SYMPTOMS

When you run a query that contains many MIN aggregates or MAX aggregates in Microsoft SQL Server 2000, the query plan may take longer than expected to compile. You may also receive one or more error messages that are similar to the following:

Error message 1

Server: Msg 701, Level 19, State 1, Line 1 There is insufficient system memory to run this query.

Error message 2

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.

Error message 3

Server: Msg 8651, Level 17, State 1, Line 1 Could not perform the requested operation because the minimum query memory is not available. Decrease the configured value for the 'min memory per query' server configuration option.

Typically, this problem occurs when you run a query that contains more than 100 aggregates.

CAUSE

This problem occurs when the query optimizer search algorithm consumes more computer resources than expected to compile a valid query plan. When the query optimizer generates various query plan alternatives, one alternative that may be generated is an index seek that contains a TOP 1 clause. The results are ordered forward for the MIN aggregate and ordered backward for the MAX aggregate. This ordering of the results may cause the query optimizer search algorithm to take longer than expected to compile the query plan when there are many aggregates.
