之前都是在mysql的存储过程中插入数据,毕竟mysql语法函数有限,很多都有限制。突然想到学了python正好可以练练手。
首先需要安装pymysql模块包(模块包安装请自行百度)
1 #encoding:utf-8 2 import pymysql 3 import time 4 import random 5 #连接mysql 6 db = pymysql.connect('14.29.249.74','kx_admin','Yjh7yC0L7L1G1k6qXKwb','ilock') 7 #获取mysql操作光标 8 cursor = db.cursor() 9 #初始化变量 10 count = 0 11 #设置sql语句循环次数 12 while count <= 100: 13 count += 1 14 #定义mysql字段的范围随机数变量 15 num = random.randint(0,2) 16 memo_num = random.randint(100,111) 17 city_list = ['长沙','湘潭','株洲','衡阳'] 18 a = random.choice(city_list) 19 #生成mysql语句插入语句 20 sql = "insert into iodn_city(city_code,city_name,memo)values(%s,'%s',%s)" %(num,a,memo_num) 21 #执行sql语句 22 try: 23 cursor.execute(sql) 24 db.commit() 25 #错误回滚 26 except: 27 db.rollback() 28 #关闭mysql 29 db.close()
