updating one table in sql via a query referencing two tables


i have the following query:


select a.opp_id, a.no_id, a.AddDate, a.contract, a.TerritoryName,
b.opp_id, b.reference_id, b.flag, b.actdate
from table1  a, table2  b where a.TerritoryName in
(
'21111',
'22222',
'23333',)
and a.AddDate >= '2009-11-01 15:00:55.000'
and a.Opp_ID = b.opp_id


I want to update the b.actdate = '2011-04-05 01:00:55.000'
in the query results above.


would it be

--update table2
set actdate = '2011-04-05 01:00:55.000'
where (select a.opp_id, a.no_id, a.AddDate, a.contract, a.TerritoryName,
b.opp_id, b.reference_id, b.flag, b.actdate
from table1  a, table2  b where a.TerritoryName in
(
'21111',
'22222',
'23333',)
and a.AddDate >= '2009-11-01 15:00:55.000'
and a.Opp_ID = b.opp_id

not sure I have update syntax right
