8. Rebuild indexes and constraints: During the database repair process, it may be necessary to rebuild indexes and constraints. This can be done by executing SQL statements to ensure the integrity and consistency of the database.
9. Test the repaired database: After completing the database repair, testing is required to ensure data integrity and normal functionality. You can perform some query, update, and delete operations to verify the repair effect.
10. Monitoring and recording: After completing the database repair, the performance and stability of the database need to be continuously monitored. At the same time, record the repair process and results for future reference and improvement.
