The FROM clause identifies the table or view that contains the data and where the columns can be found As with all database objects, FROM clauses are fully identified with a four-part name: serverdatabaseschemaobject We would only use the four-part name when accessing an object on another server (such as when accessing a linked server) All other times, the local server is assumed The database is often omitted in the clause We first point to the database with the USE statement, and then can omit the database We can shorten the name to just a one-part name and identify only the object However, we frequently include the schema when identifying tables in the FROM clause because tables often have different schemas in SQL Server 2005 If a schema is not identified for the object, dbo is the default schema used This script shows how to pull columns from the PersonContact table:

USE AdventureWorks; GO SELECT Title, FirstName, LastName, EmailAddress FROM PersonContact;
NOTE In the preceding script, the first line is USE AdventureWorks This sets the context of the rest of the script to the AdventureWorks database If this is omitted, SSMS defaults to the Master database Since there is no Person Contact table in the Master database, the preceding script would fail if pointed at Master Once you have set AdventureWorks as the database context in your query window, you won t need to do so again in the same query sessionYour query window remains pointed at AdventureWorks In the following examples, the USE AdventureWorks line is omitted, but unless specified otherwise, we are still using the AdventureWorks database Later in this chapter, we ll show how we can combine multiple tables in the FROM clause using the ON predicate In this exercise, we ll start using the SELECT statement Imagine that someone is asking you to provide a listing of people in the database including their names and e-mail addresses

4 To change the column headers, add aliases to your statement with and without the AS keyword:
