I am having a similar problem as the indivudual that posted this post:
SSIS - DataReader Source with ODBC Oracle RDB.

I have DTS package that I am converting to SSIS. In this package I am trying
to read from an Oracle RDB database with a simple select statement. I have
the newest driver provided by Oracle and I can get numerical data ok.
Character data is an issue. I have been reading on the net and it seems like
Microsoft is wanting you to get a driver from a Third Part to make this work
Is this the case? Any help or feedback would be appreciated on this.

Thanks in advance,

Michael
