How can a deleted table be restored in SAP HANA?

To restore a deleted table in SAP HANA, the backup and recovery feature is the appropriate and reliable method. This feature allows for the restoration of not just individual tables, but entire databases or specific schemas, depending on the requirements of the situation. When a table is deleted, it is not just removed instantly; rather, this action is logged in the database's transaction logs. Therefore, using the backup and recovery tools in HANA, you can revert to a previous state of the database where that table existed, effectively restoring it.

The other options do not provide viable means of recovery for a deleted table. Manually creating a new table, while possible, would not restore the original structure, data, or any associated indexes or constraints that were part of the deleted table. Querying the table history primarily offers insights into changes and transactions related to the table rather than directly restoring it. Lastly, copying data from another database would not be feasible unless you had an identical setup that contained the original table, and it would not guarantee the restoration of the precise state or configurations of the deleted table in the context of the original database environment. Thus, leveraging the backup and recovery feature is the best practice for restoring a deleted table in SAP HANA.
