MySQL的插入查詢，如果條件插入觸發

我使用WampServer與MySQL版本匹配後：5.7.9和phpMyAdmmin版本：4.5.2MySQL的插入查詢，如果條件插入觸發

我想在表1 INSERT觸發器後寫一個插入表2中的數據如果數據不存在於表2中。下面是我的查詢：

DROP TRIGGER IF EXISTS `insert_customer`; 
CREATE TRIGGER `insert_customer` AFTER INSERT ON `installations` 
FOR EACH ROW BEGIN 
    IF (SELECT COUNT(*) FROM `customers` WHERE `customers`.`phone` = NEW.`phone`) = 0 
    THEN INSERT INTO `customers` (`phone`, `imei`, `platform`, `version_code`) VALUES (NEW.`phone`, NEW.`imei`, NEW.`platform`, NEW.`version_code`); 
    END IF; 
END;

這給了我下面的錯誤：

#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 '' at line 4

我和分隔符太嘗試：

DROP TRIGGER IF EXISTS `insert_customer`; 
DELIMITER | 
CREATE TRIGGER `insert_customer` AFTER INSERT ON `installations` 
FOR EACH ROW BEGIN 
    IF (SELECT COUNT(*) FROM `customers` WHERE `customers`.`phone` = NEW.`phone`) = 0 
    THEN INSERT INTO `customers` (`phone`, `imei`, `platform`, `version_code`) VALUES (NEW.`phone`, NEW.`imei`, NEW.`platform`, NEW.`version_code`) 
    END IF; 
END; 
| 
DELIMITER ;

這給了我下面的錯誤：

#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 'END IF; 
END' at line 5

我在做什麼g在這裏？任何幫助？

仍然會收到同樣的錯誤。 :( – Muntasir

最後，我知道了。正確的SQL是：

DROP TRIGGER IF EXISTS `insert_customer`; 
DELIMITER | 
CREATE TRIGGER `insert_customer` AFTER INSERT ON `installations` 
FOR EACH ROW BEGIN 
    IF (SELECT COUNT(*) FROM `customers` WHERE `customers`.`phone` = NEW.`phone`) = 0 THEN 
     INSERT INTO `customers` (`phone`, `imei`, `platform`, `version_code`) VALUES (NEW.`phone`, NEW.`imei`, NEW.`platform`, NEW.`version_code`); 
    END IF; 
END;| 
DELIMITER ;

The;在我的INSERT查詢結束時解決了我的問題。：D
