写触发器遇到的问题:列前缀与表名或别名不匹配

CREATE TRIGGER trig1 ON WorkTask
FOR UPDATE
AS
if WorkTask.Amount>WorkTask.Finish OR WorkTask.Overfulfill=1
begin
raiserror('不能超额完成',16,1)
rollback transaction
end

以上代码在检查语法时就报错:列前缀WorkTask与查询中所用的表名或别名不匹配,请问……

CREATE TRIGGER trig1 ON WorkTask
FOR UPDATe
AS
if exists(select 1 from inserted where Amount>Finish and Overfulfill=1)
begin
raiserror('不能超额完成',16,1)
rollback transaction
end

--改为这样

表名应该是inserted吧 if (select proleftchance from t_project where inserted.proid=t_project.proid)>0 and (select applystate from t_project where inserted.proid=t_project.proid)='已通过'
