2 Solutions for simple SQL programming

2.1 Defining domain models only

@DomainModel
public class Member {
    private String no;
    
    @Queryable
    private String name;
    private Integer gender;
    private String mobile;
    private String otherInfo;

    @Relation(relationType = RelationType.HAS_MANY)
    private List<Order> orders;
}

2.2 Query&Update methods

Member.countAll();
Member.count("id > ?", 10);
Member.queryByPrimaryKey(11);
Member.queryFirst("id = ?", 11);
Member.query("id > ?", 8);
Member.queryAll();
...

2.3 The relation query

Member.queryAll(Member.HAS_MANY_ORDERS);
Member.queryPrimary(1, Member.HAS_MANY_ORDERS);
Member.queryByName("demo", Member.HAS_MANY_ORDERS);
...

3 Solutions for complex SQL programming

Order.Table orderTable = Order.asTable();
Select select = new Select();

select.project(sum(orderTable.amount) / sum(orderTable.quantity) * $(100) )
    .from(orderTable)
    .groupBy(orderTable.productId);

Generated SQL below：

SELECT SUM(order.amount) / SUM(order.quantity)  * 100
      FROM orders AS order GROUP BY order.produc_id
