I have this JPA entity in a spring-boot v1.5.1 application
#Entity
#Table(name = "score")
public class Score implements Serializable {
#Id
#GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
#Column(name = "user_id",nullable = false)
private Long user;
#Column(name = "message_id",nullable = false)
private Long message;
#Column(nullable = false)
private Long value;
#Column(nullable = false)
private Date date;
which records a bunch of user scores by date. I have a simple SQL query which returns a grouped report
SELECT (SELECT fullname from user where id=s.user_id) as name,SUM(s.value) as total FROM score s
WHERE date >= '2017/03/01''
GROUP BY user_id ORDER BY total desc
To recreate this using the spring-data-jpa interface, I've defined this ScoreRepository which is using a Projection interface as a return type.
public interface ScoreRepository extends JpaRepository<Score, Long> {
#Query(value = "SELECT new c.b.a.service.datastore.model.LeaderScore(" +
"(SELECT fullname from beuser where id=s.user_id) as name,SUM(s.value) as total) FROM score s " +
"WHERE date >= '?1' GROUP BY user_id ORDER BY total desc",
nativeQuery = true)
List<LeaderScore> getLeaderBoard(Date from);
My nativeQuery returns the exact field names as per my LeaderScore projection interface
public interface LeaderScore {
String getName();
Long getTotal();
}
I get this error, which seems to indicate a Spel mapping error

I'm trying to use JPARepository in Spring Boot to delete records that are less than a certain date, for for a given userid
Should be something like this Delete * from [table] where expiration_date < [date] and userid = [userid]
I thought I should be able to use one of the automatically generated methods
int deleteByExpiryDateBeforeAndUser(Date date, User user);
But this is generating a Select and not a Delete. What am I doing wrong?
Update
Entity class
#Getter
#Setter
#ToString
#Entity(name = "refresh_token")
public class RefreshToken {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#OneToOne
#JoinColumn(name = "user_id", referencedColumnName = "id")
private User user;
#Column(nullable = false, unique = true)
private String token;
#Column(nullable = false)
private Date expiryDate;
public RefreshToken() {
}
}
Repository class
#Repository
public interface RefreshTokenRepository extends JpaRepository<RefreshToken, Long> {
Optional<RefreshToken> findByToken(String token);
#Modifying
void deleteByUserIdAndExpiryDateBefore(Long userId, Date expiryDate);
int deleteByUser(User user);
}
Here's how I'm calling it
#Transactional
public void deleteExpiredTokens(User user) {
refreshTokenRepository.deleteByUserIdAndExpiryDateBefore(user.getId(), new Date());
}
You see a select statement because Spring Data first loads entities by condition.
Then once entities became 'managed' Spring Data issues a delete query for each entity that was found.
If you want to avoid redundant SQL query - you have to consider #Query annotation.
Then your code will look like this:
#Repository
public interface RefreshTokenRepository extends JpaRepository<RefreshToken, Long> {
// ...
#Query(value = "DELETE FROM refresh_token WHERE user_id =:userId AND expiry_date < :expiryDate", nativeQuery = true)
#Modifying
void deleteByUserIdAndExpiryDateBefore(Long userId, Date expiryDate);
//...
}
I want find a way to get extra column that count my records and return it in 1 mapping entity with extra filed.
I tried #transient on field but it will not return value when query.
Then I remove #transient but get an exception when save.
Also I tried #Formula but received null pointer exception.
Here's my repository code:
#Query(value = "select id,account,session_id,create_time,count from query_history a join " +
"(select session_id sessionId,max(create_time) createTime,count(*) count from query_history group by session_id) b " +
"on a.session_id = b.sessionId and a.create_time = b.createTime where account = ?1 order by create_time desc",
countQuery = "select count(distinct(session_id)) from query_history where account = ?1",
nativeQuery = true)
Page<QueryHistory> findByNtAndGroupBySessionAndAction(String account, Pageable pageable);
entity code:
#Entity
#Table(name = "query_history")
#Data
public class QueryHistory {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column
private String account;
#Column
private Long sessionId;
#Column
private long createTime;
#Transient
private Integer count;
}
Sorry about my English and thanks a lot for any advice.
I solved the problem by projections spring-data-projections, in fact I tried this before but in my sql:
select id,account,session_id,create_time,count
which should be:
select id,account,session_id sessionId,create_time createTime,count
PS:
projection interface:
public interface QueryHistoryWithCountProjection {
Long getId();
String getAccount();
Long getSessionId();
long getCreateTime();
Integer getCount();
}

My application uses Hibernate 5.02 and Wildfly 10 with a PostgreSQL 9.5 database. I'm trying to enable a filter on a #OneToMany collection held within an entity that is constructed via a NamedQuery. Unfortunately, it seems as if the filter is just ignored. Here are the different components, redacted for ease of reading.
#NamedNativeQueries({
#NamedNativeQuery(
name = "getAnalystProcess",
query = "SELECT * FROM analysis.analystprocess WHERE id = :processId",
resultClass = AnalystProcessEntity.class
)})
#FilterDef(
name = "analystProcessUnanalyzedMsgsFilter",
parameters = { #ParamDef(name = "processIds", type = "integer"), #ParamDef(name = "analystIds", type = "integer") })
#Filter(name = "analystProcessUnanalyzedMsgsFilter", condition = "analystprocess_id IN (:processIds) AND id NOT IN (SELECT msg_id FROM analysis.analyzedmsg WHERE analyst_id IN (:analystIds) AND analystprocess_id IN (:processIds)) ORDER BY process_msg_id")
#Entity
#Table(name = "analystprocess", schema = "analyst")
public class AnalystProcessEntity implements JPAEntity {
public static final String GET_PROCESS = "getAnalystProcess";
public static final String MSG_FILTER = "analystProcessUnanalyzedMsgsFilter";
public static final String MSG_FILTER_PROC_ID_PARAM = "processIds";
public static final String MSG_FILTER_ANALYST_ID_PARAM = "analystIds";
private static final long serialVersionUID = 1L;
...

