python插入记录后获取最后一条数据的id
#!/usr/bin/python
# import MySQL module
import MySQLdb
# get user input
name = raw_input("Please enter a name: ")
# connect
conn = MySQLdb.connect(host="localhost", user="nobody", passwd="nobody", conn="qestar", unix_socket="/tmp/mysql.sock")
# create a cursor
cursor = conn.cursor()
# execute SQL statement
cursor.execute("INSERT INTO test (nama) VALUES (%s)", name)
# get ID of last inserted record
print "ID of last record is ", int(cursor.lastrowid) #最后插入行的主键ID
print "ID of inserted record is ", int(conn.insert_id()) #最新插入行的主键ID，conn.insert_id()一定要在conn.commit()之前，否则会返回0
conn.commit()
