Håvard Mork updated DERBY-1262:
-------------------------------
Attachment: 1262_4.diff
Attached new patch with corrections (thanks, Bernt)
- using the more efficient stringbuffer.setLength for null-char padding
- esc (0x1b) as control char in test case, to avoid potential future tab->space
conversion.

> % in like predicates does not seem to match tab character. In the following
> example all whitespace in character literals is the tab character:
> ij> create table t4(i integer primary key, j integer, c varchar(10));
> 0 rows inserted/updated/deleted
> ij> insert into t4 values (1, 1, 'abc def');
> 1 row inserted/updated/deleted
> ij> select * from t4 where c like 'abc%';
> I |J |C
> ----------------------------------
> 0 rows selected
> ij> select * from t4 where c like 'abc %';
> I |J |C
> ----------------------------------
> 1 |1 |abc def
> 1 row selected
