However, in this process, after the modified SQL script is verified, the structure of the database has changed. If the SQL script fails to be verified, it cannot be returned to its initial state before the verification, and the above steps are re-executed. Heavy workload and low work efficiency

Abstract

The invention discloses a database data structure verification method and apparatus. The method comprises: obtaining associated information between different data tables in an original database; obtaining influence information of each data table in the original database on other tables in the original database when the in-table field changes according to the associated information among differentdata tables in the original database; creating a temporary database, and obtaining a preset environment standard in combination with the influence information; according to a preset environment standard, establishing a temporary data table corresponding to the data table in the original database in the temporary database; and verifying the updated data structure in the original database accordingto the temporary data table, and emptying the temporary database if the verification fails. According to the method, all data and structures in the original data table do not need to be correspondingto the temporary data table, so that the efficiency of subsequently using the temporary data table for verification is improved. And if the verification fails, only the temporary database needs to beemptied, and the temporary data table is re-established for verification, so that the workload is relatively small.

Description

Technical field [0001] The present invention relates to the technical field of databases, in particular to a method and device for verifying the data structure of a database. Background technique [0002] In project and product development, the data structure between multiple versions of relational databases often changes. At present, the industry generally implements operations such as adding or deleting fields to data tables in the database, adding indexes, and cutting over data in tables by changing Structured Query Language (SQL) scripts. [0003] In the specific operation, generally the designer or developer first submits an application for data structure or data changes, and then the reviewer will review, modify the SQL script, and verify the modified SQL script. After the verification is passed, it will be persisted. Save the SQL script and deliver the product or project for use. However, in this process, after verifying the modified SQL script, the structure of the databa...
