hello,

I am going crazy on this one:

select * from foo where bar like '0101%' and foobar='03997';

works fine (1 result). HOWEVER:

select * from foo where bar like '0101%' and foobar=ANY(SELECT
'03997'::TEXT);

does not work at all (no result)...

shouldn't this work usually???

am i missing something?

thanks anyone

What's the datatype of foobar?  I'm betting it's char(n), and
you're losing in the second case because of (lack of) trailing
spaces.
