For development or testing purposes, SQL users often need to restore the same database on the same PC or server with a different name. In this tutorial, I am going to explain the detailed steps to restore the same database with different names in SQL Server.

We advise against attaching or restoring databases from unauthorized or untrusted sources for security reasons. These databases may contain malicious code that can alter the physical database structure or schema, run unwanted T-SQL code, or cause problems.

This tutorial will show you various ways to restore the same database with different names in SQL Server.
Method 1 - Using SQL Server Management Studio (SSMS)

Step 1
Open SQL Server Management Studio (SSMS) and connect to the SQL Server Instance.

Step 2
In Object Explorer, right-click Databases and select "Restore Database...".

Step 3
The Restore Database window will appear on the screen. On the General page, use the Source section to specify the source and location of the backup set to be restored. Now, select the Device option and click the Browse (...) button.

Step 3a
Select backup devices window will appear on the screen. Click the Add button to select one or more backup device(s) for the Backup media box.

Step 3b
Locate and select the SQL database backup file(s) (.bak) that you want to restore, and click the OK button to proceed.

Step 3c
After adding the desired backup file to the Backup media list box, click on the OK button to proceed.

Step 4
In the Destination section, the Databases box is automatically populated with the name of the database to be restored. Now, you need to rename the destination database, to do so enter the new name in the Database box. And, leave the default values as it is in the "Restore to" box and "Backup sets to restore" grid.

For example, here I have renamed the Destination Database to "CSHARPCORNER_Backup".

Step 5
Going to the Files page, proceed with the steps to specify the new location or name of the database files (Data and Log files).
    The file names in our case are "CSHARPCORNER_Backup.mdf" and "CSHARPCORNER_Backup_log.ldf," respectively.

Note:

• When you rename the destination database, SSMS itself renames both the data and log files to "Restore As". I remember that in earlier versions of SSMS you had to change manually the names of the files, otherwise, they would conflict with existing files.
• To prevent conflicts, avoid placing new database files in the same directory as the existing database. If necessary, modify the directory name. However, make sure the drive you are using has enough space.

Step 6
Proceeding with the steps again, go to the Options page. Here, you need to make sure that the following options are checked. And, click the OK button.
    "Overwrite the existing database (WITH REPLACE)" under the Restore options section.
    "Take tail-log backup before restore" under the Tail-log backup section. (optional)

Congratulations! the "Database 'CSHARPCORNER_Backup' restored successfully" message shows that our backup database has been successfully restored.

Method 2 - Using Transact-SQL (T-SQL)
With the help of T-SQL, users can also restore the database with a different database name. Follow the below steps to proceed.

Step 1
Optionally, determine the logical and physical names of the files in the backup set that contains the full database backup that you want to restore. This statement returns a list of the database and log files contained in the backup set. The basic syntax is as follows:
RESTORE FILELISTONLY FROM DISK = <Backup_file_location>

Step 2
To restore a full database backup, use the RESTORE DATABASE statement. Use the MOVE option to relocate each of the database files (.mdf & .ldf) and to avoid conflicts with existing files. Because data and log files are restored to their original locations by default. Use the following basic T-SQL syntax to restore the database to a new location and a new name.
RESTORE DATABASE [NEW_DATABASE_NAME]
FROM DISK = N'<BACKUP_FILE_PATH/BACKUP_FILE_NAME.BAK>'
[ WITH
{
    [ **RECOVERY** | NORECOVERY ]
    [ , ] [ FILE = { *backup_set_file_number* | @*backup_set_file_number* } ]
    [ , ] MOVE '*Logical_File_Name_In_Backup*' TO '*Operating_System_File_Name*' [ ,...*n* ]
}

Example
Execute the following T-SQL queries to restore the database with the same name on the same PC or server. Follow the below steps to proceed.

