Verwenden Sie keine gelöschten Primärschlüssel
ID 1 und 2 einfügen. ID 2 entfernen. Neue Zeile einfügen, statt 3 wird ID 2 angezeigt. Wie ändere ich das? Ich möchte Primärschlüssel nicht wiederverwenden.
import sqlite3, os
os.remove('mydatabase.db')
conn = sqlite3.connect("mydatabase.db") # or use :memory: to put it in RAM
cursor = conn.cursor()
# create a table
cursor.execute("CREATE TABLE if not exists albums (id INTEGER PRIMARY KEY NOT NULL, title text, artist text, release_date text, publisher text, media_type text)")
cursor.execute("CREATE TABLE if not exists anti (id INTEGER, title text, artist text, release_date text, publisher text, media_type text)")
conn.commit()
cursor.execute("INSERT INTO albums VALUES (null, 'Glow', 'Andy Hunter', '7/24/2012', 'Xplore Records', 'MP3')")
