Join Simon Allardice for an in-depth discussion in this video Creating relationships in SQL Server Management Studio, part of SQL Server 2008 Essential Training.
I am going to go ahead and describe a one-to- many relationship between two of my own tables.…So I have two very-very simple tables here.…I have a product table, which has a few products in it right now.…It's got a ProductID as the unique key, the primary key for this.…That's automatically incrementing, ranging from roughly 1000 through 1013 right now, and…I also have an OrderItem table.…This itself has its own primary key, OrderItemID, that I don't really care…about, but it's got a place for a ProductID and this is going to become the foreign key.…
I'd like to be able to create multiple order items for each product so that…ProductID 1001 can be used several times if I deem it necessary.…That means our many-to-one relationship is one product, many order items.…So how do I make it?…Well I am going to close down these tables.…There are a couple of different ways I can do this.…One way would be to go to the Database Diagrams area, add a new satabase…diagram, grab the two tables that I'm interested in, OrderItem and Product, and I…

Q: I'm having problems installing the free Express R2 version of SQL Server on Windows XP. I tried 64-bit and 32-bit versions. In the videos, the author installs from a DVD. Do I need to do the same?
Q: The link to the installer for the AdventureWorks sample database, as shown in the Chapter 2 movie "Installing sample databases," no longer works. Where can I find the installer?
A: Microsoft has reorganized its site. The sample files are still there, but they're a bit harder to find. To install them:
1) Visit http://msftdbprodsamples.codeplex.com/.
2) Click the link to "SQL Server 2008 R2 OLTP."
3) Click the AdventureWOkrs2008R2 Data File link and agree to the conditions to download the MDF file.
4) Move the MDF file to your SQL Server Directory, usually located at C:\Program Files\Microsfot SQL Server\MSSQL 10_50.MSSQLSERVER\MSSQL\DATA.
5) Open the SQL Sever Management Studio and connect to your instance using an account with administrative privileges.
6) Attach the sample database by right-clicking the Databases folder in the Object Explorer and choosing Attach from the pop-up menu.
7) Click the Add button in the next menu and navigate to the MDF file in the Locate Database Files window that appears. Select it and click OK.
8) Remove the reference to the log file in the "AdventureWorks2008R2" database details: pane by selecting the Log entry and clicking removing.*
9) Click OK to return to SQL Server Management Studio and complete the attachment process.
*MDF files are the "data" files for SQL Server databases. They often come along with LOG files (ldf files). This one didn't so we need to REMOVE the reference to the non-existent log file. Select the second row in the lower section (it should say File Type: Log and Message: Not Found) and click the REMOVE button.
