The following request collects statistics on the multicolumn set (o_orderstatus, o_orderkey) for the first time and specifies the FOR CURRENT option. The database collects the requested statistics, but because of the FOR CURRENT specification, it does not store the THRESHOLD setting nor does it store the default threshold options from the DBSControl fields DefaultUserChangeThreshold and SysChangeThresholdOption.

     COLLECT STATISTICS
     USING SYSTEM THRESHOLD FOR CURRENT
     COLUMN (o_orderstatus, o_orderkey)
     ON orders;
