自动化测试查询数据库条数

在进行自动化测试中，查询数据库的条数是一种常见的数据校验操作。可以通过使用Python连接MySQL数据库，并执行相应的SQL语句来实现。以下是一个基本的代码示例：

import pymysql

# 连接数据库
hostname = '数据库的IP地址'
username = '数据库账号'
password = '数据库账号对应的密码'
database = '要连接的具体库名'
conn = pymysql.connect(host=hostname, user=username, password=password, db=database)

# 建立游标
cursor = conn.cursor()

# 执行SQL查询语句
sql = "SELECT COUNT(*) FROM 表名"
cursor.execute(sql)

# 获取查询结果
result = cursor.fetchone()
count = result<span class="em">1</span><span class="em">2</span><span class="em">3</span>
