Answer 1

the code below shows a way to do it in a loop it definetely needs a lot of editing, but i hope it helps.

        declare @RowId int
 declare @CategoryId int
        declare @CategoryName varchar(MAX)

 create table PART (RowId int, CategoryId int, CategoryName varchar)
 create table  NEWESTFOUR(RowId int, CategoryId int, CategoryName varchar, Image image)
        select RowId = ROW_NUMBER(),CategoryId,CategoryName into PART from [Category Table]


        set @PartId = 0
 set @CategoryId = 0 
 while @Part_Id <= --count
 begin
   set @PartId = @PartId + 1
          SELECT @CategoryId = category_id, @CategoryName = category_name from PART where PartId = @Part_Id
          SELECT RowId = @PartId, image,CategoryId = @category_id, CategoryName = @category_name   FROM item into NEWESTFOUR where category_id = :category_id 
ORDER BY date_listed DESC LIMIT 4

 end
 select * from NEWESTFOUR
 drop table NEWESTFOUR
        drop table PART
