In this practice session, you write queries that expand on the query developed in the Lesson 1 practice. The resulting query includes product, subcategory, and category names for products included in any subcategory that includes the word bike. In addition, you write a query to join the PurchaseOrderHeader table to itself to provide a list of pairs of purchase orders. Each row includes two purchase orders that have identical vendors and shipping methods.

Open a new query window in SSMS. In the existing query window, type and execute the following command to return information from the ProductSubcategory table, where the subcategory name includes the word bike:
USE AdventureWorks2008; SELECT ProductSubcategoryID, ProductCategoryID , Name AS 'Subcategory Name' FROM Production.ProductSubcategory WHERE Name LIKE '%Bike%' ORDER BY [Subcategory Name];
Notice that the result set includes a product category number but not a category name. In the existing query window, below the existing code, type, highlight, and execute the following code to join the ProductCategory table to the ProductSubcategory table to
Data Retrieval
retrieve the Name column from the ProductCategory table. You use an inner join because you are looking only for rows that are in common between the two tables:
SELECT ProductSubcategoryID, Production.ProductCategory.ProductCategoryID , Production.ProductSubcategory.Name AS 'Subcategory Name' , Production.ProductCategory.Name AS 'Category Name' FROM Production.ProductSubcategory INNER JOIN Production.ProductCategory ON Production.ProductCategory.ProductCategoryID = Production.ProductSubcategory.ProductCategoryID WHERE Production.ProductSubcategory.Name LIKE '%Bike%' ORDER BY [Subcategory Name];
You now add in the Product table so that you can see what products exist in each of these subcategories. In the existing query window, below the existing code, type, highlight, and execute the following code to join the product table into the existing query:
SELECT P.ProductID AS 'Product ID' , PSC.ProductSubcategoryID AS 'Subcategory ID' , PC.ProductCategoryID AS 'Category ID' , P.Name AS 'Product Name' , PSC.Name AS 'Subcategory Name' , PC.Name AS 'Category Name' FROM Production.ProductSubcategory AS PSC INNER JOIN Production.ProductCategory AS PC ON PC.ProductCategoryID = PSC.ProductCategoryID INNER JOIN Production.Product AS P ON P.ProductSubcategoryID = PSC.ProductSubcategoryID WHERE PSC.Name LIKE '%Bike%' ORDER BY [Subcategory Name];
Again, you use an inner join because only rows in common between the three tables need to be retrieved. In addition, because the schema and table names are long and are making the code difficult to read, you add table aliases to the query and reference the columns with the alias name.

Perform a Self-Join
In this exercise, you build a query that returns unique pairs of purchase orders that have the same vendor and shipping method. The report should not include the same pair of purchase order IDs more than once.
1. 2.
Open a new query window. In the existing query window, type and execute the following command to return pairs of purchase orders that have the same vendor and shipping method:
USE AdventureWorks2008; SELECT a.PurchaseOrderID , b.PurchaseOrderID
Lesson 2: Joining Related Tables
, a.VendorID , a.ShipMethodID FROM Purchasing.PurchaseOrderHeader AS a JOIN Purchasing.PurchaseOrderHeader AS b ON a.VendorID = b.VendorID AND a.ShipMethodID = b.ShipMethodID WHERE a.PurchaseOrderID < b.PurchaseOrderID;
In the existing query window, below the existing code, type, highlight, and execute the following code to make the result set easier to read by replacing the vendor IDs and shipping method IDs with their names:
SELECT a.PurchaseOrderID , b.PurchaseOrderID , v.Name , s.Name FROM Purchasing.PurchaseOrderHeader AS a JOIN Purchasing.PurchaseOrderHeader AS b ON a.VendorID = b.VendorID AND a.ShipMethodID = b.ShipMethodID JOIN Purchasing.Vendor AS v ON a.VendorID = v.BusinessEntityID JOIN Purchasing.ShipMethod AS s ON a.ShipMethodID = s.ShipMethodID WHERE a.PurchaseOrderID < b.PurchaseOrderID;
Save the script and close the query window. Leave SSMS open for the next practice.
Lesson Summary
The JOIN clause allows you to retrieve columns from related tables and group the results into a single result set. JOIN types include INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER, and CROSS. JOIN operators can combine more than two tables. A table can be joined to itself by defining different aliases for each reference to the table.
