SQL Server

Microsoft SQL Server 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 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. Microsoft Command Line Utilities 15 for SQL Server fails to recognize pre-requisite ODBC 17

    SQLCMD docs state that Command Line Utilities 15 requires ODBC 17 (https://docs.microsoft.com/en-us/sql/tools/sqlcmd-utility?view=sql-server-2017). However, the actual Command Line Utilities 15 installer does not recognize a previously installed ODBC 17.

    Installing ODBC 13 will allow the Command Line Utilities 15 installer to complete successfully, but we end up with errors later presumably due to the Command Line Utilities 15 actually requiring OBDC 17 functionality. Installing both versions 13 and 17 seems to get around this, but obviously requires installation of both packages.

    Our server for testing this is a 64 bit Windows 2008 R2 Enterprise with SP1.

  2. SSIS package fails to start - application lock timeout in SSISDB.catalog.create_execution

    Details are described here:
    https://connect.microsoft.com/SQLServer/feedback/details/783291/ssis-package-fails-to-start-application-lock-timeout-in-ssisdb-catalog-create-execution

    In short: when a scheduled job tries to execute an SSIS package , there's a time-out in the communication between the job and the SSISDB database. The package is never executed. The original bug reports was closed as duplicate (no duplicate to be found though).

    I encountered this bug in SQL Server 2017, patched to the latest CU.

    Error message: Failed to execute IS server package because of error 0x80131904. Description: The operation failed because the execution timed out. Source: .Net SqlClient Data

  3. Update produces impossible result

    The following produces an illogical result:

    DECLARE @Target table
    (

    c1 integer PRIMARY KEY, 
    
    c2 integer NOT NULL,
    c3 integer NOT NULL

    );

    DECLARE @Source table
    (

    c1 integer NULL, 
    
    c2 integer NULL,
    c3 integer NULL,

    INDEX c CLUSTERED (c1)

    );

    INSERT @Target

    (c1, c2, c3) 
    

    VALUES

    (1, 0, 0);
    

    INSERT @Source

    (c1, c2, c3) 
    

    VALUES

    (1, 2, NULL),
    
    (1, NULL, 3),
    (1, 4, 4);

  4. SSMS screen is not correctly redrawn when switching tabs

    Sometimes when switching between tabs in SSMS the screen is not correctly refreshed (redrawn).
    The result is a corrupt screen partly showing the previous tab contents and partly showing the newly active tab contents.
    In particular this happens when using "Database Diagrams" tabs.

    This has been a permanent bug through a number of the latest SSMS releases including this release:
    Release 16.5.1
    File version: 13.0.16100.1

    This has been reported more times than you have used SSMS. MS are too incompetent and lazy to fix it.

    Here is the link to another which also has a link to another report

    I can replicate this on multiple different computers, each with freshly installed Windows (either 8.1 or 10) and latest of all drivers. It happens both with Intel integrated graphics (for me is HD 4600) and NVidia cards. It’s clearly a bug in how you’re using the Visual Studio shell.

    This is absolutely HORRIBLE!! When closing a tab, then attempting to execute the query in a tab that was already open and is now focused (because you just closed one), you see the wrong text in the tab, and…

  5. Add setting so LEN counts trailing whitespace

    Maybe there is a historic reason why LEN('a') and LEN('a ') return the same number.

    But that's stupid.

    The internet is awash with people like me who were stunned to discover this counter intuitive quirk (Google it).

    None of the solutions to this problem are particularly elegant or efficient:
    https://stackoverflow.com/questions/2025585/len-function-not-including-trailing-spaces-in-sql-server/2025587

    I'm assuming since this has been baked in for ages, we can't change default behavior.

    So how about:
    - Add a parameter to the LEN function to count white space
    - Add an SQL Option that more generally keeps SQL Server's hands off my white space - everywhere

  7. Identical symmetric keys do not work between SQL Server 2017 and other SQL Server version

    hi everybody!

