不要使用已删除的主键

Question

插入id 1和2.删除id 2.插入新行，它会得到id 2而不是3.如何更改此？我不想重用主键。

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')") 
cursor.execute("INSERT INTO albums VALUES (null, 'second', 'artist', '7/24/2012', 'Xplore Records', 'MP3')") 
conn.commit() 

cursor.execute("SELECT * FROM albums") 
print(cursor.fetchall()) 

cursor.execute("INSERT INTO anti SELECT * FROM albums WHERE title='second'") 
cursor.execute("DELETE FROM albums WHERE title='second'") 
cursor.execute("INSERT INTO albums VALUES (null, 'third', 'artist', '7/24/2012', 'Xplore Records', 'MP3')") 
conn.commit() 

cursor.execute("SELECT * FROM albums") 
print(cursor.fetchall()) 
cursor.execute("SELECT * FROM anti") 
print(cursor.fetchall())

从https://www.sqlite.org/autoinc.html：

如果出现AUTOINCREMENT关键字后INTEGER PRIMARY KEY，改变了自动ROWID分配算法，以防止的ROWID的再利用对数据库的寿命。换句话说，AUTOINCREMENT的目的是防止重复使用以前删除的行中的ROWID。
