How to pass multiple values to single parameter in stored procedure

Question

I'm using SSRS for reporting and executing a stored procedure to generate the data for my reports

DECLARE @return_value int

EXEC    @return_value = [dbo].[MYREPORT]
        @ComparePeriod = 'Daily',
        @OverrideCompareDate = NULL,
        @PortfolioId = '5,6',
        @OverrideStartDate = NULL,
        @NewPositionsOnly = NULL,
        @SourceID = 13

SELECT  'Return Value' = @return_value

GO

In the above when I passed @PortfolioId = '5,6' it is giving me wrong inputs

I need all records for portfolio id 5 and 6 also is this correct way to send the multiple values ?

When I execute my reports only giving @PortfolioId = '5' it is giving me 120 records and when I execute it by giving @PortfolioId = '6' it is giving me 70 records

So when I will give @PortfolioId = '5,6' it should have to give me only 190 records altogether, but it is giving me more no of records I don't understand where I exactly go wrong .

Could anyone help me? thanks

all code is too huge to paste , i'm pasting relevant code please suggest clue.

CREATE PROCEDURE [dbo].[GENERATE_REPORT]
(
    @ComparePeriod VARCHAR(10),
    @OverrideCompareDate DATETIME,
    @PortfolioId VARCHAR(50) = '2',   --this must be multiple 
    @OverrideStartDate DATETIME = NULL,
    @NewPositionsOnly BIT = 0,
    @SourceID INT = NULL

)  AS
BEGIN   
SELECT  
            Position.Date,
            Position.SecurityId,
            Position.Level1Industry,
            Position.MoodyFacilityRating, 
            Position.SPFacilityRating, 
            Position.CompositeFacilityRating, 
            Position.SecurityType,
            Position.FacilityType,
            Position.Position

        FROM
            Fireball_Reporting.dbo.Reporting_DailyNAV_Pricing POSITION WITH (NOLOCK, READUNCOMMITTED)
         LEFT JOIN Fireball.dbo.AdditionalSecurityPrice ClosingPrice WITH (NOLOCK, READUNCOMMITTED) ON
                    ClosingPrice.SecurityID = Position.PricingSecurityID AND
                    ClosingPrice.Date = Position.Date AND
                    ClosingPrice.SecurityPriceSourceID = @SourceID AND
                    ClosingPrice.PortfolioID IN (
                SELECT
                PARAM
                FROM
                Fireball_Reporting.dbo.ParseMultiValuedParameter(@PortfolioId, ',')                                             )

Answer 1

USE THIS

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

I hope this helps people because it was exactly what I was looking for

Answer 2

This can not be done easily. There's no way to make an NVARCHAR parameter take "more than one value". What I've done before is - as you do already - make the parameter value like a list with comma-separated values. Then, split this string up into its parts in the stored procedure.

Splitting up can be done using string functions. Add every part to a temporary table. Pseudo-code for this could be:

CREATE TABLE #TempTable (ID INT)
WHILE LEN(@PortfolioID) > 0
BEGIN
    IF NOT <@PortfolioID contains Comma>
    BEGIN
        INSERT INTO #TempTable VALUES CAST(@PortfolioID as INT)
        SET @PortfolioID = ''
    END ELSE
    BEGIN
         INSERT INTO #Temptable VALUES CAST(<Part until next comma> AS INT)
         SET @PortfolioID = <Everything after the next comma>
    END
END

Then, change your condition to

WHERE PortfolioId IN (SELECT ID FROM #TempTable)

EDIT
You may be interested in the documentation for multi value parameters in SSRS, which states:

You can define a multivalue parameter for any report parameter that you create. However, if you want to pass multiple parameter values back to a data source by using the query, the following requirements must be satisfied:

The data source must be SQL Server, Oracle, Analysis Services, SAP BI NetWeaver, or Hyperion Essbase.

The data source cannot be a stored procedure. Reporting Services does not support passing a multivalue parameter array to a stored procedure.

The query must use an IN clause to specify the parameter.

This I found here.

Answer 3

I spent time finding a proper way. This may be useful for others.

Create a UDF and refer in the query -
