Update on an insert trigger

[timscronin]

I would like to update a record in a table when a record is added. The dilema is I want to update the record I am adding. I tried an insert trigger ( it doesn't fail, it just doesn't update) If I use the same syntax in TSQL after the record has been inserted it handles the update properly. SO I think the syntax is OK. I have the trigger below. The question is - Is there a way to do this?
Thanks

CREATE TRIGGER transaction_ins_tr
ON dbo.transactions
FOR INSERT
AS
DECLARE @pat_id varchar(5),
@location_name varchar(50),
@account_id char(12),
@tran_num int
--get patient id
SELECT @pat_id = patient_id
FROM inserted
select @account_id = account_id from dbo.patient pa
where pa.patient_id = @pat_id
--get location
select @location_name = df_sitename from
development..patient_ dp
where dp.account_id = @account_id
-- update trans location
update dbo.transactions
set df_sitename = @location_name
where tran_num = @tran_num

I don't see a statement that sets the value of @tran_num. Thus the last update statement will not update anything because the value of @tran_num is null. Terry L. Broadbent - DBA
