Question

CREATE TRIGGER pointclosedtrigger AFTER UPDATE ON points 
FOR EACH ROW BEGIN 
IF NEW.is_open='3' 
THEN 
    INSERT into point_history (idpoints,idmembers,action_time,action_type) 
    VALUES (OLD.idpoints,NEW.idmembers,NOW(),'2'); 
END IF; 
END 

Answer 1

你忘了定义分隔符

delimiter | 
CREATE TRIGGER `pointclosedtrigger` AFTER UPDATE ON `points` 
FOR EACH ROW BEGIN 
IF NEW.is_open='3' 
THEN 
    INSERT into point_history (`idpoints`,`idmembers`,`action_time`,`action_type`) 
    VALUES (OLD.`idpoints`,NEW.`idmembers`,NOW(),'2'); 
END IF; 
END 
| 
delimiter ; 

如果不定义另一个分隔符比;那么你的声明将在第一;结束，它将不完整。
