    The HAVING clause can be used to restrict rows. It is similar to the WHERE condition except HAVING can include the aggregate function; the WHERE cannot do this.

    The HAVING clause behaves like the WHERE clause, but is applicable to groups. In this example, we use the HAVING clause to exclude the groups with the province ‘BC’.

    SELECT au_fname AS ‘Author”s First Name’, province as ‘Province’
    FROM Authors
    GROUP BY au_fname, province
    HAVING province <> ‘BC’
