This chapter drilled down on two tools for running T-SQL statements. Express SSMS is a rich graphical tool for running T-SQL statements. Express SSMS is especially designed for SQL Server Express, although you can use it to run T-SQL statements for other SQL Server 2005 editions and even other SQL Server versions, such as the MSDE version of SQL Server 2000. This chapter demonstrated many of the most important Express SSMS features, including how to Connect to different SQL Server Express instances Use three powerful designers for creating databases, tables, and views Write, save, and reuse T-SQL code s 3 through 8 examine in-depth T-SQL coding techniques that you can use from within Express SSMS (or any other query tool). The second tool covered in this chapter is the sqlcmd utility. This command-line application also runs T-SQL statements, but it offers no graphical user interface. The sqlcmd utility is especially designed for IT professionals and SQL Server power users. What the sqlcmd utility lacks in ease of use it compensates for by exposing an interface that makes it fast to invoke T-SQL statements without the overhead of a graphical user interface. In addition, the coverage of the sqlcmd utility included an example showing how to schedule the automatic running of sqlcmd tasks using the Windows Scheduled Tasks applet.

Starting with the query written in Listing 4-13, join the table a to the Person.Contact table to display the employee s name. The EmployeeID column joins the ContactID column. USE AdventureWorks; GO SELECT a.EmployeeID AS Employee, a.Title AS EmployeeTitle, b.EmployeeID AS ManagerID, b.Title AS ManagerTitle, c.FirstName, c.MiddleName, c.LastName FROM HumanResources.Employee AS a LEFT OUTER JOIN HumanResources.Employee AS b ON a.ManagerID = b.EmployeeID LEFT OUTER JOIN Person.Contact AS c ON a.EmployeeID = c.ContactID;

any database developers and business analysts have a way of taking databases for granted. These database users focus almost myopically on what s inside a database, such as its tables, stored procedures, and other database objects. However, before you can have a database application, someone, such as a DBA, lead developer, or power user, must create a database. The settings for a database at the time of its creation can significantly impact its suitability for different kinds of applications. These settings are often referred to as database meta data namely, data about a database, as opposed to what s in a database. Even after a database is initially created, you can tweak database meta data to optimize the performance of a database or repurpose a database to meet new objectives. This chapter presents the skills that you need to know to create and manage databases. You ll learn how to find the files that support a database and how to explore and manipulate database meta data. The content within this chapter trains you to create databases programmatically with T-SQL. You can run the T-SQL code from Express SSMS, which 2 introduced. This chapter also shows you how to attach database files copied from another computer. In addition, you ll learn how to apply XCopy deployment and constraints that can inhibit this SQL Server Express (SSE) feature from being available. This chapter concludes by training you to protect your valuable database assets through coverage of backup and restore techniques. The discussion of backup and restore scripts at the end of this chapter presents easy-to-follow commentary describing which clauses and argument values to use for specific recovery scenarios.

Before you create and manage databases, it is very helpful to learn about important database features and the different kinds of databases. This section provides a quick introduction to these topics. Databases are core objects inside of any SSE instance. In this section I briefly introduce databases, particularly as they pertain to SSE specifically and SQL Server 2005 generally. Another goal of this section is to highlight the interplay among XCopy deployment, the auto-close feature, and whether a database is attached to a database server. You ll also receive a quick overview of database types with a special focus on system databases. A basic understanding of these databases, particularly the master database, can help you avoid making disastrous mistakes or facilitate your recovery from what might otherwise be a fatal flaw.

Use the AdventureWorks2008 database to complete this exercise. 1. Using a subquery, display the product names and product ID numbers from the Production.Product table that have been ordered. SELECT ProductID, Name FROM Production.Product WHERE ProductID IN (SELECT ProductID FROM Sales.SalesOrderDetail); 2. Change the query written in question 1 to display the products that have not been ordered. SELECT ProductID, Name FROM Production.Product WHERE ProductID NOT IN ( SELECT ProductID FROM Sales.SalesOrderDetail WHERE ProductID IS NOT NULL); 3. If the Production.ProductColor table is not part of the AdventureWorks2008 database, run the code in Listing 4-11 to create it. Write a query using a subquery that returns the rows from the Production.ProductColor table that are not being used in the Production.Product table.
