Manish Khettry commented on DERBY-1623:
---------------------------------------
I'm thinking of adding an optional argument to the existing LTRIM and RTRIM
functions. This will be a string literal and is basically the set of chars to
trim.
RTRIM('abcxyzxx', 'zyx') => abc.
Also a new function TRIM with the same arguments as L/R TRIM which trims both
leading and trailing characters. If anyone has any thoughts let me know.
