The information you want to select to print in your report must be extracted from your project database. To do this, you provide a command that specifies exactly which database fields you want to print information about. These fields become the columns in your report. To specify the database fields on which you want to report, use the SELECT command and its subcommands.

You can further qualify your selection by using the WHERE command which specifies the values the selected fields should hold if they are to be extracted and printed in your report.
