<p>Mit mysql_query() sendet man eine SQL-Anfrage (Anfrage) an einen<br>

Datenbankserver. Wird der optionale Parameter der Verbindungskennung<br>

(Verbindungs-Kennung) nicht angegeben, so wird versucht, eine Verbindung<br>

ohne Angaben von Argumenten (siehe mysql_connect) aufzubauen.<br>

Die Funktion mysql_query() liefert im Erfolgsfall true, sonst false zurück.<br>
