I found that can use @Column annotation for execute subselect,
e.g

    private BigDecimal quantityOrders;

    @Column(name="(select 2 from dual) as quantityOrders",insertable = false, updatable = false)
    public BigDecimal getQuantityOrders() {
        return quantityOrders;
    }

I tested name with some select and all working. I can link to current table by name and all other in database. It is fantastic, but is it right ?

Where can I find any documentation for that ?

P.S.
In hibernate @Formula I can use 'this' for pointing current table, how do this here (it is important when define other alias e.g. when use CriteriaBuilder)
