Embodiment Construction

[0030]The present invention will be specifically introduced below in conjunction with specific embodiments.

[0031]The data query method based on the infinite classification of left and right values ​​provided by the embodiments of the present invention includes the following steps:

[0032]S101: Receive a data query request carrying a minimum lower limit value and a maximum upper limit value;

[0033]S102: Obtain data that meets the requirements according to the preset left and right values ​​of each piece of data in the database to obtain a data set;

[0034]S103: Send the data set to the client.

[0035]Optionally, before obtaining the data that meets the requirements according to the preset left and right values ​​of each piece of data in the database, the method further includes:

[0036]Use the left and right value infinite classification to realize the algorithm, and set the left value and right value for each piece of data in the database.

[0037]Optionally, after sending the data set to the c...

Abstract

The invention discloses a data query method based on a left-right value infinite classification implementation algorithm, which relates to the technical field of data processing, and comprises the following steps of: receiving a data query request carrying a minimum lower limit value and a maximum upper limit value, and obtaining data meeting requirements according to preset left and right valuesof each piece of data in a database to obtain a data set; and sending the data set to a client, so that efficiency is improved, the server load is reduced, and user experience is improved.

Description

Technical field[0001]The invention relates to the technical field of data processing, in particular to a data query method based on an infinite classification of left and right values ​​to realize an algorithm.Background technique[0002]At present, the query of multi-level data is mainly carried out by way of traversal. For tree-shaped data with a more complex hierarchical structure, the recursion time is longer, it takes up more service resources, and requires frequent interaction with the database, resulting in low efficiency.Summary of the invention[0003]In order to solve the shortcomings of the prior art, the embodiment of the present invention provides a data query method based on the infinite classification of left and right values ​​to realize an algorithm, the method includes the following steps:[0004]Receive data query requests carrying the minimum lower limit value and the maximum upper limit value;[0005]According to the preset left and right values ​​of each piece of data ...
