Absolutely clear as mud :P

I think this might be what you're after

SELECT
docnum,
alias1,
alias2,
subclass_alias
FROM
docmaster
WHERE
subclass_alias = 'Inquiry'
AND alias1 IN
(
SELECT
alias1
FROM
docmaster
WHERE
subclass_alias = 'Reply'
AND
(
alias2 = 'Pending'
OR alias2 = 'Redraft'
)
)

THINK BEFORE YOU PRINT - Save paper if you don't really need to print this
