mysql 存储过程和触发器 都报错了
#
#添加触发器(当删除留言时，删除留言的回复)
#
  create tigger tri_Tb_Message_delete  
  after delete
  on tb_message 
  FOR Each row
  BEGIN 
  delete from Tb_Reply where Message_Id in (select Message_Id from deleted);
  End;

#--添加存储过程（表名：Tb_Reply）
#insert

CREATE PROCEDURE pro_Tb_Reply_insert(
Message_Id int , --留言编号
Reply_Contents text, --回复内容
Reply_Time datetime='' --回复时间
)
BEGIN
Insert into Tb_Reply values(Message_Id,Reply_Contents,case is null (Reply_Time,'') when '' then getDate() when Reply_Time then Reply_Time end);
END;


给我帮我看看，貌似语法没有错，

------解决方案--------------------
DELIMITER $$
CREATE PROCEDURE pro_Tb_Reply_insert(
Message_Id int , --留言编号
Reply_Contents text, --回复内容
Reply_Time datetime='' --回复时间
)
BEGIN
Insert into Tb_Reply values(Message_Id,Reply_Contents,case is null (Reply_Time,'') when '' then getDate() when Reply_Time then Reply_Time end);
END$$
DELIMITER ;
------解决方案--------------------
当存储过程中有多个语句时，使用 delimiter // 来修改提交符。

delimiter //
create tigger tri_Tb_Message_delete 
after delete
on tb_message
FOR Each row
BEGIN
delete from Tb_Reply where Message_Id in (select Message_Id from deleted);
End;
//
