Subject [jira] Commented: (DERBY-1262) Like-predicates: % does not match tab character
Date Tue, 30 May 2006 14:04:31 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1262?page=comments#action_12413834 ] 

Håvard Mork commented on DERBY-1262:
------------------------------------

Thanks for your comment. The reason I didn't remove the old functions was due to metadata
upgrade. Since stored preparedstatements in EmbedDatabaseMetaData is referring to the old
functions, it wasn't immediately apparent to me how to deal with this.

But it is now my understanding that this is dealt with automatically by the upgrade mechanism?

I will make the changes.

> % 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
