Supertack för det snabba och utmärkta svaret!!

Detta verkar fungera:

 SELECT DISTINCT hand.id, SUM( forced.amount ), players.player_stack
FROM handdata_hand AS hand, handdata_players AS players, handdata_forced AS forced

WHERE players.hand_id = hand.id
AND forced.hand_id = hand.id
GROUP BY hand.id
HAVING (
(
players.player_stack /
 SUM( forced.amount )
)
BETWEEN 0
AND 5
)
