使用MySQL存储功能

Question

我试图使用mysql存储功能。 功能：在触发

DELIMITER $$ 
CREATE FUNCTION ChangeHistory(newValue VARCHAR(255), oldValue VARCHAR(255), attributeName VARCHAR(255), action VARCHAR(255), entityId BIGINT(20), modifiedBy BIGINT(20)) RETURNS TINYINT(1) 
    NOT DETERMINISTIC 
BEGIN 
    IF newValue != oldValue THEN 
    INSERT INTO ChangeHistoryPlayer 
    SET 
     action = action, 
     timeCreated = now(), 
     entityId = entityId, 
     modifiedBy= modifiedBy, 

     attributeName = attributeName, 
     oldValue = oldValue2, 
     newValue = newValue2; 
    END IF; 
RETURN 1; 
END 

函数调用：

USE `XXX_admin`; 
DELIMITER $$ 
CREATE TRIGGER `player_AUPD` AFTER UPDATE ON `player` FOR EACH ROW 
BEGIN 
    ChangeHistory(NEW.firstName, OLD.firstName, 'firstName', 'AFTER_UPDATE', NEW.entityId, NEW.modifiedBy); 
END 

错误（changeHistoy之后和之前 “（”）：

syntax error, unexpected '(' expecting ':' 

为什么

Answer 1

CREATE TRIGGER `player_aupd` after UPDATE 
ON `player` 
FOR EACH row 
begin 
    SELECT Changehistory(new.firstname, old.firstname, 'firstName', 'AFTER_UPDATE' 
     , 
         new.entityid, new.modifiedby); 
end 

添加选择s应该做的伎俩！

希望这会有所帮助！
