Abstract

The invention discloses an associated data table query method and a device, and relates to the technical field of databases, and the associated data table query method comprises the following steps: establishing a metadatabase according to metadata of each data table; receiving a target data table, and querying an associated data table of the target data table from the metadatabase according to metadata of the target data table; and pushing the associated data table of the target data table to the user, and by establishing the metadatabase and querying the associated data table of the target data table from the metadatabase, so that the automatic query of the associated data table is realized, the query efficiency of the associated data table is improved, and the development of job logic can be more efficient and accurate.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a query method and device for an associated data table. Background technique [0002] When developing job logic in a data system, it is often necessary to associate multiple data tables before forming a job with specific business logic. When performing logic development, the existing technology manually selects multiple associated data tables by developers. Due to the large number of data tables involved, it is a challenge for developers to choose which tables to associate with a table. If the selection is wrong It will affect business results and be inefficient. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] An embodiment of the present invention provides a query method for an associated data table to improve the query efficiency of the associated data table. The method includes: [0005] According to the m...
