“指针”在RDBS查询语言中的创新应用

The Application of Point in RDBS

在RDBS中,利用SQL语句进行表的相关查询时,通常都是利用相关名的说法来解释。该文引入了“指针”这一其他语言中常用的结构,从另一个角度对相关查询的算法产生和实现做出了更为合理的解释,并且实践效果较好。

In the RDBS,catalogs name is usually referred when the catalogs query is acting in the table by the means of SQL.But this thesis points out a much more practical structure“point ”,which can help people easily understand and settle the probable puzzling.And after a long time of research,the point can be acceptable by most people.
