Determines whether or not to collect specific timing statistics.
ON, OFF
OFF
DBA permissions are not required to set this option. Can be set temporary, for an individual connection, or for the PUBLIC group. Takes effect immediately.
This option controls the collection of timing statistics on subqueries and some other repetitive functions in the query engine. This parameter should normally be OFF (the default) because for very short correlated subqueries, timing every subquery execution can slow down a query.
