Ah. Thanks. Can this be removed? Is it there by default? It seems inappropriate for most users. For instance, "unset": - If the field is a text field, then "unset" (NULL) will have no meaning for a user. The user can not be expected to distinguish between a NULL value and an empty string. - For other types, such as numbers and dates, clearing the entry should result in a NULL value going into the database. I should not have to explicitly choose "unset". "set to default value": - This is only useful if there is a default value specified for that field. - Usually it's OK to just use the default value for new fields. - If this is wanted sometimes, it should be optional for some fields. "reset to original value" - What does this mean actually? Is it something I can use before pressing Enter, to stop my changes being written to the database? If so, wouldn't Undo already do this? -- Murray Cumming [EMAIL PROTECTED] www.murrayc.com www.openismus.com _______________________________________________ gnome-db-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-db-list
