Problems solved by technology

Among them, query condition information, filter condition information, and sorting information are intuitive information, which are easy for users to construct. However, correct and effective grouping and aggregation information can only be constructed under the premise that users fully understand the business logic, which greatly Greatly raised the threshold for using the data query platform, for some users, their data query needs will not be met

Embodiment Construction

[0050] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0051] Please refer to the attached figure 1 , figure 1 It is a schematic flow chart of a data query method disclosed in the present invention, and the method includes the following steps:

[0052] Step S100, acquiring a data query instruction.

[0053]It should be noted that, in this embodiment, the data query instruction is specifically a CommonQuery function constructed by the user. The data query instruction includes query c...

Abstract

The invention discloses a data query method and device, which are used to obtain a data query instruction; analyze the data query instruction to determine query column information; determine the target query scene corresponding to the data query instruction according to the query column information; Querying the correspondence between the scene and the group aggregation mode information, determining the target group aggregation mode information corresponding to the target query scene; performing data query according to the target group aggregation mode information. In the above method and device, since the corresponding relationship between query scenarios and group aggregation information is preset, users do not need to construct group aggregation methods when constructing data query instructions, which lowers the threshold for using the data query platform and meets the data query needs of ordinary users.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data query method and device. Background technique [0002] All software information systems are inseparable from data query. Data query is the core operation of the database, and data query refers to extracting the required data from the database according to the needs of users. [0003] Currently commonly used data query methods require users to construct data query instructions, and then pass the constructed data query instructions to the API (Application Programming Interface, Application Programming Interface) of the data query platform to obtain data query results. In addition to query condition information, filter condition information, and sorting information, the data query instruction constructed by the user must also include grouping and aggregation mode information. Among them, query condition information, filter condition information, and sorting inform...
