SQL Server 2008 Multirow update query trigger

I need help - I am trying to create a trigger to do the following:

When I run the query shown below all the records in Tbl_Points are set to the first value it finds and thus not doing a muti-record update

Any assistance on what I am doing wrong is most welcome



BEGIN

use xxdatabase

      -- SET NOCOUNT ON added to prevent extra result sets from

      -- interfering with SELECT statements.

      SET NOCOUNT ON;

-- I need to update the Tbl_Points with the Trans_Date from the Tbl_Transaction_Asset_Latest

update Tbl_Points

-- The field to update is in table Tbl_Points field PDA_Notes5 and needs to use
-- Tbl_Transaction_Asset_Latest.Trans_Date

SET PDA_Notes5 = Tbl_Transaction_Asset_Latest.Trans_Date

 FROM Tbl_Transaction_Asset_Latest

--get records from tbl_transaction_Latest

 where (Tbl_Transaction_Asset_Latest.Point_ID = Tbl_Points.Point_ID and Clone_Id = 'C000000018'  AND EXISTS ((SELECT Tbl_Points.Point_ID FROM Tbl_Points WHERE Point_ID = Tbl_Transaction_Asset_Latest.Point_ID))

That exists-part seems to repeat the join you camouflaged in the where
update p
-- The field to update is in table Tbl_Points field PDA_Notes5 and needs to use
-- Tbl_Transaction_Asset_Latest.Trans_Date
SET p.PDA_Notes5 = t.Tbl_Transaction_Asset_Latest.Trans_Date 
FROM Tbl_Points  as p
inner join Tbl_Transaction_Asset_Latest as t on t.Tbl_Transaction_Asset_Latest.Point_ID = p.Point_ID
--get records from tbl_transaction_Latest
 where  t.Clone_Id = 'C000000018'  

Open in new window

<<When I run the query shown below all the records in Tbl_Points are set to the first value it finds and thus not doing a muti-record update>>
all the records --> then it is a multi-record update isn't it?

<<I need help - I am trying to create a trigger to do the following>>
Don't know where's your problem.

See here example on a multi-row trigger , look for the join with 'inserted' which represents the new values , use UPDATE() to test if the column is changed.

Thanks a ton - the query did not like the Tbl_Transaction_Asset_Latest but otherwise it worked perfectly.

The set command below
SET p.PDA_Notes5 = DATEADD(day,7,t.Trans_Time)
returns Oct  5 2012  1:21PM

Is there a way to convert this to mm/dd/yyyy on the fly?
