Python之MySql操作

1.安装驱动

输入命令：pip install MySQL-python

2.直接使用驱动

#coding=utf-8
import MySQLdb
conn= MySQLdb.connect(
        host=‘127.0.0.1‘,
        port = 3306,
        user=‘root‘,
        passwd=‘root‘,
        db =‘数据库名称‘,
         charset=‘utf8‘
        )
cur = conn.cursor()
aa=cur.execute("select * from 表名")
print aa

3.ORM框架——SQLAlchemy

输入命令：pip install Flask-SQLAlchemy

快速入门：http://www.pythondoc.com/flask-sqlalchemy/quickstart.html

from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config[‘SQLALCHEMY_DATABASE_URI‘] = ‘mysql://root:[email protected]/test‘#
app.config.setdefault(‘SQLALCHEMY_TRACK_MODIFICATIONS‘, True)
db = SQLAlchemy(app)

class User(db.Model):
    ID = db.Column(db.Integer, primary_key=True)
    Name = db.Column(db.String)
    Age = db.Column(db.Integer)

def __init__(self,Name,Age):
        self.Name = Name
        self.Age = Age

inset=User(Name=‘cnki‘,Age=25)
db.session.add(inset)
db.session.commit()
