I’m writing to see if we can come up with a clarification in what seems to be an ambiguity in the OVAL specification regarding SQL tests. Imagine that you are querying a database table, and some column that you want to check permits <NULL> values. If your query returns null values, how should that be expressed? Clearly we want to reflect the fact that there are results, but there’s no way to express a null value in an EntityItemFieldType. The problem with just creating an item with, for instance, a status of “does not exist” is that — well — it does exist. If you were to use a count function you’d end up getting a number that wouldn't match what the database itself would say. But, maybe that’s not important? Generally, this can be worked-around in the SQL query using statements like “coalesce”. Perhaps that should be documented as a best-practice? How do others deal with this?
