Abstract

The embodiment of the invention discloses an information query method. The method comprises the steps of obtaining a to-be-analyzed programming statement; wherein the to-be-analyzed programming statement is generated by adopting a target programming language; analyzing the to-be-analyzed programming statement to determine a first syntax structure tree; wherein each node in the first grammar structure tree represents a grammar structure in the grammar structure tree; determining a basic data structure based on a programming statement corresponding to the target programming language; based on the basic data structure, reconstructing the first grammar structure tree to obtain a second grammar structure tree; wherein the second grammar structure tree comprises a data structure in the first grammar structure tree; and receiving a statement query request, and performing statement query from the second syntax tree based on the query request. The embodiment of the invention further discloses an information query device and equipment and a computer readable storage medium.

Description

technical field [0001] The present application relates to information query technology in the field of information query, and in particular, to an information query method, apparatus, device, and computer-readable storage medium. Background technique [0002] With the continuous popularization of electronic devices, various functions can be implemented on electronic devices through computer programming statements; in practical applications, we often need to parse computer programming statements (such as sql statements), and traverse and extract table connection patterns from them. , statistical dimension information and other logical operations; however, when encountering multi-level nesting and multiple aliases, the existing parsing framework cannot be accurately identified, and manual secondary extraction is still required, so that information cannot be extracted without manual extraction. Extraction problem. SUMMARY OF THE INVENTION [0003] In order to solve the above...
