Whereas, the users not having in depth knowledge can opt for the automated solutions. Let’s understand what each method provide to users.
T-SQL Command Method – There are different commands for all the three cases & this is why this method becomes a bit challenging for all the users.

How to Restore Specific Tables from SQL Backup Step by Step in Database?
Case:1 Restoring Rows Deleted from an Existing Table
Here, what users need to do is very simple. We’ll create a new database & then copy the backup data to that DB. Then we’ll copy the required files from this newly created DB to our main database.
After creating a new database, users need to integrate the SELECT & INSERT command for executing this task as mentioned in the below commands.
USE My_Database
GO
SET IDENTITY_INSERT my_table ON
INSERT INTO my_table_1 (column_name)
Now, enter the below query:
SELECT * FROM My_Database_Restored.my_table
SET IDENTITY_INSERT my_table OFF
Case:2 Restoring Specific Tables from Completely Drooped SQL Database Tables.
Now, we have some different commands for users that want to restore completely deleted tables back. For this, they need to execute the SELECT INTO CMD as shown below.
USE My_DatabaseGOSELECT * INTO my_table
FROM My_Database_Restored.my_table
Case:3 Fixing the Damaged Rows Using Backup for Selected SQL Tables
To update the damaged or corrupt data, users can take help from the MERGE command.
USE My_Database
GO
SET IDENTITY_INSERT my_table ON
MERGE my_table dest
USING (SELECT * FROM My_Database_Restored. my_table src) AS src
ON dest.(column_name_1)= src.(column_name_1)
WHEN MATCHED THEN UPDATE
SET dest. (column_name_2) = src. (column_name_2), dest. (column_name_3) =
src. (column_name_3)
WHEN NOT MATCHED THEN INSERT
(column_name_1,column_name_2,column_name_3) VALUES
(src. (column_name_1), src. (column_name_2), src. (column_name_3));
SET IDENTITY_INSERT my_table OFF
