Abstract

The invention discloses a relational database query method, device and equipment and a storage medium. The method comprises the steps that when it is detected that connection between a current projectand a database is successful, a database management system function is called to obtain an original data result set of the database; Reading metadata of the database from an original data result set,and generating a metadata model based on the metadata and through the database management system function; Creating and constructing a query function based on the metadata model; the structure of thedatabase is changed; a programmer does not need to modify a source code related to the database query statement in the current project; and the database can be queried by directly calling the construction query function, so that the workload of a programmer in development and testing is effectively reduced, meanwhile, the service requirement can be quickly responded, and the experience degree ofa user on project software is improved.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to a relational database query method, device, equipment and storage medium. Background technique [0002] A relational database is a database based on a relational model, which uses mathematical concepts and methods such as set algebra to process data in the database. Various entities in the real world and various links between entities are represented by relational models. The standard data query language SQL (Structured Query Language) is a language based on relational databases, which executes the retrieval and operation of data in relational databases. The relational model consists of three parts: relational data structure, relational operation set, and relational integrity constraints. A relational database is a database composed of multiple two-dimensional row-column tables that can be connected to each other. Therefore, every time a relational database is es...
