简单的插入触发器，怎么修改，在线等
看了如下代码应该明白我什么意思。。该怎么改呢

CREATE trigger TransportRecordsInsertTrg
on TransportRecords_FID_1
for insert
AS
declare @MaxTemperature float 
declare @MinTemperature float

select @MaxTemperature=m.MaxTemp,@MinTemperature=m.MinTemp from
MonitorRules m inner join inserted i
on m.BarCode=i.BarCode
if i.Temperature >@MaxTemperature or i.Temperature <@MinTemperature
begin
insert into MonitorLog (BarCode,RID,TemMonitor) Values(m.BarCode,m.RID,i.Temperature)
end

RETURN

[解决办法]

--以下：
CREATE trigger TransportRecordsInsertTrg
    on TransportRecords_FID_1
    for insert
AS
begin
    if EXISTS
    (
select *
FROM MonitorRules m 
inner join inserted i on m.BarCode=i.BarCode
WHERE i.Temperature >m.MaxTemp or i.Temperature <m.MinTemp
    )
    begin
    insert into MonitorLog (BarCode,RID,TemMonitor) 
select m.BarCode,m.RID,i.Temperature
FROM MonitorRules m 
inner join inserted i on m.BarCode=i.BarCode
WHERE i.Temperature >m.MaxTemp or i.Temperature <m.MinTemp
    end
END

目前的不能运行啊，只是我理想的结果

试试这样呢：

CREATE trigger TransportRecordsInsertTrg
on TransportRecords_FID_1
for insert
AS
declare @MaxTemperature float 
declare @MinTemperature float

select @MaxTemperature=m.MaxTemp,@MinTemperature=m.MinTemp from
MonitorRules m inner join inserted i
on m.BarCode=i.BarCode


insert into MonitorLog (BarCode,RID,TemMonitor) 
select m.BarCode,m.RID,i.Temperature
from MonitorRules m 
inner join inserted i
        on m.BarCode=i.BarCode
where i.Temperature >@MaxTemperature or i.Temperature <@MinTemperature
go
