python2操作mysql數據庫_例程

首先MySQLdb庫是一個第三方庫，需要使用pip安裝相關庫

pip install mysql-python

安裝成功之後進入例程

例程的主要功能是

1. 連接mysql數據庫
2. 執行相關mysql語句
3. 關閉連接

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

import MySQLdb

#數據庫連接信息
mysqlURL = "10.240.184.74"
userName = "mawenxuan"
password = "Winxuan666"
sqlName = "h67_codecoverage"

# 函數功能：連接mysql數據庫
def connectMysql():
    db = MySQLdb.connect(
        mysqlURL, 
        userName, 
        password, 
        sqlName, 
        charset='utf8' 
        )
    return db

# 函數功能：斷開mysql數據庫
def disconnectMysql(db):
    db.close()

# 函數功能：獲取遊標
def getCursor(db):
    return db.cursor()

# 函數功能：
def demo():
    # 連接數據庫
    db = connectMysql()
    cursor = getCursor(db)

    # 執行insert sql語句
    sql = "insert into xxxxxxxxxxxxxxx"
    try:
        # 執行sql語句
        cursor.execute(sql)
        # 提交到數據庫執行
        db.commit()
        print "insert success"
    except:
        # Rollback in case there is any error
        db.rollback()
        print "error"

    # 執行select sql語句（查詢得到的數據就一個）
    sql = "select xxxxxxxxxx"
    try:
        cursor.execute(sql)
        data = cursor.fetchone()
        print data
    except:
        print "Error: unable to fecth data"

    # 執行select sql語句（查詢得到的數據爲多個）
    lsFile = list()
    sql = "SELECT xxxxxxxxxxxxxxxxxxx"
    try:
        cursor.execute(sql)
        data = cursor.fetchone()
        while data != None:
            lsFile.append(os.path.join(data[0], data[1]))
            data = cursor.fetchone()
    except:
        print "Error: unable to fecth data"

    # 斷開數據庫連接
    disconnectMysql(db)
