Abstract

The embodiment of the invention provides a data query method and device. The data query method comprises the steps of receiving a data query request, wherein the data query request comprises information about to-be-queried data; determining a single-page data identifier corresponding to the information about the to-be-queried data according to pre-acquired data page information about a database, wherein the data page information at least comprises every single-page data identifier in the database; requesting data corresponding to the single-page data identifier corresponding to the information about the to-be-queried data from the database; and querying the to-be-queried data corresponding to the information about the to-be-queried data in the requested data. According to the method and the device, the data page information is acquired by utilizing a single-page data identifier in the database, and according to the data page information, the data can be queried by directly acquiring one or more pages of the data corresponding to the information about the to-be-queried data in the database. According to the query method, the data query process is simplified, and the data query efficiency is increased.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data query method and a data query device. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to the data structure. With the development of information technology and market, data management is no longer just storing and managing data, but has transformed into various data management methods required by users. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. With the wide application of large databases, how to quickly query data in the database is particularly important. [0003] In a structured database such as mysql, since the primary key basically increases in order, it is easy to query data based on the primary key. In a semi-structured storag...
