You can use SQL to retrieve information from your corporate database (providing, of course, that you understand its structure). This two-day introductory course will show you how to create tables in SQL Server, and then how to write SQL to extract information from them. You'll learn about the WHERE clause (for setting criteria); the ORDER BY clause; how to aggregate data using GROUP BY; and how to create inner, outer and full joins!
