Subj:   SQL Standard for the "%" wildcard on the LIKE predicate.
 
From:   Anomy Anom

<-- Anonymously Posted: Tuesday, December 09, 2003 19:05 -->

The % wildcard on the LIKE predicate causes non-standard behaviour.

create table test1000
(name char(10) );

insert into test1000 values ('NEW YORK');

/* The following correctly retrieves NEW YORK */

select * from test1000 where name = 'NEW YORK';

/* The following does not retrieve anything */

select * from test1000 where name like '%YORK';

/* When we append two spaces to the end, since name is defined as char(10), it retrieves NEW YORK correctly */

select * from test1000 where name like '%YORK  ';

Other databases don't exhibit this behaviour. Is this a bug, or is this how it's supposed to work?

Thanks.
