given the table:

CREATE TABLE dbo.TestIds
(
    TestID int not null,
    TestName varchar(50) not null
)
[download]

and stored proc w/ out parameter:

create proc dbo.GetTest(
    @pName varchar(50) = '',
    @pID   int = 0 out
)
as
set nocount on
begin
    select @pID = TestID from TestIds where TestName = @pName
    if ( @@rowcount = 0 )
    begin
        select @pID = isnull(max(TestID),0) + 1 from TestIDs
        insert TestIDs
        select TestID = @pID, TestName = @pName
    end
end
[download]

you can do this:

my $sql = '
declare @id int
exec GetTest ?, @id out
select GotID = @id
';
my $sth = $dbh->prepare($sql);
if ( $sth->execute('foo') )
{
    while (my $hash = $sth->fetchrow_hashref )
    { 
        foreach my $key (keys %$hash) { print $key . " => " . $$hash{$
+key} . "\n" if $$hash{$key}; };
    }
}

to get this output:
