SQL & PL/SQL

Is it possible to run stacked queries in Oracle SQL Developer???

Something like this...

SELECT *
FROM TABLE_1
;

SELECT *
FROM TABLE_2
;

SELECT *
FROM TABLE_3
;

And give my 3 different result sets in my Query Result window

I tried "BEGIN" and "END" and Oracle SQL Developer did not seem to like it.

Can someone let me know if this is possible and what the syntax might be???

Thanks in advance for your review and am hopeful for a reply.
