基于Delphi的通用多条件查询模块的设计与实现

The Design & Implementation of a Generic, Multi-conditional Querying Routine Based on Delphi

目前数据库的使用已十分普及,但对数据库中数据的查询缺乏统一有效的实现方法。文章介绍在Delphi中通过过滤数据集(DataSet)实现通用多条件查询的一种有效方法,使Delphi应用程序有一种统一有效的查询方法,从而加快应用程序的开发速度。

Databases are nowadays widely used, but we are still lacking unified effective methodology in querying databases. This article introduces an effective method for implementing generic, multi-conditional queries by using dataset filtration as well as an effective query method in Delphi applications so as to speed up application development.
