I need some basic help with setting up a one-to-one mapping and query. I know this should be all over the internet, but I could not find a good explanation/example

2 Tables:

place and place_info
place has a primary key called place_id
place_info has a foreign key called place_id and it references the place_id in the place table

@Entity
@Table(name="place")
public class Place 
{
    @Id
    @Column(name="place_id", nullable=false)
    private int placeId;

    @Column(name="name", nullable=false)
    private String name;

    @Column(name="category", nullable=false)
    private String category;

    @Column(name="submit_date", nullable=false)
    private Date submitDate;

    @Column(name="user")
    private String user;

@Entity
@Table(name="place_info")
public class PlaceInfo 
{
    @Id
    @Column(name="place_info_id")
    private int placeInfoId;

    @Column(name="address")
    private String address;

    @Column(name="city")
    private String city;

    @Column(name="state")
    private String state;

    @Column(name="phone")
    private String phone;

    @Column(name="hours")
    private String hours;

    @Column(name="submit_date", nullable=false)
    private Date submitDate;

    @Column(name="user")
    private String user;

    @OneToOne
    @JoinColumn(name="place_id", referencedColumnName="place_id")
    private Place place;


public List<PlaceInfo> findPlaceInfo(Criteria criteria) {

        StringBuilder string = new StringBuilder("select pI, p.name from PlaceInfo pI");

        string.append(" inner join Place p p.placeId");
        if(criteria.getId()!=null)
            string.append(" where p.placeId = :id");

        Query query = getSessionFactory().getCurrentSession().createQuery(string.toString());

        if(criteria.getId()!=null)
            query.setParameter("id", criteria.getId());

        List<PlaceInfo> placeInfo = query.list();

        return placeInfo;
    }

    This line provokes the error:

    string.append(" inner join Place p p.placeId");

    Correct is

    string.append(" inner join pI.place p");

    You don’t need to mention the name of the join column. It already is done in the annotation. And then for the inner join you don’t give the class but the member name.

    Nevertheless, this does not produce a list of PlaceInfo, because you also select p.name (which is superfluous).

    The correct code is

        StringBuilder string = new StringBuilder("from PlaceInfo pI");
    string.append(" inner join pI.place");
    if(criteria.getId()!=null)
        string.append(" where pI.place.placeId = :id");

    When you need the name of the place then you reference it like

    placeInfo.get(i).place.name

    (In your code placeInfo is a list of PlaceInfo instances, which is confusing. You’d better name it placeInfoList and use the name placeInfo only for single instances of PlaceInfo.)
