sql - Delete more than 6 million rows so SLOW -


i have sp needs delete more 6 million rows.

i tried approach still execution time slow.

declare @continue bit = 1  -- delete ids not between starting , ending ids while @continue = 1 begin      set @continue = 0      delete top (10000) u        table1 u (readpast)           id = @id     ,         nid in (select nid #node group nid)      if @@rowcount > 0         set @continue = 1   end

any other suggestions?

your loop logic looks ok

as other have said @ application design
can use staging tables , able truncate

if table has fk , confident not going violate them disable fk , re-enable

if have delete trigger , need delete 6 million every day need reevaluate design

look @ optimizing select put in delete 

select top (10000) u   table1 u (readpast)   join #node      on u.nit = #node.nit     , u.id = @id
