org.hibernate.hql.internal.ast.QuerySyntaxException: transaction is not mapped

I have an error like this : java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Transaction is not mapped [SELECT NEW model.DailyReport(SUM(c.amount), date(c.transactionTimestamp)) FROM transaction AS c GROUP BY date(c.transactionTimestamp)]
and here is my code :
String queryStr = "SELECT NEW model.DailyReport(SUM(c.amount), date(c.transactionTimestamp)) FROM Transaction AS c GROUP BY date(c.transactionTimestamp)";
TypedQuery<Transaction> query = entityManager.createQuery(queryStr, Transaction.class);
query.setFirstResult(offset);
query.setMaxResults(limit);
return query.getResultList();
Help me, BTW I'm new in JPA. Thx!
Edited :
Here is my Transaction Class :
#Table(name = "Transaction")
#Entity
public class Transaction implements Serializable{
#Id // ID
#Column(length = 32, nullable = false)
private String id;
#Column(length = 32, nullable = false)
private String srcAccountId;
#Column(length = 32, nullable = false)
private String dstAccountId;
private Double amount;
#JsonFormat(pattern = Json.JSON_FORMAT_TIMESTAMP)
#Temporal(TemporalType.TIMESTAMP)
private Date transactionTimestamp;
// Setter and Getter here
}
And here is my persistence.xml :
<?xml version="1.0" encoding="UTF-8"?>

I am trying to delete a record from database by executing remove operation on parent. Please find below snippet for the same.
public static void main(String[] args) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("jpa-test");
EntityManager entityManager = entityManagerFactory.createEntityManager();
Parent parent = entityManager.find(Parent.class, 15149);
entityManager.getTransaction().begin();
entityManager.remove(parent);
entityManager.getTransaction().commit();
}
I am getting below exception.Please find below stack trace :

The order of sql execution is wrong .Delete sql on parent is executed before child.
Currently i solved this by calling remove operation on child before parent. Is their any way through which i can delete child records by calling remove operation on parent.

How save entitiy in MSSQL from java with JPA?

I tried connect to MSSQL from java with JPA and save entity. I create Entity:
a database connection successful
#Entity
#Table(name = "QCCC_USER")
public class User implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name = "name", length = 32)
private String name;
#Column(name = "lastName", length = 32)
private String lastName;
#Column(name = "age")
private int age;
public User(String name, String lastName, int age) {
this.name = name;
this.lastName = lastName;
this.age = age;
}
public User() {
}
//other getters and setters
UserService :
public class UserService {
public EntityManager em = Persistence.createEntityManagerFactory("COLIBRI").createEntityManager();
public void add(User user){
em.getTransaction().begin();
em.persist(user);
em.getTransaction().commit();
}
}
and in main methos i tried save user:
public class Main {
public static void main(String args[]) {
System.out.println("Hello world");
UserService userService = new UserService();
User user = new User("Pavel", "Petrashov", 25);
userService.add(user);
System.out.println("save");
}
}
But I have error before saving. It is this error:

I tried mapping but not help. How do it?

Replace the following
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
with this
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
Or with this depending on your MSSQL Installation.
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServer2008Dialect"/>
Hope this helps.

You need to use DB specific Dialects.
You said you are using MSSQL DB but using MySQL dialect.
Change Dialect
org.hibernate.dialect.MySQLDialect to org.hibernate.dialect.SQLServerDialect.
It will work

Getting "java.sql.SQLException: No value specified for parameter" for a #GeneratedValue field

I'm using Hibernate 3.6.0 with Mysql 5.5.15. I have an entity with a #GeneratedValue ID field. When I try to persist the entity it throws exception: No value specified for parameter 5. The fifth parameter is the ID field. How can I fix this problem?
The entity class:
#Entity
#Table(name = "T_DEVICE_HISTORY")
public class DeviceHistory {
#Id
#Column(name = "ID")
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;
#Column(name = "DEVICE_ID")
private String deviceId;
#Column(name = "GUID", length = 36)
private String guid;
#Column(name = "UPDATE_DATE")
private Date updated;
#Column(name = "STATUS", nullable = false)
#Enumerated(EnumType.STRING)
private DeviceStatus status;
// getters,setters ...
#PrePersist
public void setInitialState() {
setUpdated(new Date());
}
}
The code persisting the entity:
DeviceHistory deviceHistory = new DeviceHistory();
deviceHistory.setGuid(guid);
deviceHistory.setDeviceId(deviceId);
deviceHistory.setStatus(DeviceStatus.INACTIVE);
entityManager.persist(deviceHistory);
The stack trace:

From your code I can see that the updateDate is missing... is tat nullable field ?
AUTO is default strategy so you can remove. and try the following equivalent definition..
#Id
#Column(name = "ID")
#GeneratedValue
private long id;

Change your entity as follows, you need to add default constructor.
#Entity
#Table(name = "T_DEVICE_HISTORY")
public class DeviceHistory implements java.io.Serializable {
public DeviceHistory(){
super();
id = null ;
}
#Id
#Column(name = "ID")
#GeneratedValue(strategy=GenerationType.AUTO)
private long id;

JPQL JPA access google datastore

My entity class :
public class ACCOUNT implements Serializable{
private static final long serialVersionUID = 1L;
#Id
#Column(name = "USERNAME")
private String Username;
#Column(name = "PASSWORD")
private String Password;
public ACCOUNT(String user,String pass)
{
this.Username=user;
this.Password=pass;
}
// geter and setter

Now persist account and it was successful
ACCOUNT ac=new ACCOUNT("admin","123");
em.persist(ac);
I checked
http://localhost:8888/_ah/admin
and yes ,there is ACOUNT entity with 1 record admin and 123
but when I use JPQL to get all entity , it returned null
Query q=new Query("SELECT ac FROM ACCOUNT ac");
List<ACCOUNT> list=q.getResultList();
even with
em.find(ACCOUNT.class,"admin");
return null too
Did i miss something ? Please help me , very grateful for your help
