Обсуждение: numeric data types

Hi all,

i have a question, is there any advantages in using numeric(1) or numeric(2)
in place of smallint?
is there any diff. in performance if i use smallint in place of integer?

Thanx in advance,
Jaime Casanova

Performance-wise, smallint is an order of magnitude better.

Assuming you steer clear of planner deficiencies, smallint should be
slightly faster (since it consumes less disk space), but the performance
difference should be very small. Also, alignment/padding considerations
may mean that smallint doesn't actually save any space anyway.
