Title:
TABLE DATA QUERY METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040722
Kind Code:
A1
Abstract:
Disclosed are a table data query method and device, wherein same fall within the technical field of information. The method comprises: parsing a table data query request sent by an application program; receiving a parameter value of a query parameter sent by the application program; according to query partition key values of a plurality of data tables, determining query partitions of the plurality of data tables; when the query partitions of the plurality of data tables are the same, sending the table data query request to a target database; and sending a final query result returned by the target database to the application program. In the present invention, after it is determined that the query partitions of a plurality of data tables are the same according to query partition key values of the plurality of data tables, a received table data query request is sent to a database corresponding to the query partitions, and a final query result returned by the database is then sent to an application program. During this process, the plurality of data tables do not need to be processed twice, thus not only improving the query efficiency of table data, but also reducing the amount of data transmitted, thereby improving the service performance.
