The sample database AdventureWorks plays an important role while performing test operations and learning about new features. So after the installation of SQL Server 2012 and searching for the sample database AdventureWorks I found that it contains only the "mdf" file to download. This tip gives you the steps you need to follow to install the sample database with only the data (mdf) file.
I tried to attach the database using SQL Server Management Studio as follows:
Right Click on Databases > Attach and click Add... > select the AdventureWorks mdf file.
Notice the message above in front of log file "Not Found". However if I click on OK to proceed with the attach database I get the following error.
By using SQL Server Management Studio we cannot simply attach the sample database "AdventureWorks" without the log file. What we need to do is to delete the log file from the attach database.
To do this, select the log file which is showing as "Not Found" as seen below.
Select the log file and remove the log file by clicking on the Remove button. The attach now only contains the MDF as shown below. Click OK to attach the database and this should work.
Using T-SQL to Attach the Database
To attach a database without the log file we need to use the Attach_Rebuild_Log option.
The ATTACH_REBUILD_LOG specifies that the database is created by attaching an existing set of operating system files. If one or more transaction log files are missing, the log file is rebuilt using this command. The ATTACH_REBUILD_LOG automatically creates a new, 1-MB log file and this file is placed in the default log file location.
So the command would be:
CREATE DATABASE AdventureWorks2012_Data
ON (FILENAME = N'E:\SQLData\AdventureWorks2012_Data.mdf')
As the screenshot above shows SQL Server created a new log file for the database.
In order to use the ATTACH_REBUILD_LOG this requires the following:
A clean shutdown of the database
All data files (MDF and NDF) must be available
Verify Logical and Physical Integrity of Database
Once we have the database attached, we can check the logical and physical integrity of all the objects within the database by executing a DBCC CHECKDB.
DBCC CHECKDB ('AdventureWorks2012_Data')
Download the AdvertureWorks database and use it to test some of the new features in SQL Server 2012
CREATE FILE encountered operating system error 5(Access is denied.) while attempting to open or create the physical file 'C:\Program Files\Microsoft SQL Server\AdventureWorks2012_Data_log.ldf'. Could not open new database 'AdventureWorks2012'. CREATE DATABASE is aborted. File activation failure. The physical file name "C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\AdventureWorks2012_Log.ldf" may be incorrect. (Microsoft SQL Server, Error: 5123)
I received the error above and cannot get the database to attach. I am logged in as an administrator and have ensured I has rights to everything. I am trying to teach myself SQL Server 2012 but can't even get past this first step. Any help would be much appreciated. Thank you!
