This article provides information on how to restore a table from a backup in Oracle.
To restore a table from a backup in Oracle, you must first open the backup file. You can do this with the following command:
OPEN filename [READ ONLY]
If the file is in a format that Oracle can understand, it will be opened. If the file is not in a format that Oracle can understand, you will receive an error.
Once the file is open, you can restore the table using the following command:
REPLACE TABLE table_name
If the table does not exist, it will be created. If the table exists, it will be replaced with the contents of the backup file.
If you want to restore only a portion of the table, you can use the following command:
REPLACE TABLE table_name PARTITION (partition_name)
If the table does not have a partition named “partition_name”, the table will be replaced with the contents of the backup file.

Can I restore a table from RMAN backup?
Can you restore a table from an RMAN backup?
Yes, you can. In fact, you can restore any object from an RMAN backup. However, there are a few things you need to know before you start.
First, you need to know the name of the table you want to restore. Second, you need to know the RMAN backup file that contains the table. Third, you need to know the RMAN restore command that will restore the table.
Once you have all of this information, you can start the restore process. First, use the RMAN LIST command to find the RMAN backup file that contains the table you want to restore.
Next, use the RMAN RESTORE command to restore the table. The command syntax is as follows:
RESTORE TABLESPACE
In this command, is the name of the RMAN backup file that contains the table you want to restore, and is the name of the tablespace that contains the table you want to restore.
Finally, execute the command and wait for the restore process to finish. When it is finished, the table will be restored and ready to use.
How do I restore a dropped table in Oracle using RMAN?
If you accidentally drop a table in Oracle, you can use RMAN to restore it. RMAN is the Oracle Recovery Manager, and it can be used to restore both datafiles and tablespaces.
To restore a table using RMAN, you first need to connect to the database using the RMAN utility. Then, you need to use the restore table command to restore the table. The syntax for the restore table command is:
restore table [] []
The parameter is the name of the table you want to restore. The parameter is the name of the datafile that contains the table. The parameter is the name of the tablespace that contains the table.
If you don’t specify a datafile name, RMAN will restore the table to the default datafile. If you don’t specify a tablespace name, RMAN will restore the table to the default tablespace.
Here’s an example:
restore table my_table
This command will restore the table my_table from the default datafile.
If you want to restore the table to a different datafile, you can use the following syntax:
restore table []
The parameter is the name of the datafile that you want to restore the table to.
Here’s an example:
restore table my_table to ‘C:\tables\my_table.dbf’
This command will restore the table my_table to the C:\tables\my_table.dbf datafile.
If you want to restore the table to a different tablespace, you can use the following syntax:
restore table []
The parameter is the name of the tablespace that you want to restore the table to.
Here’s an example:
restore table my_table to ‘new_tablespace’
This command will restore the table my_table to the new_tablespace tablespace.
How can I recover a table in Oracle?
Oracle is a powerful relational database management system (RDBMS) that can be used for a variety of purposes, from developing applications to storing and managing data. In some cases, you may need to restore a table that has been lost or damaged. This can be done using Oracle’s built-in backup and restore features.
There are a few different ways to restore a table in Oracle. The first is to use the Oracle Data Pump utility. The Data Pump utility can be used to export and import data between databases. It can also be used to restore data from a backup file.
Another way to restore a table is to use the Oracle Recovery Manager (RMAN) utility. The RMAN utility can be used to create and manage backups, as well as to restore data from a backup.
Finally, you can use the SQL*Loader utility to restore a table. The SQL*Loader utility can be used to import data into an Oracle database.
Each of these methods has its own advantages and disadvantages. The best method for restoring a table will vary depending on the specific situation.
How can I recover a table in 12c?
Oracle Database 12c introduced a new feature called In-Place Table Redefinition. This feature allows you to redefine a table without having to export and import the data. The In-Place Table Redefinition feature can be used to change the structure of a table, including adding or dropping columns, changing the datatype of a column, and changing the default value of a column.
The In-Place Table Redefinition feature can be used to recover a table that has been damaged or deleted. To recover a table, you first need to create a new table that is the same as the original table. You then use the In-Place Table Redefinition feature to copy the data from the original table to the new table.
How do I recover a dropped table in Oracle without flashback?
In Oracle, a table is dropped when its definition is removed from the database. If the table is dropped accidentally, you may need to recover it. You can recover a dropped table without flashback by using the Oracle Data Pump import utility.
How do I restore a table from the recycle bin?
There may come a time when you need to restore a table from the recycle bin. Perhaps you accidentally deleted the table, or maybe it was accidentally deleted by someone else. No matter the reason, it’s important to know how to restore a table from the recycle bin.
To restore a table from the recycle bin, open SQL Server Management Studio and connect to your database. Expand the Tables node, right-click the table you want to restore, and select Restore Table.
In the Restore Table window, select the database and table where you want to restore the table, and click OK. SQL Server will restore the table from the recycle bin and display a message indicating that the table was successfully restored.
How do I restore a dropped table?
