PRUNE_NO - Unable to prune. PRUNE_DEFAULTS - Partitioning field is only set to DEFAULT values, only need to check pruning for one row where the DEFAULTS values are set. PRUNE_YES - Pruning is possible, calculate the used partition set by evaluate the partition_id on row by row basis.
True if pruning has been completed and can not be pruned any further, even if there are subqueries or stored programs in the condition.
Some times it is needed to run prune_partitions() a second time to prune read partitions after tables are locked, when subquery and stored functions might have been evaluated.
