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

The following examples use 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 INSERT requests both use a PERIOD value constructor:

     INSERT INTO t1
     VALUES (1, PERIOD(DATE '2005-02-03', DATE '2006-02-04'));
     INSERT INTO t1
       SELECT a, PERIOD(b, c)
       FROM t2;
