Complex sql update

Hi,
I'm trying to update a key in tablea with tableb using the where there
are mulitple where criteria. I'm trying to avoid the sql cursors to do
update for each record.
Is there a way I can do that in the following statement:
update billing_detail_debit_card set bdp_id =
(
select b.bdp_id from billing_detail_participant b join
billing_detail_debit_card dc
on b.billing_proc_no = dc.billing_proc_no
and b.cust_no = dc.cust_no
and b.company_no = dc.company_no
and b.participant_id = dc.participant_id
)
where billing_detail_debit_card.billing_proc_no
(
select dc.billing_proc_no, dc.cust_no, dc.company_no,
dc.participant_id
from billing_detail_participant b join billing_detail_debit_card dc
on b.billing_proc_no = dc.billing_proc_no
and b.cust_no = dc.cust_no
and b.company_no = dc.company_no
and b.participant_id = dc.participant_id
) bdp_table
= bdp_table.billing_proc_no
and billing_detail_debit_card.cust_no = bdp_table.cust_no
and billing_detail_debit_card.company_no = bdp_table.company_no
and billing_detail_debit_card.participant_id = bdp_table.participant_id--BEGIN PGP SIGNED MESSAGE--

You're working overtime. You had it, but then added too much. Try
this:
UPDATE billing_detail_debit_card
SET bdp_id =
(SELECT bdp_id
FROM billing_detail_participant b
WHERE billing_proc_no = billing_detail_debit_card.billing_proc_no
AND cust_no = billing_detail_debit_card.cust_no
AND company_no = billing_detail_debit_card.company_no
AND participant_id = billing_detail_debit_card.participant_id )

which might result in setting bdp_id to NULL for many
rows in billing_detail_debit_card you don't wish to update,
since if the subquery does not yield any rows, its value will
be NULL.
UPDATES like this can often benefit from SQL Server's
proprietary UPDATE .. FROM syntax, which might look
something like this for the query you have:
UPDATE billing_detail_debit_card
FROM billing_detail_participant AS b
WHERE b.billing_proc_no = billing_detail_debit_card.billing_proc_no
AND b.cust_no = billing_detail_debit_card.cust_no
AND b.company_no = billing_detail_debit_card.company_no
AND b.participant_id = billing_detail_debit_card.participant_id
