This article demonstrates how to use a subreport to retrieve
data on the same report from two different databases. You can expand on this sample
by creating multiple subreports in a single report or use a subreport to run
separate and distinct queries against the same database but display the data in
a single report. There are many instances where subreports can give you the
flexibility you need when a simple SQL query cannot accomplish your goal. Good
luck on your project and happy coding.
