I'm currently using unixODBC to get started and hope to be able to preserve source code compatibility with MS's ODBC Driver Manager (and eventually iODBC if needed). If there are bugs in the platform code then these will bother me not before some time from now because I'm still wrapping all (or rather a subset of) those SQL... functions which live in sql[ext].h. Currently my own refcount leaks are much worse than any driver manager's memory leaks could ever be ;-). cheers, andreas _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
