Creating the Wide World Importers sample database v1.0

Before SQL Server 2005, we had the northwind and pubs sample database, these actually shipped with the product. If you did a SQL Server 2000 install, you would see these two database in addition to the system databases.

With SQL Server 2005 this changed, there were no more sample databases included. Instead new databases were made available for download, for a while now we have the AdventureWorks available. Today I wanted to see if there was a AdventureWorks 2016 database available. I couldn't find it. Instead I found the Wide World Importers sample database v1.0.

These sample databases live now on github

Here is the link https://github.com/Microsoft/sql-server-samples

As a normal person you will probably navigate to the databases folder https://github.com/Microsoft/sql-server-samples/tree/master/samples/databases and in there you will probably go to https://github.com/Microsoft/sql-server-samples/tree/master/samples/databases/wide-world-importers/wwi-database-scripts

Then you will see the following scripts

Now if your name is Denis or you like to waste time (or both), you think..cool I will download this repo and run these files. That is not unreasonable to think...... but

To save you some time, here is the easiest way to put this database on your SQL Server instance

Instead of running those scripts, go to this page https://github.com/Microsoft/sql-server-samples/releases/tag/wide-world-importers-v1.0 scroll down to downloads, download the 121 MB file named WideWorldImporters-Full.bak

While that is downloading, create a folder on you C drive named SQL, in that folder create 2 folders one named Data and one named Log, it should look like in the image below

Now assuming the backup file is on the C drive, here is what the restore command should look like

USE [master]
RESTORE DATABASE [WideWorldImporters] 
FROM DISK = N'C:\WideWorldImporters-Full.bak' WITH FILE = 1, 
MOVE N'WWI_Primary' TO N'C:\SQL\DATA\WideWorldImporters.mdf', 
MOVE N'WWI_UserData' TO N'C:\SQL\DATA\WideWorldImporters_UserData.ndf', 
MOVE N'WWI_Log' TO N'C:\SQL\Log\WideWorldImporters.ldf', 
MOVE N'WWI_InMemory_Data_1' TO N'C:\SQL\DATA\WideWorldImporters_InMemory_Data_1', 
NOUNLOAD, REPLACE, STATS = 5
GO

On SQL Server vNext 1.1, the output looks like this from the command above

5 percent processed.
10 percent processed.
15 percent processed.
20 percent processed.
25 percent processed.
30 percent processed.
Processed 1464 pages for database 'WideWorldImporters', file 'WWI_Primary' on file 1.
Processed 53096 pages for database 'WideWorldImporters', file 'WWI_UserData' on file 1.
Processed 33 pages for database 'WideWorldImporters', file 'WWI_Log' on file 1.

Converting database 'WideWorldImporters' from version 852 to the current version 860.
Database 'WideWorldImporters' running the upgrade step from version 852 to version 853.
Database 'WideWorldImporters' running the upgrade step from version 853 to version 854.
Database 'WideWorldImporters' running the upgrade step from version 854 to version 855.
Database 'WideWorldImporters' running the upgrade step from version 855 to version 856.
Database 'WideWorldImporters' running the upgrade step from version 856 to version 857.
Database 'WideWorldImporters' running the upgrade step from version 857 to version 858.
Database 'WideWorldImporters' running the upgrade step from version 858 to version 859.
Database 'WideWorldImporters' running the upgrade step from version 859 to version 860.
100 percent processed.
RESTORE DATABASE successfully processed 58455 pages in 6.105 seconds (74.803 MB/sec).

To make sure everything is cool after the restore is done, run the following

USE WideWorldImporters
GO
select [Website].[CalculateCustomerPrice](1,number,'20160101')
from master..spt_values
where type = 'p'
select [Website].[CalculateCustomerPrice](customerid,1,'20160101')
from Sales.customers

And now we can even check that the function is visible in the new sys.dm_exec_function_stats DMV

SELECT TOP 10 d.object_id, d.database_id, 
OBJECT_NAME(object_id, database_id) AS 'function name', 
 d.cached_time, d.last_execution_time, d.total_elapsed_time, 
 d.total_elapsed_time/d.execution_count AS [avg_elapsed_time], 
 d.last_elapsed_time, d.execution_count 
FROM sys.dm_exec_function_stats AS d 
ORDER BY [total_worker_time] DESC;

And here is the output

As you can see, we can see this function was executed a bunch of time

So there you have it, this is how you create the DB.... I also now understand why Brent Ozar uses the Stackoverflow DB for his posts, at least it is easy to find .., if you prefer that over this example, head over here: https://www.brentozar.com/archive/2015/10/how-to-download-the-stack-overflow-database-via-bittorrent/

AdventureWorksLT Sample Database Available For Download, Don't Forget To Attach The DB To See It

There is a new sample database available for SQL Server 2005. The name of this database is AdventureWorksLT , this database is a stripped down version of AdventureWorks.
You can download the installers for the AdventureWorksLT sample databases here
x86 AdventureWorksLT.msi -- 2,251 KB
x64 AdventureWorksLT_x64.msi -- 2,251 KB
Itanium (IA64) AdventureWorksLT_IA64.msi -- 2,251 KB

If you want to read more on the download page go here: http://www.microsoft.com/downloads/details.aspx?familyid=e719ecf7-9f46-4312-af89-6ad8702e4e6e&displaylang=en

Okay so you have downloaded the file and installed the database. But where is the database? You will have to attach the DB, you can use the wizard or this script below (make sure that you change the path and username, both are in bold font)

USE [master]
GO
CREATE DATABASE [AdventureWorksLT] ON
( FILENAME = N'C:\YourPathHere\MSSQL\Data\AdventureWorksLT_Data.mdf' ),
( FILENAME = N'C:\YourPathHere\MSSQL\Data\AdventureWorksLT_Log.ldf' )
FOR ATTACH
GO

if exists (select name from master.sys.databases sd where name = N'AdventureWorksLT' and SUSER_SNAME(sd.owner_sid) = SUSER_SNAME() )
EXEC [AdventureWorksLT].dbo.sp_changedbowner @loginame=N'LoginName', @map=false
GO

Now you can run these scripts to see how many tables, views, procedures and functions there are

SELECT TABLE_SCHEMA + '.' + TABLE_NAME AS FullTableName
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
ORDER BY FullTableName

-------------------------
dbo.BuildVersion
dbo.ErrorLog
SalesLT.Address
SalesLT.Customer
SalesLT.CustomerAddress
SalesLT.Product
SalesLT.ProductCategory
SalesLT.ProductDescription
SalesLT.ProductModel
SalesLT.ProductModelProductDescription
SalesLT.SalesOrderDetail
SalesLT.SalesOrderHeader

SELECT TABLE_SCHEMA + '.' + TABLE_NAME AS FullTableName
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'VIEW'
ORDER BY FullTableName

-------------------------------------
SalesLT.vGetAllCategories
SalesLT.vProductAndDescription
SalesLT.vProductModelCatalogDescription

SELECT ROUTINE_NAME
FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE ='FUNCTION'

-------------------------
ufnGetCustomerInformation
ufnGetSalesOrderStatusText
ufnGetAllCategories

SELECT ROUTINE_NAME
FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE ='PROCEDURE'

-------------------------
uspPrintError
uspLogError
