and the index suddenly gets dropped. What’s worse? An error on the query? Or a poorly performing query (with a warning) that is once again locking resources everywhere.

<=-=May 20 2008 4:32PM=-=>

I agree with the sentiment of this DCR. Failing queries when an INDEX hint can’t be creates excessive dependence between the physical structure of the data and the application code. But we must find a way to provide a warning to users, e.g. through the SQL error log or a DMV or showplan, if the index hint is not honored. We’ll consider this for the next release.

Note that you get the kind of behavior I described if you use USE PLAN in a plan guide. That is a possible workaround for now.

Thanks! -Eric

<=-=May 20 2008 4:54PM=-=>

This is a major issue for ISVs that have third-parties customizing their software. Even if the core application doesn’t use index hints, some customized code may. Dropping indexes becomes unmanageable risk. Unfortunately we cannot use aliases to solve this problem (at least in 2005). That would be another solution if we could create the alias for existing index that will have the same name as the index that has been dropped. Or SQL Server can simply ignore the hint which is even better.

Any update on this? I happened to see this in the event Blocked Process Report:

That is, here the call stack is available. Through the sqlhandle it is possible to retrieve
the objectids of the calling procedures.

If if it’s available this way, it can’t be too difficult to expose this in a DMV. Only exposing the
sqlhandle would not match with my observation with permissions above, but since you probably
only want this code in a few places, this could be dealt with adding extra privs with
certificate signing.

I have to agree with Erland. A callstack would be awesome. Someway of logging it outto an eventlog or table. I have been trying to figure out how to create such a thing to show the where the error occured back up through to the originating call.

<=-=Oct 15 2009 6:32AM=-=>

I’d find it useful for debugging purpose. Also, debugging option in SQL 2008 meets my need to some degree.

<=-=Feb 23 2010 8:19PM=-=>

In addition to a standard T-SQL callstack of functions/stored procedures, it would also be useful if the “call stack” could also “magically” indicate which if any *.NET methods triggered the stored procedure.

Suppose I have a VB.NET function like
Public Function GetDataSource() As DataView
’ return result of T-SQL Stored Called sp_makeInventoryDataSource
End Function

Then suppose sp_makeInventoryDataSource called a T-SQL function called fn_getItemName(itemID).

Then the calls stack for fn_getItemName should not only contain sp_makeInventoryDataSource but it should also show the VB.NET function GetDataSource and might look like:
[T-SQL CAll] fn_getItemName
[T-SQL Call] sp_makeInventoryDataSource
[VB Call] GetDataSource

Guys, this feature is unavailable for us more then ten years. Please add it to SQL Server 2012.

June 4th, 2013: “Voting is no longer enabled on this topic” – so is Microsoft about to give us this feature in SQL 2014 (2012 R2)?

+1 in lieu of the inactive voting button.

Yes. Please. Pretty please. With a cherry on top?

We have an issue right now, where certain emails are going out from a sproc, but we cant find any reason why this sproc would be getting run.
It would be SOOOOO incredibly helpful, to be able to see the stack trace and see what the heck is calling the sproc.

Yes, still a valid issue, needed it today, we have tons of existing code where we do it the hard way, passing in names from callers.

Twelve years now, and nothing but crickets?

How many votes does something need before MSFT will seriously consider implementing it?
