duplicate reference key values

HI, I keep getting this warning with a lookup (full cache mode) that retreives data form a table that contains the following information:

SRCE_SYS TABLE_NAME FIELD_NAME CODE ENGLISH_DESCRIPTION
STATIC STATIC PM_PC_TX_TYPE_CODE G GROSS
STATIC STATIC PM_PC_TX_TYPE_CODE E EXCESS
STATIC STATIC PM_PC_TX_TYPE_CODE F FACULTATIVE
STATIC STATIC PM_PC_TX_TYPE_CODE S SURPLUS
STATIC STATIC PM_PC_TX_RIDER_CODE BOAT BOAT
STATIC STATIC PM_PC_TX_RIDER_CODE RIDER RIDER
STATIC STATIC PM_PC_TX_RIDER_CODE CONT CONTENTS

The column tab matches SRCR_SYS, TABLE_NAME and FIELD_NAME (using constants defined in a derived column transform) .The code column comes from the source. We want to retreive the english_description colum from SRCR_SYS, TABLE_NAME,FIELD_NAME and CODE in the dataflow.

I would normally ignore the warning but sometimes, it seems that the lookup does not match any values and enabling memory restriction on the advanced tab resolve the issue and suppress the warning.

As I said, I keep getting this warning and I don't know why since there are no duplicates in the table? Am I missing something?

Thank you,

Christian

For the three fields SRCR_SYS, TABLE_NAME, and FIELD_NAME, there are duplicate keys.

You aren't matching on CODE as well?|||

Yes, I match the code as well so the combination of all 4 columns is unique. Does SSIS looks for all columns that are matched in the column tab or just the first one?

Thanks,

Christian

|||It matches on all columns that you select as lookup columns.

The following query should identify any duplicates:
select srce_sys,table_name,field_name,code,count(*) from table group by srce_sys,table_name,field_name,code having count(*)>1

DTS/SSIS too many tables warning and subsequent error

I need to bring over a large number of tables' records (200+ tables) with the Import/Export Wizard. The tables are being imported from MS Access. A separate script run previously will create the tables, so the DTS wizard is only to bring over the data from the Access tables into the empty SQL ones.

First, I get the warning that indicates "a large number of tables are selected for copying, and the wizard may not be able to copy all the tables in a session. Select no to go back and unselect some tables, or select Yes to attempt to copy all the currently selected tables at one time".

Well, I proceed with the DTS and it tries to validate and takes a fair bit, but then it errors indicating:

"Error 0xc0202009: {2F0FABA0-5F4B-4310-97C0-76EA19893547}: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Unspecified error".
(SQL Server Import and Export Wizard)"

Can anyone shed any light on why I receive an "unspecified error" when tring to DTS a larger number of tables. It does not error, if I import 40 or so tables.

This was never an issue with SQL 2000 DTS.

Thanks

"a large number of tables are selected for copying, and the wizard may not be able to copy all the tables in a session. Select no to go back and unselect some tables, or select Yes to attempt to copy all the currently selected tables at one time".

The wizard told you that it may not be able to do it.

Hey,

Hah! Nice man. Well I hear you on that one, but why is this an issue with the SQL 2005 DTS and not the older SQL 2000 DTS, and is there any way around it?

Thanks
