<div>Hallo, meine Name ist Lukas.</div>
<div>Ich spreche leider nur schlecht englisch, deshalb schriebe ich den Text auch auf deutsch und lasse ihn von Google übersetzen.</div>
<div> </div>
<div>Ich bin noch sehr neu in der Programmierung und in QGIS und habe eine wichtige Frage.</div>
<div>Es geht um folgendes.</div>
<div> </div>
<div>Ich habe einen bereits geladenen Layer. Dieser wurde nicht über die Python Console geladen.</div>
<div>Der Layer hat über 250000 Objekte.</div>
<div> </div>
<div>Über eine "for"-abfrage, bezogen auf die einzelden Attribute, kann ich ein Objekt auswählen.</div>
<div>Dieser Vorgang dauert aber bis zu 30 sekunden. Leider sehr lange.</div>
<div> </div>
<div>Über die interne Abfrage Möglichkeit in QGIS dauert es nur 1 bis 2 Sekunden.</div>
<div> </div>
<div>Kann ich eine solche Abfrage auch über die Python-Konsole starten?</div>
<div>Ohne den Layer über die Python-Konsolen zu laden?</div>
<div> </div>
<div>
<div>Vielleicht ist es mögliche eine SQL-Abfrage zu starten? Die müsste schneller gehen.</div>
<div> </div>
</div>
<div> </div>
<div>Ich brauche wirklich dringend Hilfe</div>
<div> </div>
<div>Gruß Lukas</div></div></body></html>
