So i've a made a database for a fishing company. I need to know how I would select customers who have purchased over £20,000 worth of fish over three months, six months, nine months and annually. I want to use only the payment table I have which has in it: Payment ID, CustomerID, CardNumber, Date_Begin, Date_End and Fish Price.

SQL

SELECT
CUSTOMERS.ID
FROM CUSTOMERS
WHERE (SELECT SUM (PAYMENT .FISH_PRICE) FROM PAYMENT  WHERE PAYMENT.CUSTOMER_ID = CUSTOMERS.ID AND PAYMENT.DATE_BEGIN >= : DATE_BEGIN AND PAYMENT.DATE_END <= :DATE_END) > '20000'

Untested :)

Uuuups sorry only payment table

SQL

SELECT
PAYMENT.CUSTOMER_ID,
SUM(PAYMENT.FISH_PRICE)
FROM PAYMENT
WHERE PAYMENT.DATE_BEGIN >= :DATE_BEGIN AND PAYMENT.DATE_END <= :DATE_END
GROUP BY PAYMENT.CUSTOMER_ID
HAVING
SUM(PAYMENT.FISH_PRICE) > '20000'

Still untested :)
