python操作mysql 比较两个数据是否相等

你可以使用SQL的比较操作符（=）来比较两个数据是否相等。在Python中使用 MySQL Connector模块来连接MySQL数据库，然后执行查询语句来比较这两个数据是否相等。下面是一个示例代码：

import mysql.connector

mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
password="yourpassword",
database="mydatabase"
)

mycursor = mydb.cursor()

sql = "SELECT * FROM customers WHERE name = %s AND address = %s"
val = ("John", "Highway 21")
mycursor.execute(sql, val)

myresult = mycursor.fetchall()

if len(myresult) > 0:
print("These two records are equal")
else:
print("These two records are not equal")
