python插入记录后取得主键id的方法(cursor.lastrowid和conn.insert_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() 

cursor.lastrowid跟conn.insert_id()的结果一般情况下是一样的，最后一条记录肯定就是刚刚插入的记录。但如果是并发插入就不一样了，多线程的时候
