php myadmin sql 1064觸發器錯誤

Question

我試圖將以下sql命令上傳到php myadmin。但是，我有一些有趣的錯誤。我試圖解決它，但即使我仔細考慮，我也找不到錯誤發生的原因。

錯誤：

MySQL said: Documentation 
#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 'ON car_model 
FOR INSERT 
AS 
    declare @car_name VARCHAR(255)' at line 2 

SQL：

CREATE TRIGGER TRG_Update 
ON car_model 
FOR INSERT 
AS 
     DECLARE @car_name VARCHAR(255); 
     DECLARE @manufacturer_year VARCHAR(255); 
     DECLARE @car_type VARCHAR(255); 

     SELECT @car_name = i.car_name FROM inserted i; 
     SELECT @manufacturer_year = i.manufacturer_year FROM inserted i; 
     SELECT @car_type = i.car_type FROM inserted i; 

     INSERT INTO features 
       (car_name, manufacturer_year, car_type) 
     VALUES (@car_name, @manufacturer_year, @car_type); 
GO 

Answer 1

您正在使用SQL Server Trigger語法。下面是MySQL：

DELIMITER $$ 
CREATE TRIGGER TRG_Update 
AFTER INSERT ON car_model 
FOR EACH ROW 
BEGIN 
     INSERT INTO features (car_name, manufacturer_year, car_type) 
     VALUES (NEW.car_name, NEW.manufacturer_year, NEW.car_type); 
END $$ 
DELIMITER ; 

• MySQL CREATE TRIGGER Syntax

Answer 2

觸發應該是這樣的

TRIGGER TRG_Update BEFORE/AFTER INSERT/UPDATE/DELETE
