Any suggestions on how I can get results back from a query rule where my value i

Here are a few ideas I can think of:

1. Use a query database node: ex. select <fieldA> from <table> where <fieldB> is not NULL
2. Create a view that filters the rows based on these null values. Then query that table.
3. Use a query rule to call back a bigger datasubset, then filter nulls in process.

There are positives and downsides to each scenario, so think about each one before implementing.
