Filtering post aggregation using HAVING

#1

Let us see how we can filter the data based on aggregated results using HAVING Clause.

  • Having clause can be used only with GROUP BY
  • We need to use function as part of HAVING clause to filter the data based on aggregated results.
SELECT order_item_order_id,
  sum(order_item_subtotal) AS order_revenue
FROM order_items
GROUP BY order_item_order_id
HAVING sum(order_item_subtotal) >= 500;
