  • To run this macro with CollectSummaryStats ('Y'), the SystemFE user needs the SELECT and STATS privileges on InputDatabaseName.

    SELECT lets the user check whether the statistics are stale and STATS lets the user collect statistics on objects.

  • CollectSummaryStats ('Y') increases the accuracy of the CDS values that the macro returns for the database. However, if the statistics are stale or not already collected for InputDatabaseName, the macro must collect new statistics, which increases macro running time.
