SQL Server 2005，语法错误

Question

该行不起作用：（问题在最后一行）

SELECT Book_Name  
FROM Books  
WHERE (Year, Faculty) = (SELECT Year, Faculty FROM Books WHERE Book_Id = 1112);

我该如何解决？

Answer 1

    SELECT b.Book_Name  
      FROM Books b
INNER JOIN (Select Year, Faculty From Books Where Book_Id = 1112) b2
        ON b.Year = b2.Year and b.Faculty = b2.Faculty

如果没有内部联接，替代方法是

SELECT b.Book_Name
  FROM Books b
 WHERE Year In (Select Year From Books Where Book_ID = 1112)
   AND Faculty In (Select Faculty From Books Where Book_ID = 1112)

但是，如果是家庭作业，则应该自己动手：-p

Answer 2

联接最好，但是如果不能（由于作业限制），请尝试以下操作：

SELECT
    Book_Name  
    FROM Books  
    WHERE
        Year IN (SELECT Year FROM Books WHERE Book_Id = 1112)
        AND Faculty IN (SELECT Faculty FROM Books WHERE Book_Id = 1112)
