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. SQL 2017: "SET FMTONLY ON" doesn't return any resultset on UDF w/ COMPATIBILITY_LEVEL=140

    Our application uses at various places the SchemaOnly attribute (see https://msdn.microsoft.com/en-us/library/system.data.commandbehavior(v=vs.110).aspx). Lately, we noticed some strange errors when the application runs against a DB on SQL Server 2017. I boiled the issue down to the attached repro script in T-SQL, that shows clearly that SQL Server doesn' return any metadata, if a table-valued function is called using SET FMTONLY ON with COMPATIBILITYLEVEL=140. But it works as expected using COMPATIBILITYLEVEL=130. As I didn't find any word on this breaking change in the docs, I consider this a bug.

    Thanks for the suggestion. We’ll take a look at it and prioritize accordingly.

  3. Ability to run specific SQL Agent job steps

    Occasionally a user may need to run only specific steps of an agent job, or need the job stop after a certain step.

    While SQL Server Agent currently provides the ability to "Start job at step", this is all the flexibility the user has at runtime. Anything beyond that requires the job to be edited.

    It would be useful for those with permission only to run (not edit) jobs to have greater flexibility at runtime. E.g. a screen which allows the user to choose which steps to run or skip for that particular execution.

  4. T-SQL Common Table Expression "Materialize" Option

    T-SQL Common Table Expression "Materialize" Option

    I have run into a couple performance and results issues using Common Table Expressions (CTEs).

    The first case is where I coded a data retrieval as a single, large query with a CTE that is referenced multiple times in the query. The CTE has an expensive query. I was able to determine, via execution plans, etc., that the results of the CTE were being recalculated multiple times, resulting in slow execution. I rewrote the data retrieval as multiple steps where the query of the CTE was first executed into a table variable, and I…

  6. Bug in SSMS on Statistics Properties screen

    There is a "Update statistics for these columns" checkbox In SQL Management Studio in Statistic Properties dialog.

    However when I click on this checkbox and press OK it has no effect what so ever. Statistics are not updated and when I try to script the action I get "There is no action to be scripted".

  7. SET STATISTICS IO should also show schema name for tables

    When you use schemas in your database, and you have the same table names in multiple schemas, it is not clear, which schema the table belongs too in the output of the SET STATISTICS IO. E.g. a table called Profile, or configuration in different schema is very common at our databases

    Today the output is just
    Table 'Profile'. Scan count 1, logical reads 123, physical reads 1, read-ahead reads 121, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
    Table 'Profile'. Scan count 3, logical reads 13, physical reads 1, read-ahead reads 342, lob logical reads 0,…

  8. In-Memory OLTP - allow removal of Filegroup for memory_optimized_data

    It should be possible to remove the memoryoptimizeddata Filegroup and files, if all in-memory tables and procedures have been deleted.

    Currently you cannot do this "by design", however this is a potential blocker to people using this technology due to the "no-going-back once it's enabled". It is now several years since Hekaton was first released - support for this feature is long overdue!

    At present you get errors such as:
    Cannot drop the last memory-optimized container
    The filegroup ... cannot be removed because it is not empty.

    Thanks for the suggestion.
    We’ll consider it for a future release.

    Are there specific limitations imposed when you have the filegroup, e.g., no database snapshot, that hold you back from creating the filegroup?
    Or is it only the feeling of not being able to turn back?

  9. Maintenance Plan Portability

    Maintenance Plans should be scriptable, deployable and maintainable without the need to manually create/update a plan on each server/instance. Current functionality requires the DBA to manually generate a SQL Maintenance Plan one at a time for each instance in the environment. Built in SQL Maintenance Plans should be scriptable, deployable and maintainable with TSQL or in some automated fashion that will allow deployment to large enterprise environments that do not require the use of a GUI.

