declare @id1 int,@oldid int,@e_REcordid int ,@Olde_REcordid int
DECLARE price CURSOR
FOR SELECT id ,E_recordId FROM evaeve order by E_recordId desc
OPEN price
FETCH NEXT FROM price into @oldid,@Olde_REcordid
while @@fetch_status = 0
begin
FETCH NEXT FROM price
into @id1,@e_REcordid
if @Olde_REcordid=@e_REcordid
BEGIN
delete from evaeve where id=@id1
end
set @oldid=@id1
set @Olde_REcordid=@e_REcordid
end
close price
DEALLOCATE price
使用sql语句实现
复制代码 代码如下:
