server — might change at some point. Your ANSI code will more than likely run on the new database server;
however, code that is only T-SQL definitely will not.
In this chapter, you have gained a solid taste of making use of single table statements in T-SQL, but the
reality is that you often need information from more than one table. In the next chapter, we will learn
how to make use of JOINs to allow us to use multiple tables.
Exercises
1. Write a query that outputs all of the columns and all of the rows from the Product table (in the
Production schema) of the pubs database.
2. Modify the query in Exercise 1 so it filters down the result to just the products that have no
ProductSubcategoryID. (HINT: There are 209, and you will need to be looking for NULL values.)
3. Add a new row into the ProductLocation (in the Production schema) table in the Adventure-
Works database.
4. Remove the row you just added.
