How to solve the failure of recovering deleted data in PL/SQL.
If the recovery of deleted data in PL/SQL fails, you can try the following solutions:
- Check for backups: The first step is to check if there are any backups available to restore the deleted data. If there are backups, you can try to recover the data from them.
- Flashback queries can be used to recover deleted data in a database table that has flashback functionality enabled. For instance, you can use SELECT … AS OF TIMESTAMP or SELECT … AS OF SCN to query historical data.
- Utilize recovery tools: You can try using specialized database recovery tools to recover deleted data. These tools can typically restore data from the database’s log files or other sources.
- Consult with a professional: if the above methods are unable to solve the problem, seek advice from a database administrator or a database recovery expert to help you resolve the issue.
In general, restoring deleted data requires careful handling to avoid further damage to the database. It is best to backup the database before proceeding with any operation to prevent any unforeseen accidents.
