Here's an example that executes 3 statements;
begin insert into foo values(1); insert into foo values(2); insert into foo values(3); end;

The block doesn't compile because temp_table doesn't exist at the point you're trying to compile the anonymous block. I'd recommend re-reading the doc link and forum link provided to get a better understanding of how temp tables work, as it's simply different with Oracle. You don't create Oracle temporary tables on the fly; you create them ahead of time and then just use them. The data itself is already specific to a particular session; you don't create and drop the table each time.
Also, you can't just "select * from table" in plsql. The results have to GO SOMEWHERE. Usually you'd either open a cursor and process it in the block, or send out a ref cursor if you want to send the data to a client side app. The ref cursor data wouldn't actually be fetched until the block completes though, so you'd need to use ON COMMIT PRESERVE ROWS, which would also mean you'd need to clean up the data yourself (delete the data from the table when you're done with it).
Corrections/comments welcome.
