摘要
介绍了PostgreSQL的整体架构,着重针对其解析器模块进行底层研究,分析查询请求在解析器模块中的查询处理过程和其内部各种函数的调用关系,最后就其解析器模块的开源代码做出的剖析以全面理解该模块的运作,并通过一个子查询程序调试实现了一个基本的查询请求。
The paper introduced the integrated framework of PostgreSQL firstly. Then, put an emphasis on its parser, and analysed the query processing procedure of the query requests in parser and the calling relationship of various functions internally. Finally, dissected the open-source code of parser in order to understand the movement in parser in a round. Last but not least, we realized an essential query request by debugging a subquery programme.
