The other tidbit Ted doesn't mention is licensing. One of the issues with using MySQL libraries is the licensing. MySQL's client libraries are GPL, not LGPL and that can have some issues (depending upon your interpretation of the license) with your own code. ODBC abstracts you from some of those licensing concerns.

Now, I'll admit right up front that ODBC isn't perfect, but for what it does, it does it well, and there is growing support for it on the Mac platform.

Anyone have samples or url's to samples of using MySQL (I'm currently

   http://mysql-cocoa.sourceforge.net/

but the link to the example files is broken and I haven't been able
to figure out the framework.  I'd like to be use MySQL API's directly
from Cocoa, but would be okay to use Cocoa bundled/linked to C++ or C
API's if someone knows how or can point me in the right direction.

I can't recommend building directly to any DBMS, because that locks you (and your customers/users) into a back-end which may not be the best next week, month, or year -- but I would recommend looking into ODBC, either through Andrew Satori's ODBCKit, wrapping Objective C around the base of C/C++ --

   http://sourceforge.net/projects/odbckit
   http://www.druware.com/products/odbckit.html

-- or through the more raw C or C++ API calls in the iODBC dylibs and
frameworks from the full (free) iODBC SDK provided by OpenLink Software
(my employers) --


   http://sourceforge.net/projects/iodbc
   http://www.iodbc.org/
   http://www.versiontracker.com/dyn/moreinfo/macosx/23969

Building to use the ODBC APIs -- especially if you use standards-
compliant SQL (rather than DBMS-specific dialects) -- can deliver an
application which can be used against any ODBC accessible DBMS, which
means end-users can use MySQL if they want, or OpenLink Virtuoso,
PostgreSQL, Oracle, Microsoft SQL Server, Sybase, Ingres, Progress,
Frontbase, Openbase, Firebird, etc. -- whatever engine suits their
overall personal or enterprise needs and goals.

Full documentation on writing ODBC applications is found in the online
ODBC Developer's Guide, hosted by Microsoft (maintainers of the spec).
This documentation is not scoped to Objective C, nor to Mac OS X, but
it covers the ODBC API in fairly exhaustive detail.

Be seeing you,

Ted
