Subject [jira] Commented: (DERBY-1623) Add ANSI TRIM implementation
Date Fri, 08 Jun 2007 17:47:26 GMT

Manish Khettry commented on DERBY-1623:
---------------------------------------

Sorry, I guess not all issues were addressed.

re: space vs tabs-- the new file AnsiTrimTest is all spaces I think. Please do not put any
tabs in there!
6-- trim in SQLChar/StringDataValue is not being generated by the code generator anymore.
However I do not know if there are existing triggers or query plans on disk which refer to
it so I did not remove it. If upgrade is not an issue then by all means the trim function
should go away or ansiTrim should just be named trim.
8. I hadn't thought of documentation but I could take a stab at it or atleast open a subtask
for it.
If it does make it to 10.3, then it should be buddy tested.
