# 导入mysql驱动
import pymysql
#password和user是自己数据库的名字和密码，view是创建好的数据库
conn = pymysql.connect(user='root', password='123456', database='view')

cursor = conn.cursor()
# 创建user表
cursor.execute('create table user (id VARCHAR(20) PRIMARY KEY , NAME VARCHAR(20))')
# 插入一行记录，注意MySQL的占位符是%s:
cursor.execute('insert into USER(id,NAME ) VALUE (%s,%s)', ('1','jiajikang'))
print('rouwcount(行数):', cursor.rowcount)
# 提交事务:
conn.commit()
cursor.close()

# 运行查询:
cursor = conn.cursor()
cursor.execute('select * from user WHERE id = %s', ('1',))
values = cursor.fetchall()
print(values)
# 关闭Cursor和Connection:
cursor.close()
conn.close()
