The following example uses IS [NOT] UNTIL_CHANGED in the PPI partitioning expression to check whether or not the ending bound of a Period expression is UNTIL_CHANGED.

   CREATE TABLE TESTUC
     (A  INTEGER,
      B  PERIOD (DATE),
      C INTEGER)
     PRIMARY INDEX (A)
     PARTITION BY
        CASE_N (END (b) IS UNTIL_CHANGED,
                END (b) IS NOT UNTIL_CHANGED, UNKNOWN);
