The <table> placeholder should be replaced with the name of a table in an existing database. The purpose of this exercise is simply to verify that you have connectivity with the data stored in your RDBMS. Most products include sample data, and that is the data you re trying to connect to. Check product documentation or check with the database administrator to verify whether a database exists that you can access. If not, you can download the SQL for the INVENTORY database from the download site http://www.osborne.com or http:// www.mhprofessional.com/category/ cat=112, and use it to create your database objects. If you re working in Oracle and the sample schemas were installed, you can execute the following statement:

To execute the statement, type it in the input window of SQL Server Management Studio and then click execute. If you re working in the MySQL command-line interface, simply type the SQL statement and press enter. Once you execute the statement, the results of your query appear in the output window. At this point, don t concern yourself with the meaning of each word in the SQL statement or with the query results. Your only concern is to make sure everything is working. If you can t execute the statement, check with your database administrator or the product documentation.

Try This Summary
As I said at the beginning of the exercise, it is different from most of the other ones in the book because you are basically on your own to establish connectivity with your RDBMS. Again, this is because SQL is a language standard, independent of RDBMS implementations, and vendor-specific issues are, for the most part, beyond the scope of this book. In addition, the methods used to connect to a database, the tools available to make those connections, and the way in which an RDBMS is set up vary from product to product, environment to environment, and even operating system to operating system. However, the time you take now to research which product you ll use and to make sure you can connect to data in an existing database will prove invaluable as you apply the information discussed in the rest of the book.
