Summary

The configuration setting for the query governor cost limit option is lower than the cost that the SQL Server optimizer estimated for the specified query. By default, the query governor cost limit option is set to 0, which allows all queries to run. However, on this instance of SQL Server an upper limit was specified by setting the option to a number greater than 0. Query plans with an anticipated cost larger than this value are not started.

For more information, see “query governor cost limit Option”, “How to set the query governor cost limit option (Enterprise Manager)”, and “Query Tuning Recommendations” in Books Online.

Resolutions

Any of the following actions will prevent the message from occurring for this query:

Tune the query to reduce the estimated execution time below the limit value.
Verify that statistics are up to date on tables and indexes referenced by the query. You may need to execute UPDATE STATISTICS or DBCC DBREINDEX.
Set the query governor cost limit option back to the default of 0. This will allow all queries to run.
Raise query governor cost limit option to a value higher than the estimated number of seconds for this query to execute.
