创建触发器时mysql出错

Question

我有两个表格详细信息并购买。

当我尝试在购买桌子上创建触发器时，这似乎是一个错误

"#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 '' at line 3 "

听到我的代码

create TRIGGER afterinsert after insert on purchase for each row
BEGIN 
set @qnty=(select quantity from stock_detail where brand_name = new.brand);
if(@qnty>=1) then
update stock_detail set quantity=@qnty+new.quanty;
end if;
END;

Answer 1

试试这个：

delimiter //
create TRIGGER afterinsert after insert on purchase for each row
BEGIN 
set @qnty=(select quantity from stock_detail where brand_name = new.brand);
if(@qnty>=1) then
update stock_detail set quantity=@qnty+new.quanty;
end if;
END;//
delimiter ;
