SQL 2016 SP3 CHECKDB WITH EXTENDED_LOGICAL_CHECKS problem.

  • This seems to be the same problem which occurred with SQL2017 CU21 and is now fixed:

    https://www.sqlservercentral.com/forums/topic/sql2017-cu21-checkdb-with-extended_logical_checks

    This problem is consistent with msdb. When I run:

    DBCC CHECKDB ([msdb]) WITH NO_INFOMSGS, ALL_ERRORMSGS, DATA_PURITY, EXTENDED_LOGICAL_CHECKS;
    PRINT @@ERROR;

    error 2706 is always returned even though no errors are reported.

    If EXTENDED_LOGICAL_CHECKS is removed CHECKDB runs fine.

    Like the SQL2017 CU21 problem I suspect there is nothing actually wrong with msdb. ie This would not stop me from applying SP3 to production.

     

  • I got the same on SQL 2019 with latest CU12.

    DBCC CHECKDB ([msdb]) WITH NO_INFOMSGS, ALL_ERRORMSGS, DATA_PURITY;

    PRINT @@ERROR;

    -- result: 0

    DBCC CHECKDB ([msdb]) WITH NO_INFOMSGS, ALL_ERRORMSGS, DATA_PURITY, EXTENDED_LOGICAL_CHECKS;

    PRINT @@ERROR;

    -- result: 2706

  • You are right. I missed it because our two SQL2019 servers were created after I had spotted the problem in SQL2017 so used the test restore routine which ignored error 2706.

    I have also noticed that the error is there again in SQL2017 CU26.
