国产数据库oceanBbase,达梦,金仓与mysql数据库的性能对比 六、python读mysql数据库
#coding=utf-8 import pymysql import time #测试单表插入性能 try: start_time = time.time() # 记录开始时间 connection1 = pymysql.connect(host='192.168.0.98', user='user', password='passwd', database='mysqldb',port=3306) # 操作数据库 cursor1 = connection1.cursor() # 创建一个游标 # 查询手机信息 sql = " select * from DB_TEST_T" # 执行SQL查询(假设你已经建立了数据库连接和游标) cursor1.execute(sql) # 获取查询结果 rows = cursor1.fetchall() i = 0 for row in rows: ID = row[0] end_time = time.time() # 记录结束时间 execution_time = end_time - start_time # 计算执行时间 print(f"Function execution took {execution_time} seconds") except pymysql.Error as e: print(f'错误:,{e}')
