It depends on the datatypes in use.

If you use a type like "CHAR(32)" it will always be right-padded with
spaces.  Whereas if you use a type like "TEXT" or "VARCHAR(32)" it will
be stored as you enter it (it may still have some trailling spaces.

Now, when you use the rtrim() function, but insert the result into a
CHAR(N) column, all those spaces will just be stuck straight back on
again.  This is likely to be what is happening in your case.

                    Andrew.