    I believe, there is a general product issue in SQL Server 2017. The problem concerns encrypting & decrypting data using the same symmetric key on different servers.
    I have an issue in SQL Server 2017 CU3 (version 14.0.3015.40). I need to create identical symmetric keys on two servers of different versions, as it is described in MS article:

    https://docs.microsoft.com/en-us/sql/relational-databases/security/encryption/create-identical-symmetric-keys-on-two-servers

    These steps work well within and between different versions of SQL Servers (2012, 2014, 2016), but not between SQL Server 2017 and any other server.
    I can create identical symmetric keys on SQL Server 2012, 2014 and 2016. So…

  8. SSIS 2016 packages abort with �Unexpected Termination� message

    We have a straight forward implementation in deploying the SSIS 2016 packages (migrated from SSIS 2008 R2) onto the SSISDB and then calling these packages through a SQL Agent job.
    The job calls the parent wrapper package and this in turn will call the necessary child packages based of the files that has to be loaded.

    However, when we execute the same package multiple times, the execution of the child package fails with the status �Unexpected Termination�.
    We do not find any error messages within the Execution reports of the SSIS package. This issue will be resolved once we redeploy…

  9. SEQUENCE gets reset on Publish from SSDT DB Project

    When you add a sequence to a database project and have it start at 1 and then deploy the project to a database, the first time it gets created correctly.
    When you get more values and the sequence next value is 100 and then publish the project again, the publish generates an ALTER SEQUENCE dbo.SequencObject RESTART WITH 1; statement and that should not happen when the sequence object already exists.

  15. Traceflag 460 causing truncation errors on code paths that are not followed

    This is an odd one. I have tested this on both SQL Server 2017 CU12 and CU13 (in a container and on my production boxes).

    If you have an IF/ELSE condition, and you are inserting into a table variable in the ELSE, and that INSERT would cause a truncation issue, it will throw an error, EVEN IF THE CODE IS NOT EXECUTED.

    I have attached a reprop script that creates a database called "Repro" and runs the code. When TF460 is enabled, the ELSE block with throw an error when inserting into a table variable, even though it is impossible…

  16. Key Lookup against Columnstore Index Causes Slow Query Execution

    On tables with a clustered columnstore index and a b-tree index on the same table, some parameter sets get an execution plan with an index seek against the b-tree, and then key lookup (in row mode) against the columnstore. This is extremely expensive, and most of the queries against larger columnstores never complete. The remedy is to hint the columnstore index in the query. I can supply plans as needed, but apparently can't upload here.

  17. 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.

  18. Index rebuild removes persisted sample percent

    The UPDATE STATISTICS statement has a (relatively) new PERSISTSAMPLEPERCENT option, but when rebuilding an index which previously had statistics updated with this value set the persisted sample percent is reset back to default. I would expect the rebuild to create statistics with 100% sampling (which it does), but leave the persisted sample percent intact so that automatic statistics updates would use the previously specified value.

  19. SSMS - Right-click menu option to "Design" tables configured as Temporal Tables is missing

    I am using the new Temporal Table feature on certain tables in my database.

    When I navigate to such tables via SSMS Object Explorer, I have found that the "Design" right-click menu option is not present for Temporal Tables. (Or as SSMS labels them, "System-Versioned" tables.)

    The "Design" option is, however, still available for NON-temporal tables.

    Thank you for taking time to post this issue!
    I can confirm that Design option in SSMS Object Explorer is not available for temporal (system-versioned) tables.
    Unfortunately, we do not plan to include a fix for this issue in the upcoming release.
    We might include it as an improvement in a future release, though.
    How important for you is to have this option available for temporal tables?

  20. Columnstore REORGANIZE command increases modification_counter on table statistics

    Reorganizing a columnstore index can, in some cases, cause the modificationcounter on the table's statistics to increase. This is unexpected because while the underlying structure of the table is being changed, the data itself isn't being modified. This can lead to issues where SQL is automatically updating statistics the next time a query is executed against the table in cases where the modificationcounter increases a significant amount because of the REORGANIZE. This has been particularly problematic for our large fact table with 150+ billion rows and full scan statistics across 40+ columns.

    Attached is a reproduction script with…
