Insert accumulated total to my table in SQL Server 2008 -


i want calculate running total (idd not primary or foreign key)

idd    svalue      acctotal 1       5             5 2       6             11 1       2             13 3       4             17 2       1             18

and on

i work in many trigger didn't work:

 create trigger acc on detail   update, insert         declare @accountid int      declare @getaccountid cursor       set @getaccountid = cursor         select idd         detail       declare @tot int      set @tot = (select sum(dvalues) detail)       open @getaccountid       fetch next @getaccountid @accountid       while @@fetch_status = 0      begin         print @accountid          update detail          set acctotal = @tot          fetch next @getaccountid @accountid      end       close @getaccountid

could not like:

@tot = (select top 1 isnull(acctotal, 0) + @newvalue detail order acctotal desc)

this work if you're ever dealing positive number though... advice unique order best way. adding seed column work order by.

regards

liam
