Question

Select statements included within a function cannot return data to a client.

Asked by: globalhealthcouncil

It is saying that: Select statements included within a function cannot return data to a client., but I want to use the Case to determine if specific types of records qualify.  Not all records need the extra criteria in the Where clause, just specific types.

How can I do this without creating a returning value?

USE [APTIFY]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[fnGHCGetOrderBalanceAsOf] (
    @AsOfDate DATETIME,
    @OrderID INT,
    @OrderGrandTotal MONEY)
 
RETURNS MONEY AS
 
BEGIN
 
    DECLARE @PayAmount MONEY
    SELECT ISNULL(SUM(pd.Amount),0) as PaiedAmount
        FROM PaymentDetail pd
           RIGHT OUTER JOIN Payment p ON pd.PaymentID = p.ID
            INNER JOIN paymentauthorization pa On pa.PaymentID = p.id
			INNER JOIN paymentinformation pim on p.Paymentinformationid = pim.id 
        WHERE pd.OrderID = @OrderID
        AND p.EffectiveDate <=@AsOfDate
		AND (Case when pim.PaymentTypeID NOT in (2,3,4) then 'Capture' else pa.AuthorizationType end)  = 'Capture'
 
    RETURN (@OrderGrandTotal - @PayAmount)
END

I believe this is as simple as changing your select statement line to:

SELECT @PayAmount = ISNULL(SUM(pd.Amount),0)

 

by: globalhealthcouncilPosted on 2009-09-17 at 11:21:46ID: 25359253

That is how I had it to begin with and it still is trying to return a value to the user.

 

by: jeflabaPosted on 2009-09-17 at 11:46:54ID: 25359537

Once you change it back to the SELECT @PayAmount = = ISNULL(SUM(pd.Amount),0) line then
try (temporarily) commenting out the two lines beginning AND (Case... line and see if the syntax checker still hiccups.

When I retired the first suggestion and then walked through as expected I found the function was then working correctly.  Then I discovered the calling stored procedure was passing a value to the function that was no longer needed. So both were the cause of the error.

Thanks for the lead to the solution.

Ok.  The attached passed the syntax checker on my system.  Are you using SQL Enterprise Manager or just creating the function from TSQL?

Create FUNCTION [dbo].[fnGHCGetOrderBalanceAsOf] (
    @AsOfDate DATETIME,
    @OrderID INT,
    @OrderGrandTotal MONEY)
 
RETURNS MONEY AS
 
BEGIN
 
    DECLARE @PayAmount MONEY
    SELECT @PayAmount = ISNULL(SUM(pd.Amount),0)
        FROM PaymentDetail pd
           RIGHT OUTER JOIN Payment p ON pd.PaymentID = p.ID
            INNER JOIN paymentauthorization pa On pa.PaymentID = p.id
                        INNER JOIN paymentinformation pim on p.Paymentinformationid = pim.id 
        WHERE pd.OrderID = @OrderID
        AND p.EffectiveDate <=@AsOfDate
                AND (Case when pim.PaymentTypeID NOT in (2,3,4) then 'Capture' else pa.AuthorizationType end)  = 'Capture'
 
    RETURN (@OrderGrandTotal - @PayAmount)
END
