select * from dummy where concat_ws (',', id, roll_no) not in ('1,111', '2,222')
Komplett lösning:
$tableName = "test";
$fields = array( "id" , "roll_no" );
$values = array( "1,111", "2,222" );
$fieldsStr = implode(',', $fields);
$valuesStr = implode("','", $values);
$sql = "SELECT *
FROM $tableName
WHERE concat_ws(',', $fieldsStr ) NOT IN ( '$valuesStr' )";
