Thanks for the answer Tom, I did want to write varchar2(n). Is this something special in the code? Could I somehow
muck with the system catalogs and copy varchar. The object of the execise is to have one set of SQL statements for
both
Oracle and Postgres. I think it would help other people converting if we had the ability to handle Oracle table create
statements.
Thanks
