UNIOn ALL
SELECT 2 AS id, 4 AS price
UNIOn ALL
SELECT 3 AS id, 6 AS price
UNIOn ALL
SELECT 4 AS id, 8 AS price
), tmpTable AS (
SELECT a.*, ROW_NUMBER() OVER(ORDER BY a.id, b.number) AS px
FROM goods a, master.dbo.spt_values b
WHERe b.number BETWEEN 1 AND a.price AND b.type ='P'
)
SELECt * FROM goods a WHERe EXISTS(SELECt TOP 1 1 FROM tmpTable aa GROUP BY id HAVINg aa.id =a.id AND MAX(aa.px) <=15)
