Whether you’re refining analytics for sales teams or reporting on user data, AI2sql is your shortcut to production-ready SQL—no coding required.

HAVING Syntax in PostgreSQL

How HAVING Works

HAVING is used with GROUP BY to filter aggregated results. Unlike WHERE, it applies conditions after grouping.

SELECT column, aggregate_function(column)
FROM table_name
GROUP BY column
HAVING aggregate_function(column) condition;

• HAVING works only after GROUP BY.

• PostgreSQL requires aggregate functions (e.g., COUNT(), SUM()).

HAVING Examples You Can Generate Instantly

1. Customers With More Than 10 Orders

SELECT customer_id, COUNT(order_id) AS total_orders
FROM orders
GROUP BY customer_id
HAVING COUNT(order_id) > 10;

2. Products With Sales Over $5,000

SELECT product_id, SUM(total_amount) AS total_sales
FROM sales
GROUP BY product_id
HAVING SUM(total_amount) > 5000;

3. Cities With Average Order Value Above $200

SELECT city, AVG(order_value) AS avg_order
FROM orders
GROUP BY city
HAVING AVG(order_value) > 200;
