Assume that you run a query against a nonclustered columnstore index in Microsoft SQL Server 2016. If the total amount of data in fixed length columns is close to the row size limit, for example, select * from an index that contains an int, a bigint, a datetime, a char (8000), and a char (29); and a key column is involved in a predicate, you receive the following error message:
Msg 8624, Level 16, State 27
Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services
