CREATE TABLE TRANSACTIONS (transaction_id VARCHAR2, share_count VARCHAR2, transaction_type_code VARCHAR2)

What are the lot details of lots associated with transactions whose share count is bigger than 100 and whose type code is 'PUR'?
SELECT T1.lot_details FROM LOTS AS T1 JOIN TRANSACTIONS_LOTS AS T2 ON T1.lot_id = T2.transaction_id JOIN TRANSACTIONS AS T3 ON T2.transaction_id = T3.transaction_id WHERE T3.share_count > 100 AND T3.transaction_type_code = "PUR"
SELECT "T1"."lot_details" FROM "LOTS" "T1" JOIN "TRANSACTIONS_LOTS" "T2" ON "T1"."lot_id" = "T2"."transaction_id" JOIN "TRANSACTIONS" "T3" ON "PUR" = "T3"."transaction_type_code" AND "T2"."transaction_id" = "T3"."transaction_id" AND "T3"."share_count" > 100
