python——连接数据库
- import pymysql
-
-
- # 建立连接
- conn = pymysql.connect(host='localhost', user='root', password='flexoffice', db='pc', charset='utf8')
- # 创建链接的对象
- cur = conn.cursor()
- # sql语句
- sql1 = 'insert into student (s_id,s_name,s_brith,s_sex) values (13,"张三","1991-01-21","男")'
- sql = 'select * from student'
- # 调用对象的execute使用sql语句
- cur.execute(sql1)
- # (('01', '语文', '02'), ('02', '数学', '01'), ('03', '英语', '03'))
- cur.execute(sql)
- conn.commit()
- # 查询需要返回值用于查看。修改则无需
- emps = cur.fetchall()
- # 关闭数据库
- conn.close()
- print(emps)
