我需要使用触发器自动更新我的列。
这是代码:
create trigger sum update on `cash`
for each row
begin
UPDATE `cash`
SET `sum_cash` = `cash` + `sum_cash`;
end;
$$
我收到以下错误:
#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 'update on `cash` for each row begin UPDATE cash` SE' at line 1
我在 MySQL 上工作。
