Re: Adding columns conditionally using SQL

CREATE PROCEDURE ROB.NEWFIELD
LANGUAGE SQL
BEGIN

DECLARE SQLSTMT CHAR (200) DEFAULT
'ALTER TABLE ROB.AAAKEY ADD DUH CHAR (10)';

IF NOT EXISTS (
SELECT * FROM QSYS2.SYSCOLUMNS SC WHERE SC.TABLE_NAME =
'AAAKEY' AND
SC.COLUMN_NAME = 'DUH')
THEN
EXECUTE IMMEDIATE SQLSTMT;
END IF;

END
