Hello,
is it possible to access trigger variables in dinamic sql statement:
CREATE TRIGGER EMPLOYEE_UPDATE FOR EMPLOYEE AFTER UPDATE EXECUTE
(
VAR
EVENTTABLEID FIXED(10);
COLNAME VARCHAR(30);
STMT VARCHAR(100);
COLCHNG FIXED(38);
I FIXED (38);
SET COLCHNG = 0;
SET I = 1;
DECLARE COLNAME_CURSOR CURSOR FOR
SELECT COLUMNNAME FROM DOMAIN.COLUMNS WHERE TABLENAME = 'EMPLOYEE';
WHILE ($RC <> 100) DO
BEGIN
FETCH COLNAME_CURSOR INTO :COLNAME;
SET stmt = 'IF (OLD.' || colName || ' <> NEW.' || colName || ') THEN
SET colChng = ' || colChng|| ' + ' || i;
EXECUTE stmt;
SET I = I*2;
END;
CALL ADMIN.GENERATE_EVENTS(1, :OLD.ID, 2, :COLCHNG);
)
EXECUTE stmt; doesn't work
it should do next task:
IF (NEW.COLNAME <> OLD.COLNAME) THEN
SET colChng = colChng + i;
for every column of table "EMPLOYEE" but returns an error.
Can I obtain such result in trigger code ?
Thank you for your support, Dusan.
