Abstract

The invention discloses a data query method and device, electronic equipment and a readable storage medium, and relates to the technical field of big data. According to the specific implementation scheme, the method comprises the steps of: obtaining query request parameters input by a user; analyzing the query request parameters to obtain a plurality of logic tables required by the query and fieldinformation included in each logic table; generating a plurality of inner-layer SQL statements according to the plurality of logic tables and the field information included in each logic table; splicing the plurality of inner-layer SQL statements to obtain a target SQL statement; and performing data query by utilizing the target SQL statement. According to the scheme provided by the invention, the timeliness of data query can be improved, and the requirement of quick business iteration is met.

Description

technical field [0001] This application relates to the field of computer technology, especially to the field of big data technology. Background technique [0002] At present, the B-end of the content ecology stores massive amounts of data such as Baijiahao articles, authors, task systems, and end logs. To extract and obtain the desired data from this massive amount of data, professionals are required to develop sequential combination (MapReduce, MR) tasks or calculation engine spark tasks to query data according to different needs. In this case, due to the long development cycle of MR tasks, etc., the timeliness of data query will be poor, which cannot meet the needs of rapid business iteration. Contents of the invention [0003] The disclosure provides a data query method, device, electronic equipment and readable storage medium. [0004] According to an aspect of the present disclosure, a data query method is provided, including: [0005] Obtain the query request para...
