    临时表方式实现多条记录遍历

    declare @oper_cart_item_id bigint;
     declare @oper_cart_id bigint;
     declare @the_last_changed_date datetime;
     declare @oper_cust_id int;
     
     
         select * , 0 as flag into #shoppingcart_temp from deleted;
        while exists (select top 1 1 from #shoppingcart_temp t where t.flag = 0 )
        begin
      
        select top 1 
        @oper_cart_item_id = cart_item_id,@oper_cart_id = cart_id,
        @oper_cust_id = cust_id,@the_last_changed_date = last_changed_date
        from  #shoppingcart_temp where flag = 0 ;
    
        if @oper_cart_item_id is not null and @oper_cart_item_id <> 0 and left(@oper_cart_id,1) = '8'
        begin
           exec proc_sqlser_insertqueue @oper_cart_id,@oper_cart_item_id, @the_last_changed_date, @oper_cust_id, '3';
        end
      
        update  #shoppingcart_temp  set  flag = 1 where cart_item_id = @oper_cart_item_id
      end

    游标方式实现多条记录遍历
