I don't understand what you are asking here.  Can you explain a little
bit more?

This would not be a good idea.  If you return the connection to the pool
before you are done with all of the statements then the connection is
available for other processes to use.  If someother process uses the
connection while you are still using your statements then that other
process calls commit, it will commit your statements as well since they
all belong to the same connection.
