自动化测试22

python操作mysql数据库需要使用到mysqlclient库。

安装:pip install mysqlclient

python连接mysql数据库分以下步骤:

1、与mysql建立连接;

2、获取游标;

3、执行sql语句;

4、fetch查询结果或commit修改结果;

5、关闭游标;

6、关闭mysql连接。

 

完整示例如下:

 

# -*- coding:utf-8 -*-
import MySQLdb
from readConfig import get_config_values
from utils.resutltodict import dict_fetchall


def execute_sql_query(sql, params):
    """
    执行mysql sql查询语句
    :param sql: sql语句,变量使用%s占位
    :param params: %s对应的变量,必须是元祖(tuple)
    :return: queryset
    """
    conn = MySQLdb.connect(host=get_config_values('mysql', 'host'), port=int(get_config_values('mysql', 'port')),
                       user=get_config_values('mysql', 'user'), passwd=get_config_values('mysql', 'password'),
                       db=get_config_values('mysql', 'database'), charset='utf8')
    cursor = conn.cursor()
    cursor.execute(sql, params)
    qryset = dict_fetchall(cursor=cursor)
    cursor.close()
    conn.close()
    return qryset


if __name__ == '__main__':
    sql = """SELECT * FROM asset_devices where companyid_id=%s"""
    params = (25,)
    result = execute_sql_query(sql=sql, params=params)
    print(result)
