I know this can be done; but not sure how (maybe using co-related subquery):

a. Transform the following query using only SELECT, FROM, and WHERE:

SELECT product, SUM(quantity) AS TotalSales
FROM Purchase
WHERE price > 1
GROUP BY product
HAVING sum(quantity) > 30;

b. Do you think any SQL query written using GROUP BY and HAVING clauses can be transformed to a query which only uses SELECT, FROM, and WHERE?

WITH cte AS ( your original query here without having)
SELECT * FROM cte where totalsales > 30
