SQL Server

Microsoft SQL Server 2017 powers your entire data estate by supporting structured and unstructured data sources. It builds on previous versions of SQL Server, which have been industry leading for four years in a row and a leader in TPC-E. It scales to petabytes of data and allows customers to process big data through PolyBase using T-SQL over any data. SQL Server has also been the least vulnerable database during the last seven years. SQL Server 2017 brings data insights with business intelligence capabilities that provide analytics at a fraction of the cost on any device along with advanced analytics with support for R and Python.

More details about SQL Server are available in the SQL Server documentation.
If you have a technical issue, please open a post on the developer forums through Stack Overflow or MSDN.

  1. binary or string data would be truncated => error message enhancments

    if you have that error (in production), it's not obvious to see which column or row this error comes from, and how to locate it exactly.
    it's even more complicated if it's coming from a trigger, for example, and not the original insert/update.

    I have seen that oracle meanwhile gives clear information which column the error is raising, which actual data length was passed, and the column's max size.

    • Run DBCC CHECKDB WITH PHYSICAL_ONLY automatically in the background

      When RAID controllers are idle, they automatically check the storage to make sure it's still okay. Why not SQL Server too?

      Some of the pieces are there – for example, SQL Server already has the ability to watch for idle CPU times and run Agent jobs when it’s bored. For starters, that’d probably be good enough to save a lot of small businesses from heartache. For the databases over, say, 100GB, it’d be really awesome to have resumable physical_only corruption checking – tracking which pages have been checked (just like how the differential bitmap tracks page changes), with page activity…

      • Unable to deploy SSIS packages from Visual Studio 2017 (15.8.0)

        The latest version of Visual Studio 2017 (15.8.0) appears to have introduced a bug preventing deployment of SSIS project files.

        • Add a Keyboard Shortcut that Executes the Statement where the Cursor is placed

          Having to select statements by clicking and holding the mouse is just bad ergonomics. Request to have a keyboard shortcut which runs the current sql statement. The current sql statement is defined based on where the cursor is placed. For example, proposed shortcut runs only runs a single sql statement to the next semicolon. This shortcut would be an equivalent to Oracle's SQL developer's ctrl + enter shortcut. Note that this is probably the most used shortcut in SQL Developer and not having an equivalent on SQL Server Management Studio is disappointing. I know that not everyone ends their statements…

          • Add FOR CSV to facilitate CSV export

            We have FOR XML and FOR JSON. But it is not uncommon that people want to produce CSV files. This can be done with BCP, but it is not straightforward not the least if you want to add headers. And if you only want fields to be quoted when needed, BCP is not really what you are looking for. SSIS is also an alternative, but SSIS does not always fit in.
            Thus, it would be handy if there was a an option like FOR CSV, with a syntax like:
            FOR CSV [, HEADERS] [,DELIMITER(',')] [, QUOTE('"')]

            HEADERS would mean that…

              • Provide a mechanism for columns to automatically update themselves

                It is extremely common for databases to contain columns like "UpdatedDate," "UpdatedBy," etc. These columns work based on a trust model: As a database designer, I must trust that all of my downstream consumers will follow the intended rules, remembering to update the columns every single time any transaction occurs. And of course I have to trust that they'll put in the correct values. The only alternative to trust is to put ugly and potentially slow triggers in place to make sure everything happened the right way.

                This situation needs to change, and this is especially prevalent now, thanks to…

                  This is similar to my feedback located here: https://connect.microsoft.com/SQLServer/feedback/details/2769130/sql-2016-temporal-tables-with-triggers. The solution I suggest is similar to this, and could be used in many different cases developing using SQL server.

                  I would love this too. The issue is that many/most applications don’t use Windows Auth in the connection to SQL Server (connection pooling issues, etc), so SQL can’t get the User information

                  Just to clarify, I am not asking for an “automatically store user name” feature. I’m asking for “automatically store whatever I want, based on whatever expression I provide.” So the fact that the user name may or may not be available is not really relevant.

                  That said, there are plenty of workarounds for various situations. I imagine that if you’re using a shared connection, you can get some notion of “user” some other…

                • Database Level Option For Storing Wait Stats

                  SQL Server 2016 introduced Query Store, and SQL Server 2017 CU3 brought us aggregated wait stats at the query level. This is great information for data driven DBAs who need to be able to track plan changes over time, etc.

                  With that in mind, an additional data collector for wait stats per database would be a great product feature, independent from Query Store data collection.

                  We all know the limitations of the wait stats DMVs now:

                  - They're cumulative over time
                  - They're instance-wide
                  - There's a lot of potential noise from wait types that aren't registered

                    • Enable Query Store for collection on a read-only replica in an Availability Group

                      Currently, Query Store can only be enabled for the read-write database in Availability Group. As many customers issue queries against the read-only replicas, capturing query and performance metrics for those queries would be beneficial for understanding the workload, troubleshooting performance issues, etc.

