关于model生成的疑问

1、以order服务homestayOrderModel为例，生成了包括Trans、SelectBuilder、FindSum等方法，这些方法是如何生成的？ 2、对于一些复杂的SQL查询，例如多张表的查询，在go-zero中是怎么操作的？是否可以使用gorm、xorm等去实现？

homestayOrderModel interface {
        Insert(ctx context.Context, session sqlx.Session, data *HomestayOrder) (sql.Result, error)
        FindOne(ctx context.Context, id int64) (*HomestayOrder, error)
        FindOneBySn(ctx context.Context, sn string) (*HomestayOrder, error)
        Update(ctx context.Context, session sqlx.Session, data *HomestayOrder) (sql.Result, error)
        UpdateWithVersion(ctx context.Context, session sqlx.Session, data *HomestayOrder) error
        Trans(ctx context.Context, fn func(context context.Context, session sqlx.Session) error) error
        SelectBuilder() squirrel.SelectBuilder
        DeleteSoft(ctx context.Context, session sqlx.Session, data *HomestayOrder) error
        FindSum(ctx context.Context, sumBuilder squirrel.SelectBuilder, field string) (float64, error)
        FindCount(ctx context.Context, countBuilder squirrel.SelectBuilder, field string) (int64, error)
        FindAll(ctx context.Context, rowBuilder squirrel.SelectBuilder, orderBy string) ([]*HomestayOrder, error)
        FindPageListByPage(ctx context.Context, rowBuilder squirrel.SelectBuilder, page, pageSize int64, orderBy string) ([]*HomestayOrder, error)
        FindPageListByPageWithTotal(ctx context.Context, rowBuilder squirrel.SelectBuilder, page, pageSize int64, orderBy string) ([]*HomestayOrder, int64, error)
        FindPageListByIdDESC(ctx context.Context, rowBuilder squirrel.SelectBuilder, preMinId, pageSize int64) ([]*HomestayOrder, error)
        FindPageListByIdASC(ctx context.Context, rowBuilder squirrel.SelectBuilder, preMaxId, pageSize int64) ([]*HomestayOrder, error)
        Delete(ctx context.Context, session sqlx.Session, id int64) error
    }
