# SQL HAVING Clause

### The SQL HAVING Clause

The HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.

#### HAVING Syntax

```sql
SELECT column_name(s)
FROM table_name
WHERE condition
GROUP BY column_name(s)
HAVING condition
ORDER BY column_name(s);
```

### Demo Database

Below is a selection from the "Customers" table in the Northwind sample database:<br>

![](/files/-LSc5cLqeovDTFZZc63U)

\
SQL HAVING Examples

The following SQL statement lists the number of customers in each country. Only include countries with more than 5 customers:

```sql
SELECT COUNT(CustomerID), Country
FROM Customers
GROUP BY Country
HAVING COUNT(CustomerID) > 5;
```

The following SQL statement lists the number of customers in each country, sorted high to low (Only include countries with more than 5 customer ):

```sql
SELECT COUNT(CustomerID), Country
FROM Customers
GROUP BY Country
HAVING COUNT(CustomerID) > 5
ORDER BY COUNT(CustomerID) DESC;
```

**Demo Database**

Below is a selection from the "Orders" table in the Northwind sample database:\ <br>

![](/files/-LSc6E0KvI9VxraKZzYY)

\
And a selection from the "Employees" table:<br>

![](/files/-LSc6N2yNnunk9PkobZu)

\
More HAVING Examples

The following SQL statement lists the employees that have registered more than 10 orders:

```sql
SELECT Employees.LastName, COUNT(Orders.OrderID)
 AS NumberOfOrders
FROM (Orders
INNER JOIN Employees ON Orders.EmployeeID 
 Employees.EmployeeID)
GROUP BY LastName
HAVING COUNT(Orders.OrderID) > 10;
```

The following SQL statement lists if the employees "Davolio" or "Fuller" have registered more than 25 orders:

```sql
SELECT Employees.LastName, COUNT(Orders.OrderID)
 AS NumberOfOrders
FROM Orders
INNER JOIN Employees ON Orders.EmployeeID 
 Employees.EmployeeID
WHERE LastName = 'Davolio' OR LastName = 'Fuller'
GROUP BY LastName
HAVING COUNT(Orders.OrderID) > 25;
```

\
NOTE: Whenever we want to apply filter condition in Aggregate functions, we use HAVING Clause. For Scalar Functions, we use WHERE Clause.
