Hi all,
I am wanting to find a way to programtically retrieve the table names, column names, column specifications (length, type etc.) from an Oracle database. So maybe using an OracelDataReader or something like that. Or maybe there is some SQL that will help me achieve this.

I would like the solution in Vb.Net or C#.

Probably you dont have privileges to access dba_tab_columns.

You may try to use ALL_TAB_COLUMNS instead.
