SSIS is skipping random rows

Hi Guys,

I am transferring 1000 rows from a SQL Data Source to SQL Destination using OLEDB Command control. I am using OLEDB Command because i need to execute the stored procedure for each row.
I have found that 974 rows were transferred. I figured out which rows were skipped and then executed stored procedure manually to see if any errors but manually stored procedure ran successfully and it inserted those records.

I have also created a flow task to include only those records which missed during the first load
SELECT TOP ( 1000 )
        AddressStringId ,
        HASHBYTES('SHA1', CONVERT(VARCHAR(12), AddressStringId)) AS Guid ,
        HASHBYTES('SHA1', SearchString) AS UniqueHashString ,
        OrganisationName AS LocationName ,
        OrganisationName AS AddressLine1 ,
        SubBuildingName AS AddressLine2 ,
        '' AS AddressLine3 ,
        BuildingNumber ,
        BuildingName ,
        StreetFirstPart + ' ' + StreetSecondPart AS Street ,
        '' AS Locality ,
        'England' AS AdministrativeArea ,
        '' AS SubAdministrativeArea ,
        PostTown AS Municipality ,
        PostCode ,
        'GB' AS Iso3166MinusOneCountryAlpha2Code ,
        STR(Longitude, 25, 5) AS Longitude ,
        STR(Latitude, 25, 5) Latitude ,
        SearchString ,
        3.0 AS PointBufferDistanceInMeters ,
		--below are the output parameters in the stored procedure however SSIS doesn't seem to handle this. so passing 0 or null values for these parameters
        ISNULL(ERROR_NUMBER(), 0) AS ErrorNumber ,
        ISNULL(ERROR_SEVERITY(), 0) AS ErrorSeverity ,
        ISNULL(ERROR_STATE(), 0) AS ErrorState ,
        ISNULL(ERROR_PROCEDURE(), 0) AS ErrorProcedure ,
        ISNULL(ERROR_LINE(), 0) AS ErrorLine ,
        ISNULL(ERROR_MESSAGE(), '') AS ErrorMessage ,
        0 AS InsertedRecords
FROM    AddressStringSearch
WHERE AddressStringId IN (16855935,16855951,16856022,16856056,16856155,16856162,16856207,16856243,16856257,16856301,16856362,16856406,16856430,16856444,16856453,16856453,16856491,16856585
,16856602,16856623,16856650,16856680,16856687,16856701,16856703,16856758,16856809)

Open in new window


The task ran successfully without any error but no records got transferred.
That's how i manually executed the stored procedure
USE [Spaces]
GO

DECLARE	@return_value int,
		@ErrorNumber int,
		@ErrorSeverity int,
		@ErrorState int,
		@ErrorProcedure nvarchar(128),
		@ErrorLine int,
		@ErrorMessage nvarchar(4000),
		@NumberOfInsertedLocations INT
        
				DECLARE @Wgs84Longitude1 AS FLOAT =CAST(LTRIM(RTRIM('                 -2.15637')) AS FLOAT)
		DECLARE @Wgs84Latitude1 AS FLOAT =  CAST(LTRIM(RTRIM('                 57.26038')) AS FLOAT)

EXEC	@return_value = [CrossContext].[USP_Locations_AddPointLocations]
		@LocationGuid = 0x9F24EC0E32CD4ED6FC96B737D9CBD8FD4DFEA8E2,
		@AddressStringId=16855951,
		@LocationName = N'',
		@AddressLine1 = N'',
		@AddressLine2 = N'',
		@AddressLine3 = N'',
		@BuildingNumbers = N'10',
		@BuildingName = N'',
		@Street = N'BROOMHILL WAY',
		@Locality = N'',
		@Municipality = N'ABERDEEN',
		@AdministrativeArea = N'England',
		@SubAdministrativeArea = N'',
		@PostalCode = N'AB21 0AA',
		@Iso3166MinusOneCountryAlpha2Code = N'GB',
		@Wgs84Longitude =@Wgs84Longitude1,
		@Wgs84Latitude =  @Wgs84Latitude1,
		@PointBufferDistanceInMeters = 3.0,
		@UniqueHashString = N'0xC6566F541E3CC5B2066541379CCA27F9EB522901',
		@ErrorNumber = @ErrorNumber OUTPUT,
		@ErrorSeverity = @ErrorSeverity OUTPUT,
		@ErrorState = @ErrorState OUTPUT,
		@ErrorProcedure = @ErrorProcedure OUTPUT,
		@ErrorLine = @ErrorLine OUTPUT,
		@ErrorMessage = @ErrorMessage OUTPUT,
		@NumberOfInsertedLocations = @NumberOfInsertedLocations OUTPUT

SELECT	@ErrorNumber as N'@ErrorNumber',
		@ErrorSeverity as N'@ErrorSeverity',
		@ErrorState as N'@ErrorState',
		@ErrorProcedure as N'@ErrorProcedure',
		@ErrorLine as N'@ErrorLine',
		@ErrorMessage as N'@ErrorMessage',
		@NumberOfInsertedLocations as N'@NumberOfInsertedLocations'

SELECT	'Return Value' = @return_value

GO

I manually passed the values for two Ids 16855935 and 16855951. The stored procedure ran fine.
Now i am totally confused as why is it happening can you please help?

In clause doesn't work if you have NULL in the table.

I think below is the issue.

WHERE AddressStringId IN (16855935,16855951,16856022,16856056,16856155,16856162,16856207,16856243,16856257,16856301,16856362,16856406,16856430,16856444,16856453,16856453,16856491,16856585
,16856602,16856623,16856650,16856680,16856687,16856701,16856703,16856758,16856809)

I don't have null values in my table. all of these id's do exist. Also these ids were skipped from the initial load and i can add them by running stored procedure manually as explained in my original question

it is the same query without where clause in it

SELECT TOP ( 1000 )
        AddressStringId ,
        HASHBYTES('SHA1', CONVERT(VARCHAR(12), AddressStringId)) AS Guid ,
        HASHBYTES('SHA1', SearchString) AS UniqueHashString ,
        OrganisationName AS LocationName ,
        OrganisationName AS AddressLine1 ,
        SubBuildingName AS AddressLine2 ,
        '' AS AddressLine3 ,
        BuildingNumber ,
        BuildingName ,
        StreetFirstPart + ' ' + StreetSecondPart AS Street ,
        '' AS Locality ,
        'England' AS AdministrativeArea ,
        '' AS SubAdministrativeArea ,
        PostTown AS Municipality ,
        PostCode ,
        'GB' AS Iso3166MinusOneCountryAlpha2Code ,
        STR(Longitude, 25, 5) AS Longitude ,
        STR(Latitude, 25, 5) Latitude ,
        SearchString ,
        3.0 AS PointBufferDistanceInMeters ,
		--below are the output parameters in the stored procedure however SSIS doesn't seem to handle this. so passing 0 or null values for these parameters

Have you defined batch size or something like that ... Query seems to be fine.

no i have not defined anything perhaps using default settings for Data Source, and OLEDB Command component. The only thing i am using is Data Conversion component to convert some fields to unicode string.
The AMAZING thing is that i could not find any difference between inserted and skipped records. Also the strange is that i can manually execute the stored procedure which successfully operates. There must be something with OLEDB command control

Ok, Try this approach.

Create a sp and perform everything from there and see if any row is missed or not.

If not you can continue with the above approach. If not then we shall look into the SSIS code.

Thanks a lot. It did help. For some reasons stored procedure worked instead of normal select clause
