Abstract

The application provides a database damage recovery method, device and apparatus; the method comprises: accessing a database; judging whether the database is damaged according to access results returned; if yes, using a system master table backed up to cover a current system master table, and continuing to access the database. In database accessing, if it is determined that the database is damaged, the system master table that is backed up can be used to cover the current system master table so as to recover data stored in the system master table, such as table information and index information; after the data stored in the system master table, such as table information and index information, are recovered, most damage of the database can be recovered.

Description

technical field [0001] The present application relates to the technical field of databases, in particular to a recovery method, device and equipment for damaged databases. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to its data structure. When the lock of the database fails, or the database itself has a bug, the data stored in the database may be lost, thereby affecting the use. Contents of the invention [0003] In view of this, the present application provides a damaged database recovery method, device and equipment. [0004] Specifically, this application is achieved through the following technical solutions: [0005] A recovery method for database corruption, comprising: [0006] access the database; [0007] Judging whether the database is damaged according to the returned access result; [0008] When it is determined that the database is damaged, the backed up system master table is used to overwrite ...
