MySQL HAVING Clause
The SQL HAVING Clause
The HAVING clause was added to SQL because the WHERE keyword cannot be used with aggregate functions.
HAVING Syntax
SELECT column_name(s)
FROM table_name
WHERE condition
GROUP BY column_name(s)
HAVING condition
ORDER BY column_name(s);

The following SQL statement lists the number of customers in each country. Only include countries with more than 5 customers:
SELECT COUNT(CustomerID), Country
FROM Customers
GROUP BY Country
HAVING COUNT(CustomerID) > 5;
SQL HAVING Examples With Desc

FROM Customers
GROUP BY Country

ORDER BY COUNT(CustomerID) DESC;
