Abstract

The invention provides a multi-source database statement checking method and device, which can be applied to the technical field of big data, and the method comprises the following steps: performing grammatical analysis on to-be-analyzed structured query statements respectively corresponding to a plurality of databases to obtain an abstract syntax tree; determining preset rules according to the databases corresponding to the to-be-analyzed structured query statements; and performing rule analysis on the structured query statements of the abstract syntax tree node through the preset rules to obtain a statement check result. The invention can realize check of the structured query statement of the multi-source databases so as to improve accuracy and the execution efficiency of the structuredquery statements.

Description

technical field [0001] The present invention relates to the technical field of databases, in particular to the technical field of big data, in particular to a multi-source database statement checking method and device. Background technique [0002] With the continuous development of Internet technology, the storage of data information is not limited to a single stand-alone relational database. More and more enterprises begin to use distributed database and big data technology to deal with massive data scenarios. By writing SQL (structured query language) to operate on data in the database. For business personnel, data analysts, etc., facing a variety of heterogeneous data sources, if they are not familiar with the characteristics of each data source, it is easy to write SQL scripts with low execution efficiency. In a production environment, SQL scripts with low execution efficiency will occupy more computer resources, which in turn will affect the normal development of othe...
