the class QBSelect method having.

/**
 * Get the having-part of the query, used to add conditions.
 * The conditions added here are AND-ed.
 * @sample
 * var query = datasources.db.example_data.orders.createSelect();

 * .root.having.add(query.joins.orders_to_order_details.columns.quantity.count.eq(0))
