SQL Server - Function Error for SELECT - RETURN Value
Hi ....
Here is a Function I want to build in order to return me one value which is a DateTime format ...
I got this error any Time I tried to execute it :
Msg 444, Level 16, State 3, Procedure DateInterval, Line 20
Select statements included within a function cannot return data to a client
I will make a Stored Procedure as a last alternative, but I would like to know if this is related to the fact that I am using a SELECT to get my Return Value ? Make no sense for me
Any help
ALTER FUNCTION [dbo].[DateInterval] (@Month Int, @Year Int, @Interval Int)
RETURNS DateTime
AS
BEGIN
DECLARE @MyDate DateTime
DECLARE @EOMonthDate Datetime
DECLARE @DateInterval Datetime
-- Get a date from the two Inputs @Month & @Year
SET @MyDate = CONVERT(DateTime, CONVERT(VARCHAR(4), @Year) + RIGHT('0' + CONVERT(VARCHAR(2), @Month), 2) + '01', 102)
SELECT CONVERT(VARCHAR(10),@MyDat
-- Get the latest Day-Month from the built Date
SET @EOMonthDate = (SELECT DATEADD(DAY, -1, DATEADD(MONTH, DATEDIFF(MONTH, 0, @MyDate) +1, 0)))
-- Return the Date after calculation
SET @DateInterval = (SELECT DATEADD(MM, @Interval, @EOMonthDate ))
-- Return the result of the function
RETURN @DateInterval
END

SELECT CONVERT(VARCHAR(10),@MyDat
The default behavior is to output a select statement like that to the client. In a function it can't do that.
So assign it to a variable if it's important, or remove it if it's not.
(Tested on SQL Server 2005, removing the line made it compile - but if you need it, I suggest assigning it to a variable and using it for whatever you need it for).
