Subject [jira] Commented: (DERBY-1623) Add ANSI TRIM implementation
Date Mon, 26 Mar 2007 22:18:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12484245
] 

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.
