跨库操作SQL Server数据库的插入

create  procedure dbo.p_insertAmdata
as
declare @amid integer
declare @addate datetime
declare @msg varchar(80)
Declare mycursor cursor for select am_id from t_ammeter
open mycursor
fetch next from mycursor into @amid
while @@fetch_status=0
begin
  declare datecursor cursor for select max(ad_date) as maxdate from t_amdata
  open datecursor
  fetch next from datecursor into @addate
  select @msg='----------------------'+Str(@amid)+'---------------------------'
  if @addate<>null
  begin
  print @msg
  print @addate
  insert into t_amdata2 select * from OPENDATASOURCE(
         'SQLOLEDB',
         'Data Source=.;User ID=sa;Password=123'
         ).sdcs_data.dbo.t_amdata where am_id=@amid and ad_date>@addate
  end
  else

  end
  close datecursor
  deallocate datecursor

  fetch next from mycursor into @amid
end
close mycursor
deallocate mycursor

create procedure dbo.p_updatemeter--(
