Question

我试图创建一个Table Function Total_Salary_By_Dept，它返回一个包含5列的表Total_Salary_By_Dept_Table：

Dept_No (Int)
Dept_Name (Char(30))
COUNT_Emp (INT)
SUM_Salary (INT)
AVE_Salary (INT)

所有公司数据库;

这是我到目前为止所做的，不确定我是否正确：

Use Company
GO


CREATE FUNCTION Total_Salary_By_Dept ()
RETURNS @Total_Salary_By_Dept_Table TABLE
  (
   Dept_No int,
Dept_name char(30),
   COUNT_Emp int,
   Sum_Salary int,
   AVE_Salary int
  )
AS
BEGIN
INSERT INTO @Total_Salary_By_Dept_Table
      Select e.Dept_No, d.Dept_Name, Count(e.Dept_No), SUM(e.salary) as Sum_Salary,AVG(e.salary) as AVE_Salary
from EMPLOYEE e
join DEPARTMENT d ON e.dno = d.dnumber
Group by e.Dept_No, d.Dept_Name
  RETURN
END

但是我得到了这个错误输出：

Msg 207, Level 16, State 1, Procedure Total_Salary_By_Dept, Line 18
Invalid column name 'Dept_No'.
Msg 207, Level 16, State 1, Procedure Total_Salary_By_Dept, Line 18
Invalid column name 'Dept_Name'.
Msg 207, Level 16, State 1, Procedure Total_Salary_By_Dept, Line 15
Invalid column name 'Dept_No'.
Msg 207, Level 16, State 1, Procedure Total_Salary_By_Dept, Line 15
Invalid column name 'Dept_Name'.
Msg 207, Level 16, State 1, Procedure Total_Salary_By_Dept, Line 15
Invalid column name 'Dept_No'.

我输错了什么吗？我也以正确的方式完成了我的功能吗？请给我建议！
