how to make a stored procedure return a value when there are no available values

  • Here is the script for a stored procedure that i have, i want the stored procedure to return a value of 1,if it is a null or if there are no values for it to return ,

    Create PROCEDURE [dbo].[GetExtractSiteExtractFileBatchPreviousSuccessInd]

    @BatchStatusCd NVARCHAR(5)

    ,@ExtractSiteCd NVARCHAR (10)

    ,@ExtractAsOfDate DATETIME

    AS

    SELECT case when @ExtractAsOfDate = isnull(convert(varchar(10),ExtractAsOfDate,120),'1900-01-01') then 0

    when @ExtractAsOfDate <> isnull(convert(varchar(10),ExtractAsOfDate,120),'1900-01-01')then 1 else 1 end

    as ExtractSiteExtractFileBatchPreviousSuccessInd FROM ExtractSiteExtractFileBatch

    WHERE BatchStatusCd = @BatchStatusCd

    and ExtractSiteCd =@ExtractSiteCd

    AND ExtractAsOfDate = @ExtractAsOfDate

    go

    here is the exec statement for the stored procedure, i want it to return a value of 1, if the value does not exist in the sample data.

    EXEC@return_value = [dbo].[GetExtractSiteExtractFileBatchPreviousSuccessInd]

    @BatchStatusCd = N'sb',

    @ExtractSiteCd = N'CEPOK',

    @ExtractAsOfDate = N'2013-03-18 00:00:00.000'

    SELECT'Return Value' = @return_value

    GO

    below is the sample data

    SELECT '[ExtractSiteExtractFileBatchID]','[ExtractSiteCd]','[ExtractAsOfDate]','[BatchStatusCd]','[InsertedDate]','[UpdatedDate]'

    union all

    select '1442','CEPOK','2012-07-12 00:00:00.000','SB','2012-07-13 06:04:41.843','2012-07-13 07:30:29.660'

    union all

    select '1443','CFTRT','2012-07-12 00:00:00.000','SB','2012-07-13 07:30:30.077','2012-07-13 08:29:40.433'

    union all

    select '5472','CEPED','2012-07-12 00:00:00.000','SBR','2013-03-18 17:34:12.047','2013-03-18 17:34:12.047'

  • Thanks i will give it a try and let you know the results

  • i tried it still returns no value

  • klineandking (3/19/2013)


    i tried it still returns no value

    What do you mean it returns no VALUE?

    Regardless of what you have in stored proc it always return a value! By default it's 0:

    create proc p_test

    as

    select 1 as Col;

    go

    declare @ret int;

    exec @ret = p_test;

    select @ret;

    go

    And in your attachment it does return a value too!

  • Ough, I can see now!

    You need to learn and use proper terminology!

    The stored procedure you have does return an integer value (as I've pointed out in the previous post by default it's zero).

    You asked that you want your stored proc to return value of 1 when no records found, my changes made it to do exactly that.

    What you really want is to return 1 in the recordset not as value!

    You can change you proc to do so by replacing your select with following:

    Edited: refer to the next post.

  • Even shorter version:

    CREATE PROCEDURE [dbo].[GetExtractSiteExtractFileBatchPreviousSuccessInd]

    @BatchStatusCd NVARCHAR(5)

    ,@ExtractSiteCd NVARCHAR(10)

    ,@ExtractAsOfDate DATETIME

    AS

    SELECT MIN(Res) AS ExtractSiteExtractFileBatchPreviousSuccessInd

    FROM

    (

    SELECT 1 AS Res

    UNION ALL

    SELECT case when @ExtractAsOfDate = isnull(convert(varchar(10),ExtractAsOfDate,120),'1900-01-01') then 0

    else 1

    end as Res

    FROM ExtractSiteExtractFileBatch

    WHERE BatchStatusCd = @BatchStatusCd

    and ExtractSiteCd =@ExtractSiteCd

    and ExtractAsOfDate = @ExtractAsOfDate

    ) q

    GO

    Edited, so it can be used to create stored proc

  • Thanks but i want the stored procedure to reture a single column 'GetExtractSiteExtractFileBatchPreviousSuccessInd' with the value, your script would only return the result as the return value

    My last post does exactly that - it returns recordset with one column and one row.

  • can this script be re written for it to return the values as a bit datat type?

  • Yes it can. Just use CAST function.
