What are the number of the purchase details of transactions with amount bigger than 10000?, and I want to list by the X-axis in desc please.
SELECT purchase_details, COUNT(purchase_details) FROM Purchases AS T1 JOIN Transactions AS T2 ON T1.purchase_transaction_id = T2.transaction_id WHERE T2.amount_of_transaction > 10000 GROUP BY purchase_details ORDER BY purchase_details DESC
SELECT "purchase_details", COUNT("purchase_details") FROM "Purchases" "T1" JOIN "Transactions" "T2" ON "T1"."purchase_transaction_id" = "T2"."transaction_id" AND "T2"."amount_of_transaction" > 10000 GROUP BY "purchase_details" ORDER BY "purchase_details" DESC
