I get the same error, but I do get all the tables and many that I think are system tables. I am sure it works near perfectly with SQL Server, but I think the VFP Team lacks enough Oracle knowledge to make the Data Explorer work as well with Oracle.

>Thanks this works, however when I attempt to view the list of tables, I get an error 'The Specified Key Already Exists' then only a few tables are displayed in the table tree.