public class MsgEntity implements JPAEntity {
...
#ManyToOne(cascade = CascadeType.ALL, optional = false)

private AnalystProcessEntity process;
#Column(name = "process_msg_id")
private Integer processMsgId;
private void buildAnalystProcess() {
LOG.info("Building AnalystProcessEntity");
analystUser.getJdbcSession().enableFilter(AnalystProcessEntity.MSG_FILTER)
.setParameter(AnalystProcessEntity.MSG_FILTER_PROC_ID_PARAM, analystProcessId)
.setParameter(AnalystProcessEntity.MSG_FILTER_ANALYST_ID_PARAM, analystUser.getId());
Query query = analystUser.getJdbcSession().getNamedQuery(AnalystProcessEntity.GET_PROCESS)
.setParameter("processId", analystProcessId);
// Query query = analystUser.getJdbcSession().createNativeQuery("SELECT * FROM analysis.analystprocess WHERE id = :processId")
// .setParameter("processId", analystProcessId)
// .addEntity(AnalystProcessEntity.class);
analystProcess = (AnalystProcessEntity) query.getSingleResult();
CREATE TABLE analysis.analystprocess (
id SERIAL PRIMARY KEY,
name TEXT NOT NULL UNIQUE,
description TEXT,
created_date TIMESTAMP NOT NULL DEFAULT now(),
...
);
CREATE TABLE analysis.msg (
id SERIAL PRIMARY KEY,
analystprocess_id INTEGER NOT NULL REFERENCES analysis.analystprocess(id) ON DELETE CASCADE ON UPDATE CASCADE,
process_msg_id INTEGER NOT NULL,
constraint tbl_statusid_analystprocessid unique(status_id, analystprocess_id)
);
As seen above, I have also tried the filter on constructing the AnalystProcessEntity class via createNativeQuery instead of getNamedQuery and no luck.
I also added a defaultCondition with hardcoded values into the #FilterDef just to see if it would execute the default condition and it still didn't.
I've tried the #Filter above the entity definition as well as above the class definition. I even came across a blog post which made it sound like the condition references entity fields (variable names) and not table fields (column names). Trying to stick to Java naming conventions in the Entity and Postgres naming conventions in the table, so I tried switching the references in the condition and to no avail.
I have sql logging turned on in Hibernate and the condition doesn't show up anywhere, as if it's just simply being ignored.
Any help would be greatly appreciated!
So, the problem was that I had the #FilterDef applied to the wrong class. It was my presumption that because I was constructing the AnalystProcessEntity which holds the MsgEntity collection (which I am trying to filter), that the #FilterDef would be applied to the AnalystProcessEntity class. Instead, it needs to be applied to the entity that it's actually filtering (hindsight being 20/20, that's pretty obvious).
Also, the actual condition needed to be modified to use complete references within the sub-select query.
I hope this helps someone at some point...

Additionally, I ran into another problem with null's appearing in the collection, despite the fact that I am using an #OrderColumn, which I thought fixed that issue. It seems that with the use of the #Filter, null's are inserted in place of what ended up being filtered OUT (excluded).
I need assistance in troubleshooting a relationship / query with EclipseLink 2.5.x provider.
The relationship from ThreePhaseMotorInput to ValidationMessage is supposed to be a uni-directional OneToMany, i.e. each motor can have 0..n messages and in Java object graph ValidationMessage does not have a reference back to ThreePhaseMotorInput.
I am getting an error that JPA can't find the attributes that are part of the ValidationMessage class when accessed via ThreePhaseMotor. (See error text below)
Thanks for thinking about my question!

The problem seems to be in the following query: select m.approvedMotor, m.valMessages, m.valMessages.validationMsg, count(m.valMessages.id) from ThreePhaseMotorInput m group by m.valMessages.validationMsg.
That query should be a JPQL query, i.e a query where you specify entities and their Java properties. Also you must use JOINs if you want to jump to another entity's properties: m.valMessages.validationMsg is not correct, but INNER JOIN m.valMessages msg GROUP BY msg is correct.
So try the following query:
select m, COUNT(msg) from ThreePhaseMotorInput AS m LEFT JOIN m.valMessages AS msg GROUP BY msg.validationMsg
You can't use a path expression with a Collection value association.
The documentation says: JPQL Path Expressions
It is syntactically illegal to compose a path expression from a path expression that evaluates to a collection.
In your query, m.valMessages is illegal because it references a collection of ValidationMessages.
In the other hand, m.approvedMotor is legal because it is a single value association.
As suggested in Andrei response, you need to modify your query to add another path expression:
select msg.validationMsg, COUNT(m.id) from ThreePhaseMotorInput m JOIN m.valMessages msg GROUP BY msg.validationMsg
you should use JOINs if you want to jump to another entity's properties. try the following JPQL query
select m, COUNT(msg) from ThreePhaseMotorInput AS m LEFT JOIN m.valMessages AS msg GROUP BY msg.validationMsg
