mysql_select_db("sdntweep_tweeps", $con);
mysql_query (" DELETE FROM tweeps WHERE screenname IN (SELECT LOWER (screenname) FROM non_sudanese ");

Answer 1

There’s an error in your SQL syntax:

mysql_query (" DELETE FROM tweeps WHERE screenname IN (SELECT LOWER (screenname) FROM non_sudanese ");

should be

mysql_query (" DELETE FROM tweeps WHERE screenname IN (SELECT LOWER (screenname) FROM non_sudanese )");

note the extra ).
