Subject: [PATCH] =?UTF-8?q?Fix:=20Aktualisiere=20SQL-Abfragen=20in=20seque?=
 =?UTF-8?q?lize.js=20f=C3=BCr=20bessere=20Bindung?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Änderung:
- SQL-Abfragen in der Datei sequelize.js wurden aktualisiert, um die Verwendung von `bind` anstelle von `replacements` zu implementieren. Dies verbessert die Lesbarkeit und Konsistenz der Abfragen.

Diese Anpassung sorgt dafür, dass die SQL-Abfragen effizienter und sicherer ausgeführt werden.
