CREATE TABLE SALES (sales_details VARCHAR, sales_transaction_id VARCHAR)
CREATE TABLE TRANSACTIONS (date_of_transaction VARCHAR, transaction_id VARCHAR, amount_of_transaction INT)

What are the sale details and dates of transactions with amount smaller than 3000?
SELECT T1.sales_details, T2.date_of_transaction FROM SALES AS T1 JOIN TRANSACTIONS AS T2 ON T1.sales_transaction_id = T2.transaction_id WHERE T2.amount_of_transaction < 3000
SELECT "T1"."sales_details", "T2"."date_of_transaction" FROM "SALES" AS "T1" JOIN "TRANSACTIONS" AS "T2" ON "T1"."sales_transaction_id" = "T2"."transaction_id" AND "T2"."amount_of_transaction" < 3000
