Question

我正在尝试从临时表中将MERGE导入我们的常规表。但是，SQL Server Management Studio在ZipCodeTerritory语句中的UPDATE表名称上显示错误。

我之前没有写过MERGE，但我无法看到下面的语法有什么问题。由于智能感知错误报告可能与Management Studio非常具有描述性，因此其他任何人都可以看到下面的查询有什么问题吗？

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)

Check syntax，Update和Insert子句没有表名。它也不是Merge Into简单Merge。

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

为什么呢？表名是多余的，因为它在Merge子句中被告知。

MERGE语句的语法不正确
