if with mysql results in syntax error - mysql

Question

I need to use a if statment in my mysql trigger. It looks like that:
set #countentry = (SELECT count(id) as `id` FROM `tsc_page_have_wildcard` where idwildcard=1 and idpage=5);
IF #countentry <> 0 THEN
INSERT INTO `tsc_page_have_wildcard` (`idpage`, `idwildcard`) VALUES (#pageid, NEW.id);
END IF
By executing the trigger i get:
Error Code: 1064. You have an error
in your SQL syntax; check the manual that corresponds to your MySQL
server version for the right syntax to use near 'IF #countentry <> 0
THEN
INSERT INTO `tsc_page_have_wildcard` (`i' at line 1
The table struct is the following:
CREATE TABLE IF NOT EXISTS `tsc_page_have_wildcard` (
`id` int(11) NOT NULL auto_increment,
`idpage` int(11) NOT NULL,
`idwildcard` int(11) NOT NULL,
PRIMARY KEY (`id`),
KEY `idpage` (`idpage`,`idwildcard`),
KEY `idwildcard` (`idwildcard`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=8 ;
ALTER TABLE `tsc_page_have_wildcard`
ADD CONSTRAINT `tsc_page_have_wildcard_ibfk_1` FOREIGN KEY (`idpage`) REFERENCES `tsc_page` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
ADD CONSTRAINT `tsc_page_have_wildcard_ibfk_2` FOREIGN KEY (`idwildcard`) REFERENCES `tsc_wildcard` (`id`) ON DELETE CASCADE ON UPDATE CASCADE;
INSERT INTO `tsc_page_have_wildcard` (`id`, `idpage`, `idwildcard`) VALUES
(1, 1, 1),
(2, 1, 2),
(3, 1, 3),
(4, 1, 4),
(5, 1, 5),
(6, 41, 4),
(7, 41, 5);
Does anyone know why this if statment isnt working in my trigger?

Answer 1

This code should work:
DELIMITER $$
CREATE /*!50017 DEFINER = 'root'#'localhost' */ TRIGGER `win` AFTER INSERT
ON `tsc_page_have_wildcard` FOR EACH ROW
BEGIN
SET #countentry =
(SELECT
COUNT(id) AS `id`
FROM
`tsc_page_have_wildcard`
WHERE idwildcard = 1
AND idpage = 5) ;
IF #countentry <> 0
THEN
INSERT INTO `tsc_page_have_wildcard` (`idpage`, `idwildcard`)
VALUES
(#pageid, NEW.id) ;
END IF ;
END $$
DELIMITER ;
Semi-colon(;) after END IF :-)
