I would expect to have to do a cast and/or coalesce to protect from type errors. The only saving grace is that the overall query isn't an error. Given the interaction with HTTP that would be problematic. There are two places aggregates can occur. In a SELECT expression, SUM(error) it leads to an unbound. In HAVING, it's a false. Andy
