Assume that you have a table that has the sql_variant data type in Microsoft SQL Server 2012 or in Microsoft SQL Server 2014. When the statistics are updated manually or automatically, you receive the following error message:
Location: <File Path>\_retypesbase.inl:526
Expression: PbValGetConst()[CSsVariant::OFF_VER] == CSsVariant::CURR_VER
Process ID: xxxxxx
Msg 3624, Level 20, State 1, Line 1
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
NoteDBCC CHECKDB ('<database name>') WITH NO_INFOMSGS does not report any database inconsistencies.
