Hi David,
I ended up doing what you suggest, and it seems to work OK right now. I'll definitely look for return_next in 8.1.
On a related subject, is there any interest in eliminating the requirement that types be specified at runtime,
either by the function returning the type, or in the select statement? It would be helpful to me, but it's not a
dealkiller.
Anyway, thanks a lot for your help, it's much appreciated.
Eric

For 8.0, not exactly, although you can batch the entire rowset into an
array ref of hash references, then return that.
In the forthcoming 8.1 (CVS TIP), there is a return_next() method.
Cheers,
