Øystein Grøvlen commented on DERBY-2794:
----------------------------------------
I feel the introduction in the documentation is bit confusing:
"TRIM is a function that returns its first string argument with leading and/or
trailing pad characters removed. The second argument indicates whether
leading, or trailing, or both leading and trailing pad characters should be
removed. The third argument specifies the pad character that is to be removed."
If argument is to mean parameter, there is only one argument as far as I can
see. This argument is comprised of up to three variable parts.
If argument is to mean variable part of the parameter, there are three types of
arguments, but the numbering is confusing. The first argument is not
necessarily the source. It is the last argument that is the source.
