Subject: binding a variable to NULL in perl-DBD

Greetings,

I'm trying to determine how to pass "NULL" to a variable, specifically in 
the conditional section of a SQL statement:

SELECT moo
FROM foo aa
WHERE field1 = ?
AND field2 = ?

Sometimes at the command line, when running the perl-DBD script, I would 
like the select statement to reflect:

SELECT moo
FROM foo aa
WHERE field1 = 'goo'
AND field2 IS NULL

Much thanks in advance,

Max Pyziur
