Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] During the execution of the business in the server, business data will be generated and saved in the business data table, and the business data in the business data table will eventually be saved in the full data table.

[0051] The existing technology adopts the insert update method, that is, according to the primary key and update time of the business data table, insert (insert) the business data added in the incremental data table into the full data table, and update the modified business data in the incremental data table (updated) to the full data sheet. Wherein, the primary key (primary key) is one or more fields in the data table, and its value is used to uniquely identify a certain record ...

Abstract

The invention provides a method and a system for updating a database, which solve the problem that the resource consumption is large in a database updating process. The method comprises the following steps of establishing a finished table and an unfinished table in a full data table, wherein the finished table stores service-finished service data, and the unfinished table stores service-operating service data; receiving incremental data sent by an incremental data table, wherein the incremental data comprises service data in a finished state and / or service data in an unfinished state; respectively querying the state of each incremental data; if the state of each incremental data is finished, identifying that the incremental data is the service-finished service data, and adding a record of the increment data at the tail of the finished table in the full data table; if the state of each incremental data is unfinished, identifying that the increment data is the service-operating service data, and adding a record of the increment data in the unfinished table in the full data table.

Description

technical field [0001] The present application relates to data processing technology, in particular to a method and system for updating a database. Background technique [0002] During the process of data synchronization in the database, that is, during the update process of the data table, it is necessary to periodically synchronize the data in the business data table to the incremental data table, and then merge the data in the incremental data table into the full data table . [0003] Among them, the method of merging the data in the incremental data table into the full data table is the insert update method, that is, according to the primary key and update time of the business data table, insert (insert) the added data in the incremental data table into the full data In the table, update (update) the modified data in the incremental data table to the full data table. [0004] However, when using the insert update method, it is necessary to traverse all the data in the ...