Step 1
Determine the logical and physical names of the files in the backup set by executing the following query.
RESTORE FILELISTONLY FROM DISK = N'F:\FinalDev\Database Backups\CSHARPCORNER\CSHARPCORNER.bak'

Step 2
Once you have obtained the logical and physical names of the database files, execute the below query to restore the same database with a different name.
RESTORE DATABASE [CSHARPCORNER_Backup] FROM DISK = N'F:\FinalDev\Database Backups\CSHARPCORNER\CSHARPCORNER.bak'
WITH FILE = 1,
MOVE N'CSHARPCORNER' TO N'F:\FinalDev\Microsoft SQL Server\DATA\CSHARPCORNER_Backup.mdf',
MOVE N'CSHARPCORNER_log' TO N'F:\FinalDev\Microsoft SQL Server\DATA\CSHARPCORNER_Backup_log.ldf',
NOUNLOAD, REPLACE, STATS = 5
GO

Problems associated with restoring the database

Both methods of restoring the database with the new name are effective and efficient. However, these techniques are not without drawbacks, and you may encounter difficulties such as the following:

    Invalid file format.
    Invalid source file path.
    Incorrect data and log file name.
    Inconsistency errors in the database.
    Insufficient disk space to restore the database.
    Inadequate SQL permissions to run the T-SQL statement.
    To restore an encrypted database, you must have the certificate or asymmetric key that was used to encrypt it. Otherwise, you cannot restore the database without a certificate or asymmetric key.

Note
Apart from these issues, incorrect implementation of a single step to restore a database can corrupt the database and result in potential data loss. Additionally, you may encounter the "SQL database restore failed, database in use" error message.

If you are a database administrator and facing issues while reconnecting log files to MDF files, read this blog. We have shared some easy ways to reconnect the log file to the MDF file.

Methods to Reconnect Log File to MDF File
Here in this blog, I am going to discuss two simple methods to reconnect SQL Log file to MDF database files. The methods are:

    SQL Server Management Studio
    Reconnect Log File without the Transaction File

Let’s explain both methods separately.
SQL Server Management Studio (SSMS) to Reconnect Log File to MDF File
    Login to your computer and search for SQL Server Management Studio.
    Connect to the database either by selecting Windows or Server Authentication.

    Right-click on the Database option and choose Attach. It will lead you to the attached database wizard.
    Now, click on the Add button.
    Here, from the list of database files, select the MDF file you wish to connect with the log file and click on the OK button.
    Click on the message “transaction log file not found” and click OK.
    Finally, reconnect the Log file to the MDF file whether it is connected properly or not.

This is how you can easily reconnect LDF files with the MDF database files.
Reconnect Log File without the Transaction File

Step 1
Specify the DB name and the .MDF file location using the Create Database with Attach option script given below,
USE [master]
Go
CREATE DATABASE [Tester] ON
(FileName = N’C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\Tester.mdf’)
For Attach
GO

Step 2
Once the script is executed, a message will display saying a new transaction log file was created.
Thanks!

Have you forgotten your password for the system administrator (SA) account in SQL Server? Do you want to reset SA password in SQL Server? If you are unable to recall it, Don’t panic! Here in this article, we are providing you with free methods to reset the System Administrator (SA) password in SQL Server.

Use Single User Mode
Make sure the Microsoft SQL Server Management System must be installed on your system before using the Single-User mode. Given steps can be followed,

Enter Windows key+R in the administrator mode.

Type the command net stop MSSQLSERVER and then click the Enter button to stop the SQL instance from running.

Now, restart the SQL Server in the Single-User mode by using this command: net start MSSQLSERVER /m”SQLCMD” and then hit the Enter button.

Here, connect to the SQL Server by entering the command sqlcmd and click on Enter button.

Create user credentials (user name and password) using T-SQL commands. CREATE LOGIN name WITH PASSWORD=’password’. Here, “name” specifies the account name and “password” specifies the new password.

Now, type SP_ADDSRVROLEMEMBER name,‘SYSADMIN’ command to add this recently created user to the System Administrator role using T-SQL command.

Here, you need to exit the SQLCMD command line by typing the command exit and clicking on the Enter button.

Now open Microsoft SQL Server Management Studio using the SQL Server Authentication and login with the recently created user by providing the user name and password and click on Connect button.

Here in the Object Explore section, expand the Security tab>Login and right-click on the SA and click on Properties.

Now in the Login Properties windows, provide the new credentials and click on OK and close it.
This is how you can easily reset SA password in SQL Server effortlessly. I hope this helps!
