It is only impractical if you write the code by hand, perhaps you should generate it instead. Use the output of PRAGMA table_info(yourtablename) for the code generator to make the column list dynamic. Or create a BEFORE UPDATE trigger that takes care of it and RAISE(IGNORE,'Nothing to do') when there's nothing to do. -- Groet, Cordialement, Pozdrawiam, Regards, Kees Nuyt _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
