I don't think so; I need multiple COUNT results for multiple
combinations; 5-8 persons isn't the only one. I also need counts for
1-4, 9-12 and 13 and up.
The output I currently get is something like this:
"persons 1-4" | 123
"persons 5-8" | 234
"persons 9-12" | 345
...
"LOCATION_NETHERLANDS" | 987
"LOCATION_BELGIUM" | 765
...
"washing machine" | 432
"dish washer" | 210
I don't see how I would get that with a HAVING clause. And I don't think
you can have multiple HAVING clauses...
The crux of the query is that I get all kinds of conditions counted -
with a single query, output as a single record.
