Subject [jira] Commented: (DERBY-1262) Like-predicates: % does not match tab character
Date Wed, 31 May 2006 11:36:30 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1262?page=comments#action_12414032 ] 

Bernt M. Johnsen commented on DERBY-1262:
-----------------------------------------

Instead of the loop in padWithNulls, you could use StringBuffer.setLength(len) instead, e.g:

		StringBuffer buf = new StringBuffer(len).append(string);
                buf.setLength(len);
		return buf.toString();

> % 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
