SYMPTOMS

When you try to compile and run certain queries, the SQL Server optimizer may occasionally return the following error message:
Server: Msg 8623, Level 16, State 1, Line 1
Internal Query Processor Error: The query processor could not produce a query plan. Contact your primary support provider for more information.
Note This problem is not limited to any particular query construct, database environment, or statistics distribution. The error message is based on certain costing inconsistencies that occur when the SQL Server optimizer calculates the cost that is associated with various possible query plans for the query.
