MERGE語句中的Incorret語法

Question

我試圖從臨時表執行MERGE到我們的常規表中。但是，SQL Server Management Studio在UPDATE語句中ZipCodeTerritory表名稱上顯示錯誤。

我以前沒有寫過MERGE，但是我看不出下面的語法有什麼問題。由於智能感知錯誤報告可能非常不具描述性，所以任何人都可以看到下面的查詢有什麼問題？

MERGE INTO ZipCodeTerritory as Target 
USING ZipCodeTerritoryTemp as Source 
ON 
Target.Id = Source.Id 

WHEN MATCHED THEN 

UPDATE ZipCodeTerritory SET Target.ChannelCode = Source.ChannelCode, Target.DrmTerrDesc = Source.DrmTerrDesc, Target.IndDistrnId = Source.IndDistrnId, 
    Target.StateCode = Source.StateCode, Target.ZipCode = Source.ZipCode, Target.EndDate = Source.EndDate, Target.EffectiveDate = Source.EffectiveDate, 
    Target.LastUpdateId = Source.LastUpdateId, Target.LastUpdateDate = Source.LastUpdateDate, Target.ErrorCodes = Source.ErrorCodes, 
    Target.Status = Source.Status 
WHERE Target.Id = Source.Id 

WHEN NOT MATCHED THEN 

INSERT INTO ZipCodeTerritory (ChannelCode, DrmTerrDesc, IndDistrnId, StateCode, ZipCode, EndDate, EffectiveDate, LastUpdateId, LastUpdateDate, ErrorCodes, Status) 
VALUES(Source.ChannelCode, Source.DrmTerrDesc, Source.IndDistrnId, Source.StateCode, Source.ZipCode, Source.EndDate, Source.EffectiveDate, Source.LastUpdateId, Source.LastUpdateDate, Source.ErrorCodes, Source.Status) 

Answer 1

Check syntax，Update和Insert條款是沒有表名。它也不是Merge Into簡單Merge。

MERGE ZipCodeTerritory as Target 
    ... 
WHEN MATCHED THEN  
    UPDATE SET Target.ChannelCode = Source.ChannelCode ... 
WHEN NOT MATCHED THEN 
    INSERT (Ch ... 

爲什麼？表名是多餘的，因爲它在Merge子句中被通知。
