sp_updatestats executes UPDATE STATISTICS, by specifying the ALL keyword, on all user-defined and internal tables in the database. sp_updatestats displays messages that indicate its progress. When the update is completed, it reports that statistics have been updated for all tables.

sp_updatestats updates statistics on disabled nonclustered indexes and does not update statistics on disabled clustered indexes.

sp_updatestats updates only the statistics that require updating based on the rowmodctr information in the sys.sysindexes catalog view, thus avoiding unnecessary updates of statistics on unchanged rows.

For databases with a compatibility level below 90, executing sp_updatestats does not preserve the latest NORECOMPUTE setting for specific statistics. For databases with a compatibility level of 90 or higher, sp_updatestats does preserves the latest NORECOMPUTE option for specific statistics. For more information about disabling and re-enabling statistics updates, see Using Statistics to Improve Query Performance.

Requires membership in the sysadmin fixed server role, or ownership of the database (dbo).
