Please find attached a new gda_parse_string convenient function. I'm using in some code and I think any buddy needs to parse a SQL command string and get its parameters all the time, this function helps on it. -- Trabajar, la mejor arma para tu superación "de grano en grano, se hace la arena" (R) (en trámite, pero para los cuates: LIBRE) _______________________________________________ gnome-db-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-db-list
