SQL関数で2つのクエリを追加する

Question

私は以下のような関数を作成しようとしていますが、基本的に2つの金額を照会し、それらを合計して結果を返す必要があります。それは可能ですか？

おかげ

CREATE function [dbo].[fn_manualpricing2-NEW](@type varchar(50),@capid int,@milespa int, @maintained bit, @term int, @product varchar(50), @funder varchar(50)) 
returns money 
as 
BEGIN 

RETURN (
SELECT TOP 1 price FROM tblPricing WHERE [type]=@type AND term=@term AND milespa=@milespa AND capid=@capid AND maintained=@maintained AND source=@funder and product=@product ORDER BY price 
+ 
SELECT TOP 1 addonpricevalue FROM [dbWebsiteLO3-PRICING].[dbo].[AddonPrices] WHERE VehicleType=1 AND term=@term AND miles=@milespa AND source=@funder 
) 
END 

GO 

Answer 1

は次のように試してみてください。..

CREATE function [dbo].[fn_manualpricing2-NEW](@type varchar(50),@capid int,@milespa int, @maintained bit, @term int, @product varchar(50), @funder varchar(50)) 
returns money 
as 
BEGIN 

DECLARE @variable money 
SET @variable = (SELECT TOP 1 price FROM tblPricing WHERE [type]=@type AND term=@term AND milespa=@milespa AND capid=@capid AND maintained=@maintained AND source=@funder and product=@product ORDER BY price) 
+ 
(SELECT TOP 1 addonpricevalue FROM [dbWebsiteLO3-PRICING].[dbo].[AddonPrices] WHERE VehicleType=1 AND term=@term AND miles=@milespa AND source=@funder) 

return @variable 

END 

GO

これは、少ないコードで行うことができますが、これはあなたの一般的なアイデアを与える：

CREATE FUNCTION dbo.ufn_AddTwoValues() 
RETURNS Money 
WITH EXECUTE AS CALLER 
AS 
-- place the body of the function here 
BEGIN 
    DECLARE @ValOne money; 
    DECLARE @ValTwo money; 
    DECLARE @Result money; 

    SET @ValOne = (SELECT 1); 
    SET @ValTwo = (SELECT 2); 

    SET @Result = @ValOne + @ValTwo; 

    RETURN @Result; 
END 
GO 

select dbo.ufn_AddTwoValues()
