SQL函数调用

函数如下
CREATE FUNCTION StockBalance_AmountIn(@SortID int)  
 RETURNS numeric(18,4)
AS  
BEGIN 
 Declare @dblReturn numeric(18,4)
 Select @dblReturn = SUM(AmountCurrentMonthIn) from AT_Materiel_StockBalance Where SortID = @SortID
 Return (@dblReturn)
END
调用方法
select dbo.StockBalance_AmountIn(2523)
这里头需要加dbo
