I've got a data set that i would like to allow the user to filter using
the a parameter i create. The values in my paramater list are "PASS",
"FAIL" and "ALL".
If the user selects "PASS" or "FAIL" then only records with those values
will be shown, but for "ALL" i want all records to be shown. I'm not sure
how to show all the records though. What's the best way for me to do
this? Thanks.
