Member Data Documentation

Used for QS_DYNAMIC_RANGE, i.e., "Range checked for each record". Used by optimizer tracing to decide whether or not dynamic range analysis of this select has been traced already. If optimizer trace option DYNAMIC_RANGE is enabled, range analysis will be traced with different ranges for every record to the left of this table in the join. If disabled, range analysis will only be traced for the first range.
