Abstract

The embodiment of the invention discloses a data matching method and device as well as a data query method and device. The data matching method comprises the following steps: an application server transmits a query request carrying a query statement and a default value M to a database side; the application server matches to-be-matched data with target data one by one based on the M to-be-matched data returned by the database side, wherein the to-be-matched data is queried by the database side according to the query statement; if the matching of the target data is not completed, the application server matches the to-be-matched data with the target data one by one based on the N to-be-matched data returned by the database side after the return of the M to-be-matched data, wherein N is more than or equal to 1 but less than or equal to M. According to the data matching method and device as well as the data query method and device disclosed by the embodiment of the invention, under the premise of avoiding the memory overflow of the application server, multiple query actions are prevented from causing greater load to the database side.

Description

technical field [0001] This application relates to database technology, in particular to a data matching method, data query method and device. Background technique [0002] At present, there is a need to match data in many scenarios. Generally, the above data matching process is: according to the characteristics of the data a and the characteristics of each data b in the data set Q, the above data a is matched with the data b one by one. In the data matching scenario, the data to be processed can generally be obtained by executing a database query action of a database query statement, such as querying through SQL (Structured Query Language, Structured Query Language). In the prior art, the database query methods applied in the data matching scenario mainly include a full query method and a paging query method. [0003] The full query method generally executes a query action of a SQL statement to obtain a result set containing all the data to be matched that match the query...
