Prepared statements are present in kexidb API already as you know. I think you mean about using them (directly using libpq/libpqxx API, not kexidb API) for internal purposes of the driver. I'd say go for it, just consider keeping the given statement structure after the first use internally. This will add speed and simplify things. I planned to do the same for other drivers, including sqlite, long ago. -- regards / pozdrawiam, Jaroslaw Staniek Kexi & KOffice (http://www.kexi-project.org, http://www.koffice.org) KDE Libraries for MS Windows (http://windows.kde.org) http://www.linkedin.com/in/jstaniek _______________________________________________ Kexi mailing list [email protected] https://mail.kde.org/mailman/listinfo/kexi
