SQL-Server 2005:无法绑定多部分标识符....

Question

我的错误信息:

多部分标识符table2.ValidSince"无法绑定.

UPDATE table1
SET table1.ValidSince = table2.ValidSince
WHERE table1.ID = '5C954C6F-FFD7-454A-9E2B-000076523819'

如何更改更新以使其正常工作？

Answer 1

你需要加入 table2

UPDATE t1
SET t1.ValidSince = t2.ValidSince
From Table1 t1
Join Table2 t2 on t1.PKCol = t2.PKCol
WHERE t1.ID = '5C954C6F-FFD7-454A-9E2B-000076523819'
