由于python的数据库模块有专门的数据库模块的规范,所以,其实不管使用哪种数据库的方法都大同小异的,这里就给出一段示范的代码:
#-*- encoding: gb2312 -*- import os, sys, string import MySQLdb # 连接数据库 try: conn = MySQLdb.connect(host='localhost',user='root',passwd='xxxx',db='test1') except Exception, e: print e sys.exit() # 获取cursor对象来进行操作 cursor = conn.cursor() # 创建表 sql = "create table if not exists test1(name varchar(128) primary key, age int(4))" cursor.execute(sql) # 插入数据 sql = "insert into test1(name, age) values ('%s', %d)" % ("zhaowei", 23) try: cursor.execute(sql) except Exception, e: print e sql = "insert into test1(name, age) values ('%s', %d)" % ("张三", 21) try: cursor.execute(sql) except Exception, e: print e # 插入多条 sql = "insert into test1(name, age) values (%s, %s)" val = (("李四", 24), ("王五", 25), ("洪六", 26)) try: cursor.executemany(sql, val) except Exception, e: print e #查询出数据 sql = "select * from test1" cursor.execute(sql) alldata = cursor.fetchall() # 如果有数据返回,就循环输出, alldata是有个二维的列表 if alldata: for rec in alldata: print rec[0], rec[1] cursor.close() conn.close()
