Abstract

The invention provides a method and device for controlling a single piece of data to be output. The method includes the steps that a vernier parameter M configured by a database is obtained, wherein the vernier parameter M represents the number of data which the database allows to output at the same time; the natural number N smaller than M is generated according to the vernier parameter M; the request of locking the N piece of data is sent to the database; the N piece of data locking result information returned by the database is received; under the condition that the locking result information indicates success, the request of modifying the state of the N piece of data into the used state is sent to the database to complete the output operation on the N piece of data. By applying the embodiment, the efficiency of outputting the single piece of data can be improved, and concurrence output operation on the same data can be reduced.

Description

technical field [0001] The present application relates to the technical field of databases, in particular to a method and device for controlling a single piece of data out of a database. Background technique [0002] Generally, when the data requester wants to operate the data in the database, it needs to send an operation request to the database. For example, if a requester wants to obtain a piece of data, it needs to send an operation request for this data to the database, and the database receives the operation request After finding the data, the outbound operation of the data will be completed. [0003] In some scenarios where a single piece of data is out of the database, that is, each requester can only out one piece of data, it is easy to happen and issue the database. For example, if there are 100 requesters fetching 100 pieces of data at the same time, and each requester can only get 1 piece of data, it is easy to send out the database, that is, multiple requesters...
