Adding Parameter Input to the Report
Example 9
Banded Reports obtain query results from the DataBlock to report on the contents of a
database. Other information not contained within the Report Query can be obtained and
inserted into your report, including items such as:
 Date and time the report was generated
 Information about the database connection such as DataSource name, Driver file
name and version, SQL format, etc.
 DataBlock name and path
 Report name and path
 Username and user type
 The search parameters chosen from the DataBlock form.
To obtain this information you need to add an expression field into the desired band
using methods you are now familiar with. This is done by clicking the “Add an
expression field” icon on the Band Report Editor toolbar, then clicking within the band
where you want the field to be placed.

The Expression dialog boxes above are displayed. From the Expression Wizard, click the
“Variable” button which displays the list of variables that can be inserted into the band.
Variables preceeded with a $ are system variables. Variables without the $ are items
selected from the DataBlock form used to create the report.
Adding the selections made within the
DataBlock form to the report provides
very useful background information used
