数据库相关

关于批量执行SQL语句

在数据库应用中，一般我们是用企业管理器来创建数据库，表，存储过程，触发器等。然后再导出SQL语句到一个*.sql文件里。然后我们在查询分析器执行这些语句即可。当然，我们更想在程序中去执行这些语句，而不是再去打开查询分析器。当我们要在程序中批量执行SQL时，需要明白AdoConnection，或AdoQuery（假设我们使用ADO组件）可以执行的语句有什么要求。1、在查询分析器里，一条SQL语句，我们可以直接写成Select*fromaTablewhereI

Oracle

Oracle体系结构简介

1.ORACLE简介Oracle数据库管理系统是一个以关系型和面向对象为中心管理数据的数据库管理软件系统，其在管理信息系统、企业数据处理、因特网及电子商务等领域有着非常广泛的应用。因其在数据安全性与数据完整性控制方面的优越性能，以及跨操作系统、跨硬件平台的数据互操作能力，使得越来越多的用户将Oracle作为其应用数据的处理系统。Oracle数据库是基于“客户端／服务器”（Client/Server）模式结构。客户端应用程序执行与用户进行交互的活动。其接收用

编程技术

以一种"廉价"的方式获取页面的标题(downmoon)

有朋友问到：“我需要得到一个webpage的title，因为这个title一般都比较靠前，只要取得html的前面少量内容就可以了。因为要取得很多个页面的title,如果下载整个htmlcode，肯定比较浪费时间。.net好像没有现成的类可以干这件事情(取得部分html)，我应该如何去实现？”一种比较"廉价"(即较小成本条件下)的解决思路：第一步：取出含有页面title部分的最小集合。这是“廉价”的关键！第二步：用正则表达式取出和</title</span>
