Need To Copy All Oracle Tables To SQL Server 2005

I am racking my brain on this one. I am migrating Oracle data to SQL Server and would like an SSIS package that will copy the oracle data from every table to SQL server. I already have the schema set up in SQL and a straight copy of a specified table works fine between the OLEDB source and OLEDB destination. However, when I set up a loop which sets a global variable for the table names, which are identical on both dbs, and try to set the OLEDB Source and Destination OpenRowsetVariable to the global variable, the process fails with these errors with all validation turned off:

[OLE DB Source [18]] Warning: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.

[OLE DB Source [18]] Error: Column "ID" cannot be found at the datasource.

[DTS.Pipeline] Error: component "OLE DB Source" (18) failed the pre-execute phase and returned error code 0xC0202005.

To sum up, I want to set the tables dynamically and have them infer the mappings. The names of the columns are already the exact same on each schema, and the data types are mapped accordingly. I have already verified that the names of the tables have been formatted correctly for each database. If I can't do it this way then how?
