Question

i have an entity like this:

public class Account{
    private String code;
    @ManyToOne
    private Account ledgerAccount;


    public String getCode(){
        return code;
    }

    public String getFullCode(){
        return ledgerAccount.getCode()+code;
    }
}

So, fullCode is a derived property, i want to use it in my hql queries, how can i achive this?

Answer 1

Create a property called fullCode in your model and annotate it like this:

@Formula(“ledgerAccount.code+code”)
private String fullCode;

and change your getFullCode() method to:

public String getFullCode() {
    return fullCode;
} 

And then in your HQL:

select * from Account where fullCode = ?
