Thanks Kyle and John.

As is usually the case, once I see the SQL it's like "Oh, that makes sense."

Another curiosity question in this situation.

If I wanted a count of the number of invoices that have an item

I simply don't know enough to know what to google. Though I'm thinking

the count function will be in there twice . . .
