Hello all.
My data source is an Excel file. In my Data Flow Task, I am using a value from the Excel data to perform a look-up using a query to an Oracle database. Currently, about half the look-up's fail.
When I redirect the No Match Output to a flat file and query the Oracle table(s) using keys from this file directly (using TOAD), the data is there.
The datatype of the key in the Oracle table(s) is VARCHAR2(20), the input data from the Excel file is converted to (DT_WSTR,20). This is 32-bit SSIS 2012 on Windows 7 and an Oracle 8i database.
I cannot figure out why some look-up's fail while others do not when the key is there in both cases. Any ideas?
