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

所谓覅破解

• #!/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
