SQL標量值函數拋出「無效對象名稱」錯誤

Question

我的SQL標值的函數下面的代碼定義：

CREATE FUNCTION CtrAmount (@Ctr_Id int) 
    RETURNS MONEY 
    AS 
    BEGIN 
     DECLARE @CtrPrice MONEY 
     SELECT @CtrPrice = SUM(amount) 
      FROM Contracts 
     WHERE contract_id = @Ctr_Id 
     RETURN(@CtrPrice) 
    END 
GO 

SELECT * FROM CtrAmount(345) 
GO 

但是，當涉及到選擇線，我得到這個錯誤：

Msg 208, Level 16, State 3, Line 14 
Invalid object name 'CtrAmount'. 

Answer 1

Int(10) - 未知類型

CREATE FUNCTION dbo.CtrAmount 
(
    @Ctr_Id INT 
) 
RETURNS MONEY 
AS 
BEGIN 
    RETURN (
     SELECT SUM(amount) 
     FROM dbo.Contracts 
     WHERE contract_id = @Ctr_Id 
    ) 
END 
GO 

SELECT dbo.CtrAmount(345) 
GO
