Subsequent entry of the following request on the same table refreshes the statistics for the empno -name index, along with any other statistics previously collected for the employee table, including PARTITION statistics.

     
COLLECT STATISTICS ON employee;

The following request collects statistics on o_orderstatus for the first time without specifying a THRESHOLD option. The database collects the statistics and the system uses the SYSTEM THRESHOLD, which is the default threshold option when DBSControl fields DefaultUserChangeThreshold, SysChangeThresholdOption, and DefaultTimeThreshold are not set.

     COLLECT STATISTICS
     COLUMN o_orderstatus
     ON orders;
