---- 方法一：SQL2008之后版本支持
MERGE
dbo.tabminuteData AS Target1
USING 
Inserted Ins ON Ins.StationID = Target1.StationID AND Ins.ObservTime = Target1.ObservTime
WHEN MATCHED THEN 
UPDATE SET Target1.TT = Ins.TT,Target1.R1H = Ins.R1H
WHEN NOT MATCHED THEN
INSERT(
tt,R1H,StationID,ObservTime) 
VALUES( 
tt,R1H,StationID,ObservTime);




----方法二：SQL2008以前的版本用这个方法
--UPDATE 
-- tabminuteData 
--SET 
-- TT=b.TT,R1H=b.R1H
--FROM 
-- tabminuteData a JOIN inserted b 
--ON a.StationID=b.StationID AND a.ObservTime=b.ObservTime

--INSERT 
-- tabMinuteData 
--SELECT 
-- * 
--FROM 
-- inserted a
--WHERE NOT EXISTS( 
-- SELECT 
-- TOP 1 1
-- FROM 
-- tabminuteData b 
-- WHERE 
-- a.StationID=b.StationID AND a.ObservTime=b.ObservTime 
--)

-- 最后删除临时表的数据
DELETE Tmp_tabminuteData
