COLLECT STATISTICS (QCD Form) always collects its own fresh statistics on candidate index columns, even if a statistical profile of the specified columns or index columns already exists in the data dictionary or QCD for table_name, to ensure that index analyses are always performed using current statistics.

Fresh statistics are also collected whenever you perform an INSERT EXPLAIN request and specify the WITH STATISTICS clause. See INSERT EXPLAIN for more information.
