When you run an UPDATE statement on a table that has a clustered columnstore index (CCI) in Microsoft SQL Server 2016, you may receive an assertion error that resembles the following:
Location: "bpbatch.cpp":240
Expression: (BP_VECTOR_ID)(iNew + 1) == iNew + 1
SPID: 55
Process ID: 1556
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 Hotfix from Technical Support.
Msg 596, Level 21, State 1, Line 0Cannot continue the execution because the session is in the kill state.
Msg 0, Level 20, State 0, Line 0A severe error occurred on the current command. The results, if any, should be discarded.
