Problem While Fetching Data From Oracle Linked Server

Hi,

I created a linked server as follows:

EXEC sp_addlinkedserver 'OracleLinkedServer', 'Oracle', 'MSDAORA', 'fcstage'

EXEC sp_addlinkedsrvlogin 'OracleLinkedServer', false, 'SA', 'fc_stage', 'password'

Now I try firing a simple select statement

SELECT FINANCIAL_TRX_INFO_ID FROM

[OracleLinkedServer]..[FC_STAGE].[WFS_FINANCIAL_TRX_INFO]

WHERE SFS_BUSINESS_SEGMENT IS NOT NULL

But I get the following error:

OLE DB provider "MSDAORA" for linked server "OracleLinkedServer" returned message "ORA-01426: numeric overflow

".

Msg 7330, Level 16, State 2, Line 1

Cannot fetch a row from OLE DB provider "MSDAORA" for linked server "OracleLinkedServer".

This seems to be a generic error statement. Can anyone tell me where am I going wrong.

Thanks.
