You are so close Bruce!
Actually I dont need to send data back to the database.
Thats done with a DataBrowser that displays and updates the entire database.
This is a separate entity that gets SOME data form the database IF the
daysLeft field in the database is less than a certain amount, 20 days
for example.
I want it to retrieve and only retrieve 4 fields form the database.
I would like to use a DataViewer as I think that would be easier, but
wasn't sure if the DataViewer could do that.
The user would click a button and a new form would show the data.
Sorry my code doesn't show the IF Then statement that is actually a
requirement that I'm seeking, oops my bad.

Got visibility?
Most devs has no idea what their production app looks like.
Find out how fast your code is with AppDynamics Lite.
