Re: LIKE quandary

This was what I was going for, but frankly, you don't even have to escape the _. Just the replace causes it to not match. Order in the join is important.

create or replace table kevin.testlike1 (column1 char(20));
create or replace table kevin.testlike2 (column2 char(20));

insert into kevin.testlike1 values('0110 EXFN 01 ABCD');
insert into kevin.testlike2 values('0110 EXFN 01'),('____ EXFN 01');

select * from kevin.testlike1 t1,
kevin.testlike2 t2
where
t1.column1 like trim(replace(t2.column2,'_','\_')) concat '%'
escape('\');

I got it now. I'd have to replace all % and _ in one column and then
specify the ESCAPE on the LIKE clause.

Unfortunately, the mailing list corrupted the example you copied from the
SQL reference. Let's see if I have better luck.
SELECT *
FROM TABLEY
WHERE C1 LIKE 'AAAA+%BBB%' ESCAPE '+'

Thanks

You could specify an escape character for the wildcard characters like
this:

SELECT *
FROM TABLEY
WHERE C1 LIKE ?AAAA+%BBB%? ESCAPE ?+?
