Textmatchning

["A B" <gentosaker@xxxxxxxxx>]

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.
