Hi, I'm a student and I am new to cocoa programming. For a

this, but I can't imagine it's all that difficult. Any help would
be greatly appreciated. Thank you.
Brian,
I've not had an opportunity to do any ODBC programming, but I have
used Google. :-)
Mac OS X ships with the IODBC libraries in /usr/lib, headers in /
usr/include.
Take a look at <http://www.iodbc.org/index.php?page=docs/
macosodbcstory/index> for more info on using them on Mac OS X.
This might also be useful: <<http://docs.openlinksw.com/st/

I don't believe there is a native Cocoa API, but you can call into
the iODBC C libraries from Cocoa code without any trickiness.
Objective-C is C with extensions to enable object-oriented
programming. If you're not new to C, you'll already know how to
use C libraries in Cocoa; it's the same as using them from C or C++.

Please forgive me as I am new to both Cocoa and databases. I am
running firebird database. So through terminal, I use:
$ isql
Use CONNECT or CREATE DATABASE to specify a database
SQL> connect 'DbPATH' user UID password PASSWD;
to connect to my database. So in my project, in the class that is
responsible for accessing the database, i have #include <isqlext.h>
(which calls isql.h and iodbcunix.h) in the header and implementation
files. So if I use DbConn(db, UID, PASSWD), my app crashes.... which
tells me that this is not the right command or I need to include more
files. So my question has now evolved into how do I use obj-C to
communicate with my database? Is there any documentation on how to
accomplish this or has anyone had experience with this? Thanks for
the help and for your patience!
