Panco,
The answer is no. If you do not specify explicitly which tablespace to create a table in, DB2 uses a complex algorithm (based on USE privaleges) to determine which tablespace it will place the table. And if you have more than one tablespace that will qualify, DB2 will just pick one.
Frankly, if I am creating production tables, I would perfer to make the explicit decision where to place them. That way I can manage them better.
I believe the reason that there is nothing like SET CURRENT SCHEMA for tablespaces, is that table creation is done many orders of magnitude less then queries.
