Exporting Data from Oracle Tables into Text Files

Hi,

I am transferring data from Oracle tables into text files, and facing these errors.
1. i have a varaible working as an expression and my query goes into that variable and onwards that variable is passed to dataflow task, which parse the query. my query is simple saying "Select * from PLS.ABC" where PLS is my schema, but the task generates error "Opening a rowset for "Select * from PLS.ABC" failed. check that the table exists in the database.

and surely the table is there.

2. i have a foreach loop that iterates through all the table names and the table names are passed onwards to the varaible query, the dataflow task inside the foreach loop gets the variable query and will generate text files based on tablenames which i have supplied in another variable to the connectionstring property of the flatfile destination.
please tell me if it is possible or not. all the tables have different columns and i need the output in text files..

is it possible or not..........????

please solve these two problems for me

Best Regards,
