[mysql] How do I get the “id” after INSERT into database with Python?

滿實用的，取流水號（identity）的方法。

Also, cursor.lastrowid (a dbapi/PEP249 extension supported by MySQLdb):

>>> import MySQLdb
>>> connection = MySQLdb.connect(user='root')
>>> cursor = connection.cursor()
>>> cursor.execute('INSERT INTO sometable VALUES (...)')
1L
>>> connection.insert_id()
3L
>>> cursor.lastrowid
3L
>>> cursor.execute('SELECT last_insert_id()')
1L
>>> cursor.fetchone()
(3L,)
>>> cursor.execute('select @@identity')
1L
>>> cursor.fetchone()
(3L,)

如果 python3 無法使用 MySQLdb 參考這篇：Python 連 mysql
