How to restore a database from backup using SQL Server Management Studio 2019
If you have SQL Server Management Studio installed, you can restore database backup using its interface alone. Just follow the instructions:
1. Connect to your SQL Server and right-click on the “Databases” directory and choose “Restore Database”
for more info follow the below link
https://sqlbackupandftp.com/blog/restore-database-backup
Done
The above solutions missed out on where to keep your backup (.bak) file. This should do the trick. It worked for me.
You can use node package, if you often need to restore databases in development process.
Install:
npm install -g sql-bak-restore
Usage:
sql-bak-restore <bakPath> <dbName> <oldDbName> <owner>
Arguments:
!! sqlcmd command line utility should be in your PATH variable.
Simply use
sp_restoredb 'Your Database Name' ,'Location From you want to restore'
Example: sp_restoredb 'omDB','D:\abc.bak'
After opening and logging in to MS SQL Server Management studio
...
You're done!
Instead of choosing Restore Database..., select Restore Files and Filegroups...
Then enter a database name, select your .bak file path as the source, check the restore checkbox, and click Ok. If the .bak file is valid, it will work.
(The SQL Server restore option names are not intuitive for what should a very simple task.)
You can simply restore these database backup files using native SQL Server methods, or you can use ApexSQL Restore tool to quickly virtually attach the files and access them as fully restored databases.

.bak files are database backups. You can restore the backup with the method below:
How to: Restore a Database Backup (SQL Server Management Studio)
This will show you a list of database files contained in DB.bak:
RESTORE FILELISTONLY
FROM DISK = 'D:\3.0 Databases\DB.bak'
You will need the logical names from that list for the MOVE
operation in the second step:
RESTORE DATABASE YourDB
FROM DISK = 'D:\3.0 Databases\DB.bak'
and you have to move appropriate mdf,ndf & ldf files using
With Move 'primarydatafilename' To 'D:\DB\data.mdf',
Move 'secondarydatafile' To 'D:\DB\data1.ndf',
Move 'logfilename' To 'D:\DB\log.ldf'
On SQL Server Management Studio
Done.
Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example
RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO
In above Query you need to keep in mind about .mdf/.ldf file location. You might get error
System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)
So you need to run Query as below
RESTORE FILELISTONLY
FROM DISK = 'D:\AdventureWorks2012.BAK'
Once you will run above Query you will get location of mdf/ldf use it Restore database using query
USE MASTER
GO
RESTORE DATABASE DBASE
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF',
NOUNLOAD, REPLACE, NOUNLOAD, STATS = 5
GO
