How to fetch the primary key value of a recently inserted row

Question

import MySQLdb

How to fetch the primary key value of a recently inserted row, in the following execution.

cursor = mysql.cursor()
cursor.execute("""INSERT INTO foos (val1,val2) VALUES (%s,%s)""", (v1, v2))

Answer 1

From the docs :

Cursor.lastrowid

This read-only attribute provides the rowid of the last modified row (most databases return a rowid only when a single INSERT operation is performed).

Answer 2

您可以在表上添加时间戳，并使用now() - interval 1 hour例如now() - interval 1 hour来获取

Answer 3

Ignacio's answer is more appropriate for the API you're using but in general.

MySQL allows you to get the ID of the most recent insert.

SELECT LAST_INSERT_ID();
