Question

我有当前的触发器：

CREATE TRIGGER ChangeAutoIncrementMeasures ON Measures 
 FOR EACH ROW BEFORE INSERT
 BEGIN 
  SET @@auto_increment_increment = 100
 END;

但我得到1064错误。我的错误在哪里？

编辑：应该是：

CREATE TRIGGER ChangeAutoIncrementVendors BEFORE INSERT ON Vendors 
FOR EACH ROW 
    SET @@auto_increment_increment = 10

Answer 1

SET语句后需要分号，BEFORE INSERT移动....

delimiter //

CREATE TRIGGER ChangeAutoIncrementMeasures BEFORE INSERT ON Measures 
FOR EACH ROW 
BEGIN 
  SET @@auto_increment_increment = 100;
END;
//

delimiter;

Answer 2

更改语法如下

CREATE TRIGGER ChangeAutoIncrementMeasures

BEFORE INSERT ON Measures 

FOR EACH ROW
 BEGIN
  SET @@auto_increment = 100;
 END

MySQL更新前触发器
