Embodiment Construction

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] Before introducing the data query method provided by the embodiment of this application, some concepts involved in the embodiment of this application are introduced first:

[0028] JavaScript Object Notation (JSON) is a lightweight data exchange format; JSON is based on a subset of ECMAScript (the js specification developed by the European Computer Association), and JSON is stored in a text format completely independent of the programming language and represent data. The concise and clear hierarchical structure makes JSON an ideal data exchange language; JSON is easy for humans to read and write, but also easy for machines to parse and generate, and effectively improves the efficiency of network transmission.

Abstract

The invention provides a data query method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining a key value pair set which is a set comprising identification keys and specific values corresponding to the identification keys; parsing the key value pair set according to a preset rule to obtain a structure query language statement and a database parameter set; and executing the structure query language statement in a database according to the database parameter set to obtain a data query result. In the implementation process, the predefined query preset rule between a supplier of a query result and a demander of the query result is achieved; and when the demander of the query result puts forward a new demand, and if the demander of the query result complies with the preset rule, the query result still can be normally obtained, so that the supplier does not change the previously realized preset rule any more, the query conditions can berandomly combined, and the query service interface is not modified any more, thereby improving the stability of the server side in the production environment.

Description

technical field [0001] The present application relates to the technical fields of data processing and databases, and in particular, to a data query method, device, electronic equipment, and storage medium. Background technique [0002] Database (DataBase, DB) refers to a collection of stored electronic data or electronic files. In short, it can be regarded as an electronic filing cabinet. Users can perform operations such as adding, intercepting, updating, and deleting data in files; The database here is a data collection that is stored together in a certain way, can be shared with multiple users, has as little redundancy as possible, and is independent of the application program. [0003] The current way to obtain query data is for example: the client calls the data query service interface of the server according to the query conditions, and obtains the data query results sent by the server; the client here can be a terminal device, and the server here can be a business ser...
