Question

我有以下查询将返回以下三个结果：

参加活动的所有学生的姓名参加活动的所有教员的姓名参加活动的所有公司联系人的姓名

SELECT        S.Last_Name + ', ' + S.First_Name AS Student_Name, '' AS Faculty_Name, '' AS Firm_Contact_Name, E.Event_name, E.Date
FROM            dbo.Student AS S INNER JOIN
                         dbo.Student_Enrollment AS SE ON S.Student_ID = SE.Student_ID INNER JOIN
                         dbo.Student_Attend AS SA ON SE.Enrollment_ID = SA.Enrollment_ID INNER JOIN
                         dbo.Event AS E ON SA.Event_ID = E.Event_ID
UNION
SELECT        '' AS Student_Name, F.Last_name + ', ' + F.First_name AS Faculty_Name, '' AS Firm_Contact_Name, E.Event_name, E.Date
FROM            Faculty F INNER JOIN
                         Faculty_Attend FA ON F.Fac_ID = FA.Fac_ID INNER JOIN
                         Event E ON FA.Event_ID = E.Event_ID
UNION
SELECT        '' AS Student_Name, '' AS Faculty_name, C.Last_Name + ', ' + C.First_Name AS Firm_Contact_Name, E.Event_name, E.Date
FROM            Firm_Contact C INNER JOIN
                         Firm O ON C.Comp_ID = O.Comp_ID INNER JOIN
                         Firm_Attend OA ON O.Comp_ID = OA.Comp_ID INNER JOIN
                         Event E ON OA.Event_ID = E.Event_ID

我想首先按照Student_name，Faculty_name，然后按Firm_Contact_Name按顺序排序。但是，当我在查询底部输入以下内容时

ORDER BY Student_Name, Faculty_Name, Firm_Contact_Name

我收到此错误

＆＃34; ORDER BY子句在视图，内联函数，派生表，子查询和公用表表达式中无效，除非还指定了TOP或FOR XML。＆＃34;

有什么想法吗？

这应该有效：

SELECT *
FROM (<your current query here>) AS X
ORDER BY Student_Name, Faculty_Name, Firm_Contact_Name

使用多个联合查询排序
