Question

我有查询创建触发器：

CREATE TRIGGER `Insert` AFTER INSERT ON `HistoryBalance`
 FOR EACH ROW INSERT INTO Winners (name) VALUES  (new.ProductID)

但现在我想得到条件：

if (new.Status = 'user'){
   CREATE TRIGGER `Insert` AFTER INSERT ON `Balance`
 FOR EACH ROW INSERT INTO Winners (name) VALUES  (new.ProductID)
}

请告诉我克利特在我的情况下如何正确触发？

Answer 1

你可以这样做：

delimiter $$
CREATE TRIGGER balance_insert AFTER INSERT ON Balance
    FOR EACH ROW
BEGIN
    if (new.Status = 'user') then
        INSERT INTO Winners(name) VALUES  (new.ProductID);
    end if;
END; $$
delimiter ;
