SQL Server: Importing database from .mdf?

I have SQL Server 2008 Express and SQL Management Studio 2008 Express installed on my local box.

How in the world do I import this .mdf file as a new database into my SQL Server?

This seems like a ridiculously common task that must be performed thousands of times a day across the globe, and I cannot figure out how to do it in Management Studio Express.

What am I missing?

Open SQL Management Studio Express and log in to the server to which you want to attach the database. In the ‘Object Explorer’ window, right-click on the ‘Databases’ folder and select ‘Attach. ‘ The ‘Attach Databases’ window will open; inside that window click ‘Add. ‘ and then navigate to your .MDF file and click ‘OK’. Click ‘OK’ once more to finish attaching the database and you are done. The database should be available for use. best regards 🙂

Different methods to attach SQL Server MDF files

This article demonstrates different methods to attach SQL Server MDF files. First, let me explain about the database files.

A SQL Server database has three types of files:

Primary Data File OR MDF File
Secondary data file OR NDF File
Log File OR LOG File

Primary data file OR MDF file

The SQL Server database stores data in MDF files. Typically, .mdf is a preferred extension of the primary database file. It is not a type of file. You can use another extension (*.gbn) to create a primary database file without any error. The primary data file contains columns, fields, rows, indexes, tables, and data added by an application. It also contains the vital information of the database.

Secondary data file OR NDF file

The secondary datafiles are optional. The purpose of the primary data file and secondary data file (.ndf file) are the same. Secondary data files are useful when we want to stripe the data across multiple drives of the database server. For example, if you want to keep the tables on X drive and indexes on Y drive, then you can keep the tables on the primary data file and indexes on the secondary data file.

Log file OR LDF file

It stores the changes made in the database by insert, update, delete, etc. LDF file has all the information that can be used to recover a database.

How to find the location of the MDF files

We can obtain the location of the database files by querying sys.database_files and sys.master_files dynamic management views. The difference is between sys.master_files provides the physical location of all the databases and sys.database_files provides the information of the specific database.

For the demonstration, I have restored the “WideWorldImportors” demo database. You can download it from here. Now to obtain the location of database files from sys.master_files DMV, execute the following query.

Following is the screenshot of the output:

Obtain database file name using sys.master_files

To obtain the information of the database files from sys.database_files DMV, execute following query:

Obtain database file name using sys.database_files

To view the database files location using SQL Server management studio, open SSMS Connect the database engine Expand databases right-click on “WideWorldImportors” Select properties. See the following image:

Open database properties

In properties, select files. In “Path” and “File Name” columns show the location of the database files. See the following image:

Database properties

We can attach the SQL Server database files using the following methods:

Using the SQL Server Management Studio
Using T-SQL Script

Attach MDF File using SSMS

To attach a database using SSMS, first, open SSMS connect to the database engine Right-click on “databases” select “Attach.” See the following image:

Attach database

On the Attach Database dialog box, click on Add (Screen 1). On locate database dialog box (Screen 2), locate the database MDF files which you want to use to create the database. By default, the “locate database files” dialog box uses the default database file location, but you can navigate to the other location of the database file or provide the location in the “database data file location” textbox. Select the desired database file and click OK. See the following image:

Locate database mdf file

On attach database file dialog box, you can review the database details in “Database to attach” and database file details in the “AdventureWorks2017 database details” box. See the following image:

Attach database screen for the mdf file

Click on OK to attach the database. Once the database attaches successfully, you can view the database in object explorer. See the following image:

new database has been attached

Attach MDF File using T-SQL Query

We can also attach the database using “CREATE DATABASE.. WITH ATTACH” or “exec sp_attach_db” T-SQL commands. The syntax of “CREATE DATABASE.. WITH ATTACH” command is as follows:
