Abstract

The invention provides a multi-condition paging query optimization method and system, a terminal and a storage medium. The multi-condition paging query optimization method comprises the steps of acquiring related tables according to query conditions, and counting the number of related data of the related tables; acquiring the sequence of each correlation table and the data quantity of each page atthe front end; calculating the number of target data according to the number of target query pages at the front end and the number of data of each page; and determining the correlation table to whichthe target query page number belongs according to the target data number, the data number of each page, the correlation data number of each correlation table and the sequence. Full-table scanning isavoided, a temporary table does not need to be generated in an associated mode, and the data query efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data query, in particular to a multi-condition paging query optimization method, system, terminal and storage medium. Background technique [0002] With the development of time and the maturity of software, in the current physical infrastructure management, the amount of data is also increasing. The software will involve a large number of queries, among which multi-condition multi-table paging query is the most important display method of software management data. However, the common query method will waste a lot of time when querying multiple tables, making the query slow. The associated query keywords used include: LEFT JOIN; RIGHT JOIN; INNER JOIN; UNION. [0003] MYSQL's multi-table associated paging query is the following steps: scan the qualified data in each sub-table. Combine the matched data in the previous step to form a temporary virtual table through association. Return specific da...
