Update Statistics

NORECOMPUTE

Disable the automatic statistics update option, AUTO_UPDATE_STATISTICS, for the specified statistics. If this option is specified, the query optimizer completes this statistics update and disables future updates.

To re-enable the AUTO_UPDATE_STATISTICS option behavior, run UPDATE STATISTICS again without the NORECOMPUTE option or run sp_autostats.

For more information about the AUTO_STATISTICS_UPDATE option, see ALTER DATABASE SET Options (Transact-SQL).
