Is gather table stats already included in gather schema stats?

edited Oct 1, 2015 12:00PM in SQL Performance (MOSC) 4 commentsAnswered

Hi,

We want to make sure that the action plan being executed on our DB (11gR2) is the 'best' in order to minimize performance issues. For this, do I only need to run gather_schema_stats (or gather_database_stats) and it will include executing gather_table_stats?

Or do I need to run independent gather_table_stats on each tables on top of gather_schema_stats?

Thank you.

Howdy, Stranger!