                      • Easier identification of Implicit Transactions

                        Lots of ORMs let developers choose to enable implicit transactions, but there's no easy way to identity them without:

                        1. Running Profiler
                        2. Using the existing_connection XE session

                        Though it's a SET option, it's not included in the plan XML where SET options are identified, nor is it in sys.dm_exec_plan_attributes or sys.query_context_settings.

                        Using implicit transactions haphazardly can lead to some pretty nasty blocking chains. It should be much easier to identify when they're in use.

                        Thanks!

                        • MAX/MIN as NON-aggregate function

                          Please add the GREATEST/LEAST functions, just like in PostgreSQL/Oracle (with the same name for syntax-compatibility).
                          SQL-Server lacks functions for MAX/MIN as NON-aggregate function.
                          e.g. When I need the MAXIMUM of two values, or the minimum of two values (in columns, not rows).
                          When the value is a lengthy expression, it sucks having to write it in a case expression.
                          Also, the case-expression doesn't work for N > 2, and having to put it into a subselect-value-statement to use the aggregate functions as workaround affects readability severely (and thus maintainability).
                          Also, since SQL-server user-defined functions are damn slow, and on top…

                            The workarounds using CROSS APPLY or CASE expressions are difficult to manage and read. I’d love to see these implemented.

                            Can we please pass over the SSDT components to the Visual Studio team so this can be included as part of the Visual Studio 2017 installation process?

                            The VS team can then build out the installer in a way that SSDT is always compatible with their latest build and installer. We've been stuck with the break fix break fix loop with SSDT and incompatibility with VS upgrades for too long now. The SSDT team doesn't respond quickly enough, the latest example being SSDT 15.6/VS 2017 15.7.x installation issue, why are we waiting so long for an installer update?

                              For data warehouse staging tables or session state tables, when I don't want to change my application, I want to just specify CREATE TABLE AS UNLOGGED similar to how PostgreSQL does it. This way, my transaction logs aren't bloated, the data doesn't get copied around, and my inserts/updates/deletes are faster.

                                In 2014, memory optimized tables, and delayed durability can be used help mitigate these Issues. However neither of this are always completely viable solutions. Brent’s proposed solution is likely the simplest way to achieve this with the least amount of unwanted impact. It is important to note that other platforms implement similar functionality as well. Notably Oracle.

                                There are so many good things about this suggestion. I am amazed that SQL does not have the capability to turn off logging for certain tables that you define as no…

                              • Provide XEvents target directly into SQL Server table

                                Provide a way to directly write XEvent output directly into a SQL Server database table in a same or different instance and same or different database.

                                The goal being to be able to not have any events missed but have the entire stream captured to the table and also provide header information for when the capture table was created for easier management and deletion. Ideally there should be a purge task that could be activated to clean out such captures after X days.

                                XEvents is a great and powerful tool.
                                Customers should have an easier way to get it directly…

                                • Correctly escape predefined entities in deadlock XML

                                  If you create a table that has &, ", <, or > in the name, it's not correctly escaped in all instances of deadlock XML.

                                  This causes an error when trying to convert extended event/system health data to valid XML for analysis.

                                  • Use column aliases directly in SELECT clause

                                    It would be nice if queries like this were possible:

                                    SELECT
                                    A AS B
                                    ,C AS D
                                    ,D-B AS E
                                    FROM table

                                    In other words, use column directly in the SELECT clause where they are defined. Other database vendors have implemented this, so I assume it's not rocket science.

                                    Right now, we have to use subqueries just to define an extra calculation.

                                    • Explain why indexes were skipped

                                      Feature request: expose information about what indexes the optimizer considered while compiling an execution plan. Specifically, the index names and WHY the index was rejected for that particular query. This could potentially be included in per-operator execution plan properties (see attached mockup), an extended event target, or some other avenue.

                                      Reason: many developers and DBAs wonder why certain indexes on their tables aren't being chosen for specific queries. This gives them better tools to figure that out and make better use of the SQL Server product.

                                      I've blogged about this feature request in more detail here: http://joshthecoder.com/2018/06/21/feature-request-index-rejection-reasons.html

                                      • Add a built-in table of numbers

                                        There are several SQL problems that can be solved with a table of numbers or dates.
                                        This is a simple one-column table with numbers from 1 and up. Typical common problems
                                        solved by with such a function:

                                        o Show me sales for all months, including months for which there were no sales.
                                        o Iterate over all characters in a string in a set-based statements.
                                        o Any other query which you need to drive with a consecutive seres.

                                        It's easy to construct and fill such a table. However, there are a couple of problems
                                        with it:
                                        1) If you query needs…

                                          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…

                                          I have a very strange issue happening that is causing Script Task code to clear out. I have been able to test on 2-3 different machines. We are running SSDT 15.4 preview. The steps to reproduce were as follows.

                                          1. Create a script task inside of a foreach loop container. 2. Create a comment in the script task. 3. Change or add a variable mapping in the foreach. 4. Save package. 5. Open the script task and the comment will have vanished.

                                          As my last attempt for success,I have upgraded to 15.5.1 and the problem still exists.
