This section describes how to attach a database in SQL Server by using SQL Server Management Studio. Only one database can be attached at a time.
Attaching a database requires any of the following permissions: CREATE DATABASE, CREATE ANY DATABASE, or ALTER ANY DATABASE. Normally, these permissions are granted to the sysadmin role of the instance.
To attach a database
Run Microsoft SQL Server Management Studio.
Connect to the required SQL Server instance, and then expand the instance.
Right click Databases and click Attach.
Click Add.
In the Locate Database Files dialog box, find and select the .mdf file of the database.
In the Database Details section, make sure that the rest of database files (.ndf and .ldf files) are found.
Details. SQL Server database files may not be found automatically, if:
They are not in the default location, or they are not in the same folder as the primary database file (.mdf).Solution: Specify the path to the required files manually in the Current File Path column.
You have recovered an incomplete set of files that make up the database. Solution: Recover the missing SQL Server database files from the backup.
