Hi,
I want to use subquery in POJO Class.

example :

I have User class.

@Column
private String userName;
@Column
private String userCode;


And I have some other class like LoggedUsers

@Column
private String loggedUserCode;

@Column
private String loggedUserName;



In the above LoggedUsers pojo class, I want loggedUserName from User class.

Like;

Select (Select userName From User WHERE userCode = loggedUserCode ) FROM LoggedUsers

Better use a join instead:

Code:
SELECT
    u.userName
FROM LoggedUsers lu
JOIN User u ON u.userCode = lu.loggedUserCode


You can even map this SQL query to a DTO. Check out this article for more details.
