Subject [jira] Created: (DERBY-3664) Trailing white space in varchar field is trimmed off.

Trailing white space in varchar field is trimmed off.
-----------------------------------------------------

                 Key: DERBY-3664
                 URL: https://issues.apache.org/jira/browse/DERBY-3664
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.4.1.3, 10.3.2.1, 10.3.1.4
         Environment: Win XP, Derby 10.4.1.3
            Reporter: Shawn Aucoin


When executing an insert statement with a varchar field containing trailing whitespace, the
trailing whitespace is removed.  This results in unique constraint issues.  If  index is not
unique, select * from login where login = 'first_test'  will return both records.  Preceeding
whitespace doesn't appear to be affected.  I tested this from IJ and from java api.  I included
an example below

CREATE TABLE LOGIN
(
	LOGIN_ID INT PRIMARY KEY,
	LOGIN VARCHAR(60),
);

CREATE UNIQUE INDEX LOGIN_LOGIN_IDX 
ON LOGIN (LOGIN DESC);

insert into login (LOGIN_ID, LOGIN) values (1, 'first_test');
insert into login (LOGIN_ID, LOGIN) values (2, 'first_test ');

Now, i fully admit that there is no logical reason for trailing whitespace, but it is client
data that i am dealing with and I may not be able to get it changed.  Thanks, derby is a sweet
product!
