我尝试了什么：
我研究了如何更新2和sql命令文本更多的表格，这是他们给我的解决方案：
What I have tried:
I researched on how to do a sql command text for updating 2 and more tables and this is what they gave me as a solution:
UpdateCommand=" UPDATE
individual i
INNER JOIN
address a
ON i.IndividualID = a.IndividualID
SET
i.FarmName = @FarmName,
i.FirstName = @FirstName,
i.MiddleName = @MiddleName,
a.Address1 = @Address1,
a.City = @City
WHERE
i.IndividualID=@IndividualID" >
i尽力复制他是怎么做到的，但似乎对我不起作用......
i tried my best to copy how he did it but it doesn't seem to work for me...
推荐答案
我刚发现它...
I just spotted it...
Update DVO d INNER JOIN
您不能在更新中使用别名...或者至少不能使用这样的...
Alias只能在FROM或JOIN中设置SQL ...
所以在更新中你必须这样做：
You can not use alias in update... or at least no like this...
Alias can be set in SQL only at FROM or JOIN...
So in UPDATE you have to do it like this:
Update DVO SET ... FROM DVO d INNER JOIN
