How do I prevent fatal errors from qa_db_read_one_assoc?

Question

If I run qa_db_read_one_assoc on a query having no results, I get this fatal error:

Question2Answer fatal error:

Reading one assoc from empty results

Stack trace:

require() [path]/index.php:31

qa_db_read_one_assoc() [path]/qa-plugin/edit-history/qa-edh-revisions.php:48

Is there a way to prevent this? Shouldn't the function simply return null? I don't see any Q2A functions for getting the number of rows returned or anything.

Answer 1

See the second, optional, parameter :)

And thanks, somehow I missed the second parameter.
