If you just want to compare whether the values of each hash are the same you could do : 
 
foreach my $v1 (values %sql) {
    foreach my $v2 (values %csv) {
        if ($v1 ne $v2) {
            # do something
        }
    }
}

There is probably a more efficient way, but I think this would do the trick.

EDIT: Thanks to cLive for pointing out that I'm totally on crack. Look at his post below for the good way to do this.
