How in this case to get access to the table?

Question

SQL

Hello! There is the following SQLrequest:

SELECT model, p FROM
(
   SELECT model, max(price) AS p
   FROM laptop
   GROUP BY model
   UNION
   SELECT model, max(price)
   FROM pc
   GROUP BY model
   UNION
   SELECT model, max(price)
   FROM printer
   GROUP BY model
) AS matherial

as a result it returns a table :
model | p
1121 | 850.0000
1232 | 600.0000
1233 | 980.0000
1260 | 350.0000
1276 | 400.0000
1288 | 400.0000
1298 | 1050.0000
1321 | 970.0000
1401 | 150.0000
1408 | 270.0000
1433 | 270.0000
1434 | 290.0000
1750 | 1200.0000
1752 | 1150.0000
My task is to select from this table modelwith the maximum price ... I tried to get it using

... AS matherial WHERE p IN (SELECT max(p) FROM matherial)

But apparently, the skuel interpreter does not see this matherial table at the WHERE execution stage, tell me pliz how can I display the model, by the way, the MODEL, without the price
