Example: UPDATE Using a PERIOD Value Constructor - Advanced SQL Engine - Teradata Database

The following example uses tables t1 and t2, which are defined as follows:

     CREATE TABLE t1 (
       c1 INTEGER
       c2 PERIOD(DATE))
     UNIQUE PRIMARY INDEX (c1);

     CREATE TABLE t2 (
       a INTEGER
       b DATE
       c DATE)
     UNIQUE PRIMARY INDEX (a);

The following two UPDATE requests both use a PERIOD value constructor:

     UPDATE t1
     SET c2 = PERIOD(DATE '2007-02-03', DATE '2008-02-04'));
     UPDATE t1 FROM t2
     SET c2 = PERIOD(b,c)
     WHERE t2.a = 2;
