Abstract

The invention discloses a data query method, query service equipment, client equipment and a data system. The method includes: receiving a first query request sent by a client device, the first query request includes query conditions and page prompt information, the page prompt information is used to indicate the first data record in the first page, and the first page is A data page in at least one data page that satisfies the query condition; according to the page prompt information, determine the first data record; according to the first data record and the query condition, send the first data page to the client device data record. The data query method, query service device, client device and data system of the embodiments of the present invention can improve the efficiency of paged query.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, to a data query method, query service equipment, client equipment and a data system. Background technique [0002] Pagination query technology can support users to view data records of a certain page. In the current paging query technology, one way is to cache all the records that meet the query conditions in the memory first, and when the user submits a query request for a certain page, the data that the user wants is directly obtained from the memory quickly. returned to the user. This method puts a lot of pressure on the memory when the amount of data involved in the query is too large, or the amount of concurrent requests is too large, especially in the field of big data. [0003] Another way is to organize and sort the data directly according to the row number (ROW_NUM), and quickly locate the data you want to query according to ROW_NUM when querying. H...
