This is what i expected in SQL query string:
SELECT dbo.FRIEND.FriendId, dbo.FRIEND.MemberId, dbo.FRIEND.FriendMemberId, dbo.FRIEND.DateAdded
FROM dbo.FRIEND INNER JOIN
dbo.MEMBER ON dbo.FRIEND.FriendMemberId = dbo.MEMBER.MemberId
WHERE (dbo.MEMBER.Activate = 1)
This is my entities with relationship : Entity Friend field
@Id
@Column(name = "[FriendId]")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long friendId;
@Column(name = "[MemberId]")
private Long memberId;
@OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name = "[FriendMemberId]")
private Member friendMember;
@Column(name = "[DateAdded]")
private Date dateAdded;
Entity Member field
@Id
@Column(name = "[MemberId]")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long memberId;
@Column(name = "[Activate]", columnDefinition = "boolean default true")
private boolean activate;
Here is my HQL query :
FROM Friend as f Left join f.Member as m WHERE f.MemberId = :memberId AND m.activate = true
but i got error. so how should i write HQL query get data and its condition depend on member.activate ?
You can access subtables using the dot notation and Hibernate will take care of the join for you.
SELECT FROM Friend f WHERE f.friendMember.activate = true
That's part of why HQL is so nice.
Your query has some typo. You should use field name instead of type when you access to field.
Try this:
FROM Friend as f Left join f.friendMember as m WHERE f.memberId = :memberId AND m.activate = true
If you have other problem. Please show me the log.
