Here is a helper function who tells you the last SQL executed.

use DB;
public static function getLastSQL()
{
    $queries = DB::getQueryLog();
    $last_query = end($queries);
          // last_query is the SQL with with data binding like 
          //   { 
          //       select ? from sometable where field = ? and field2 = ? ;
          //       param1,
          //       param2，
          //       param3，
          //   }
          //   which is hard to read.
    $last_query = bindDataToQuery($last_query);     
          // here, last_query is the last SQL you have executed as normal SQL
          //     select param1 from sometable where field=param2 and field2 = param3;
    return $last_query
}

Here is the bindDataToQuery function, who fill the '?' blanks with real params.

protected static function bindDataToQuery($queryItem){
    $query = $queryItem['query'];
    $bindings = $queryItem['bindings'];
    $arr = explode('?',$query);
    $res = '';
    foreach($arr as $idx => $ele){
        if($idx < count($arr) - 1){
            $res = $res.$ele."'".$bindings[$idx]."'";
        }
    }
    $res = $res.$arr[count($arr) -1];
    return $res;
}
