Example: INSERT Using a PERIOD Value Constructor
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;
