Hi folks
I've got a table of pieces of equipment.
One piece of equipment may be owned by another piece of equipment, and
may own multiple other pieces.
To hold the relationship I have a piece_pieces table holding the owner
(pp_id) part id and the owned part ids (pp_part).
I'v realised I can store this within the original table so I've added an
owner attribute. I need to now populate this now from the other table,
but I can't work out how.
I've got pieces table
p_id -- part id
p_owner -- new owner attribute
piece_pieces table
pp_id -- id of owner
pp_part -- id of owned
