    Welcome to the Monastery!

    We can help you if you give us more information on what interface you are using (DBD::Sybase, ODBC, JDBC ) ?, as well as which specific tutorial code you tried (please post relevant lines), and what errors it fails with.

    Please review How do I post a question effectively?.
