It does not aggregate (reduce number of rows) directly, but if you think well, at least the concept in Firebird should not aggregate directly, it should produce accumulated aggregation (necessary for window function running aggregation), so in fact is the engine that reduce numbers of rows. So SUSPEND in this context is very like JS YIELD with caller doing a reduce. I have even thought in use YIELD keyword in this context. Adriano
