Hi,
|| isn't the concatenation operator by default. If you want it to be set
sql_mode=PIPE_AS_CONCAT. Otherwise, use the CONCAT() function instead of
|| operator.

I ran into this case where a "like" expression is not evaluated correctly if
the pattern is an expression.
The example below shows a case where *AAA* is not considered *like 'A' ||
'%'*
Is this a known limitation? Or a bug?
create table lookup (
name varchar(60)
);
insert into lookup (name) values ('AAA');
select * from lookup where name like 'A%';
=> 1 record returned. OK
select * from lookup where name like 'A' || '%';
=> returns nothing. INCORRECT!
select * from lookup where name like ('A' || '%');
=> same as previous and returns nothing. INCORRECT!
I reproduced this problem on win32 using versions 5.1 and 5.5.10
Best regards,
Johan
