A B ha scritto:
Hi.
I would like to compare two columns a and b and find all cases where
a is a part of b, like this
select * from mytable where a ilike b;
but that will not give me a row in the case when a = 'foo' and b='FOOTBALL'
and I want that to be a match.
So how do I rewrite my expression? I can't find any way to add % to
make it match the way I want.
It seems that the order is important.

select 'foo%' ilike 'FOOTBALL';
----------
f
but
select 'FOOTBALL' ilike 'foo%';
----------
t