  10. In SQL Server Always oafter a failover, SQL Server keep the connections open without killing any session

    Hi Msft Team!
    I want to suggest one improvement to your sql server always on feature. Normally, once we perform failovers we need to ask app teams for maintenance windows... or in worst cases ,if this happens automatically, we need to discover the RCA of this because all the application or users connections had been terminated. Also many times that we had automatic failovers or perform failovers with long executions happening the secondary instance turned into recovery state because it was waiting for this session to finish to synchronize again. So, is it possible to add the capability for failovers…

  13. Move measures between tables in SSAS Tabular

    In Power BI Desktop and Power Pivot, you can easily move a DAX measure between tables (since a measure isn't actually related to a table anyway).
    However, this is not possible in SSAS Tabular (current version: 2017). You can cut a measure, but only paste it again in the same table, not in a different table.
    The current process is to create a duplicate of the original measure with a different name, delete original measure and then rename the new measure. Time consuming.

  14. UTF-8 in SQL 2019: An error occurred while executing batch. Error message is: Internal connection fatal error. Error state: 15, Token : 0

    In SQL Server 2019 CTP 2, the query below gets a fatal error when executing in a database that has a "_UTF8" default Collation. The fatal error is:

    "An error occurred while executing batch. Error message is: Internal connection fatal error. Error state: 15, Token : 0"

    and the connection is terminated.

    Better yet, if you go to the "Results" tab and scroll down to the bottom, it should completely crash SSMS (I tested in 17.9 ; have not yet tried 18.0). Of course, this is when using "TOP (142)" or greater. If using a value of 128 - 141…

  16. Incorrect error message for missing parameter with sp_execute_external_script

    I use spexecuteexternal_script and I spell a parameter name incorrectly. For instance:

    EXEC spexecuteexternal_script @language = N'Python',

     @script = N&#39;import re, pandas
    

    Ret = InputDataSet
    Ret["an"] = pandas.Series([re.sub("[^0-9]", "", i) for i in Ret["an"]], index = Ret.index, dtype = "int32")
    ',

     @input_data_1 = N&#39;SELECT an FROM alphanum&#39;, 
    
    @output_data = N&#39;Ret&#39;

    The error message is

    Msg 214, Level 16, State 175, Procedure spexecuteexternal_script, Line 1 [Batch Start Line 4]
    Procedure expects parameter '@params' of type 'ntext/nchar/nvarchar'.

    Which is confusing , since spexecuteexternal_script has a parameter by that name, but it is not mandatory.

  17. Sql Server Management Studio / Always Encrypted Parametrization

    The order of the parameters in SSMS (v.17.9.1) seems to be critical when using encrypted and not encrypted columns in one statement.

    Declaring the not encrypted variable before encrypted vars works, the other way it doesn't work (ERROR: ncryption scheme mismatch for columns/variables .. see more details and example in the file attached.)

    best regards,
    Roman

  18. SSMS 18.0 RC1 is prompting for authentication upon scripting out an object from Object Explorer.

    I know this is happening on version 15.0.18098.0.

    The Scenario: You have a server in Object Explorer that you authenticated to. You navigate to a table in one of the databases. You right-click on the table. You choose "Script Table as" -> "CREATE To" -> "New Query Editor Window". You are then prompted with the "Connect to Database Engine" window for server selection and authentication.

    This is not something that happens in SSMS 17. I installed this yesterday and when I did so I choose the option to port over all my settings from 17. Everything else has been working…

  19. T-SQL for changing table column order

    Once a table is created, the ordinal position of the columns is fixed. This is especially problematic for large data warehouse tables, where new columns are expected to be added over time.

    The only solution currently to re-order columns is to drop and recreate the table (or let the SSMS designer do this for you), but this is often not feasible for a large, highly used table, and it cannot be easily scripted.

    Please add some ALTER syntax that will allow changing column order.

  20. Indicate "morally equivalent" forced plan where use_plan = true but is_forced = 0

    Currently, if you force a plan in query store (or if it is forced by automatic plan correction), the exact plan which is forced has isforced = 1 in sys.querystoreplan. In the plan properties, there is no useplan indication.

    After this plan is forced, often a "morally equivalent" plan will be compiled, which has a different queryplanid and different costs, but the same plan shape.

    This "morally equivalent plan" has isforced = 0 in sys.querystoreplan. In the execution plan properties, useplan = true.

    These "morally equivalent plans" are currently difficult…
