如何在SQL Server中使用Update语句加入

Question

以下代码适用于MS Access，但我无法使其与SQL Server 2008一起使用。

UPDATE Borrow INNER JOIN BorrowDetails 
ON Borrow.BorrowID = BorrowDetails.BorrowID 
SET BorrowDetails.Returned = True 
WHERE BookID = 1 AND MemberID = 1

请知道。

Answer 1

UPDATE BorrowDetails
SET BorrowDetails.Returned = True 
FROM BorrowDetails
INNER JOIN Borrow ON Borrow.BorrowID = BorrowDetails.BorrowID 
WHERE BookID = 1 AND MemberID = 1

Answer 2

请改为尝试：

UPDATE bd
SET bd.Returned = 1
FROM BorrowDetails bd
INNER JOIN Borrow b ON bd.BorrowID = b.BorrowID    
WHERE b.BookID = 1 AND b.MemberID = 1

Answer 3

UPDATE x
SET x.Returned = True 
FROM (
      SELECT Returned 
      FROM Borrow INNER JOIN BorrowDetails ON Borrow.BorrowID = BorrowDetails.BorrowID 
      WHERE BookID = 1 AND MemberID = 1
      ) x
