今日总结-python实现数据连接,完成查询数据库信息的操作
实现效果如上;
代码:
#coding=utf-8 #连接数据库测试 import pymysql #打开数据库 db = pymysql.connect(host="localhost",user="root",password="PENGsuoqun123",db="info") #使用cursor()方法获取操作游标 cur = db.cursor() #查询操作 sql = "select * from student1" try: # 执行sql语句 cur.execute(sql) results = cur.fetchall() #遍历结果 for rows in results: id = rows[0] name = rows[1] print("id: {}, name: {}".format(id,name)) except Exception as e: raise e finally: db.close()
