<TD colspan="3">Welcome to a short tutorial on ODBC programming. The goal of this tutorial is
to introduce a C-Programmer to ODBC programming. During this tutorial we will
code a simple program which connects to a database via ODBC and reads some data.
There won't be any information on how to program ODBC Drivers or about <EM>unixODBC</EM>
internals. Configuration won't be covered too.
The program developed throughout this tutorial was originally coded under WinNT
and later ported without any adjustments to Linux and <EM>unixODBC</EM>. This is
how compatibility should work :)
<P>
The information given within this tutorial are brief at best. Please
take it as a pointer where and how to start.
