Question: Show me the ID's from the products from supplier number 2 that are more expensive than this average, please.
SQL: SELECT T1.product_id FROM product_suppliers AS T1 JOIN products AS T2 ON T1.product_id   =   T2.product_id WHERE T1.supplier_id   =   2 AND T2.product_price  >   ( SELECT avg ( T2.product_price )  FROM product_suppliers AS T1 JOIN products AS T2 ON T1.product_id   =   T2.product_id WHERE T1.supplier_id   =   2 )
