Ja, klar.

Hier die Ausgabe des EXPLAIN: 

+----+-------------+----------------------------+------+-----------------+-----------------+---------+-------+---------+-----------------------------+
| id | select_type | table                      | type | possible_keys   | key             | key_len | ref   | rows    | Extra                       |
+----+-------------+----------------------------+------+-----------------+-----------------+---------+-------+---------+-----------------------------+
|  1 | SIMPLE      | highscores                 | ref  | idx_spielmodus  | idx_spielmodus  | 5       | const | 1230952 | Using where; Using filesort |
+----+-------------+----------------------------+------+-----------------+-----------------+---------+-------+---------+-----------------------------+

Die beiden Indizes hab ich schon wieder weggeschmissen.


Danke und Gruß,

Tobias.
