python的MySQLdb庫基本使用介紹

MySQLdb庫

import MySQLdb

 

簡介

提供mysql的基本操做（包括建表，讀取表數據，插入數據到表）

 

數據庫操做基本步驟

 

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import MySQLdb

if __name__ == "__main__":
    # 打開數據庫鏈接
    db = MySQLdb.connect("localhost", "root", "root", "iquota", charset='utf8')

    # 使用cursor()方法獲取操做遊標
    cursor = db.cursor()

    # 查看錶
    sql_cmd="select * from app;"

    cursor.execute(sql_cmd)
    data = cursor.fetchone()
    data_all = cursor.fetchall()

    # 關閉數據庫鏈接
    db.close()

    # 讀取一行
    print data
    # 讀取所有內容
    print data_all

mysql基本讀取舉例

輸出結果
