I want to compare two date in jpql query using the current date function
I got an error
Syntax error parsing [SELECT d FROM Dossier d WHERE d.depid=1 AND d.typeDossier = :tpd AND d.dateCreation < CURRENT_TIMESTAMP() + 5].
[105, 107] The left expression is not an arithmetic expression
This is my query:
public List<Dossier> getDossierFindAllParDepartementDBTECHandUrgen() {
return (List<Dossier>) em.createQuery("SELECT d FROM Dossier d WHERE d.depid=1 AND d.typeDossier = :tpd AND " +
"d.dateCreation < CURRENT_TIMESTAMP() + 5",
Dossier.class).setParameter("tpd", "Urgent").getResultList();
}
JPA supports function CURRENT_TIMESTAMP
https://en.wikibooks.org/wiki/Java_Persistence/JPQL#Functions
but will not work with arithmetic operations. You can solve the problem by using a parameter, for example
TypedQuery<Dossier> query = em.createQuery("SELECT d FROM Dossier d WHERE d.depid=1 AND d.typeDossier = :tpd AND " +
"d.dateCreation < :fiveDaysAhead",
Dossier.class);
Date myFiveDaysAhead = new Date(Calendar.getInstance().add(Calendar.DAYS_OF_YEAR,5).getTimeInMillis());//or something
query.setParameter("tpd", "Urgent");
query.setParameter("fiveDaysAhead", myFiveDaysAhead, TemporalType.TIMESTAMP);
It may also be possible to find vendor specific solutions, as i noticed in one other answer https://stackoverflow.com/a/18514326/2835455

String q = "select id from Calendar c " +
"where c.isActive = 1 and " +
"date_part('dow', '2017-09-19 13:23:23'::date) = c.frequencyValue)";
Query query = em.createQuery(q);
List results = query.getResultList();
If I include ::date, hibernate would complain because : conflicts with parameter, but if I don't, postgres will complain. Could not choose a best candidate function. You might need to add explicit type casts. What can I do?
https://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html#queryhql-expressions
as specified extract function should work if the underlying db supports them so:
extract(dow from date '2017-09-19 13:23:23');
should works
I have a Query to parse on JPA , some errors have happened . I want a right way to make this.
Original:
Query q = this.em.createQuery("SELECT e FROM Entity e WHERE e.codigo = :codigo ORDER BY e.data ASC");
My solution but doesn't work:
Query q = this.em.createQuery("SELECT e FROM Entity e WHERE e.codigo = :codigo ORDER BY to_date(e.data,'DD/MM/YYYY') ASC");
where e.data is a String like "01/01/2014"
Solved
I´d replaced it with a nativeQuery.
Then a had be able to use Oracle Date Function
I want filter by Time in jpql but I think that I´m not doing well.
SELECT e FROM Pedido e WHERE e.fechaEntrega = :fechaInicio AND e.horaEntrega < :horaEntrega and que.setParameter("horaEntrega", horaEntrega, TemporalType.TIME); but when i see return this not filter by horaEntrega. I'm using eclipselink 2.5 any idea???
I tryed use SELECT e FROM Pedido e WHERE e.fechaEntrega = :fechaInicio AND CAST(e.horaEntrega AS TIMESTAMP) < :horaEntrega and doesn´t work and if i try cast to Time says me that expected NUMBER and got DATE
It´s weird when I write SELECT in sql im using cast(cast(etretst as timestamp) as time) < '08:00:00' and this works fine. And when I write this say me that expected TIME not a DATE
I resolved SELECT SELECT e FROM Pedido e WHERE e.fechaPedido = :fechaInicio AND CAST(CAST(e.horaPedido AS TIMESTAMP) AS TIME) < :horaZona and parameter is que.setParameter("horaZona", new Time(horaPedido.getTime()).toString());
I am somewhat new to jpa. I have created a few simple queries. But now i have a problem with a simple query. I have an entity Payment with 3 columns(Id,Amount1,Amount2).
Now i want to find all the rows from Payment where Amount1+Amount2 is greater than somevalue.I tried something like:
Query query = getEntityManager().createQuery(
"Select p from Payment p WHERE p.Amount1 + p.Amount2 >' " + someamount +" ' ");
But it is not working. I tried using SUM also but that is only one column.
Can anyone help me with this.
Thanks.
Assuming your entity is properly defined, the following query should work just fine:
final BigDecimal threshold = BigDecimal.valueOf(1000);
TypedQuery<Payment> query = getEntityManager().createQuery(
"SELECT p FROM Payment p WHERE p.Amount1 + p.Amount2> :value",
Payment.class);
query.setParameter("value", threshold);
List<Payment> results = query.getResultList();
We need to make sure only results within the last 30 days are returned for a JPQL query. An example follows:
Date now = new Date();
Timestamp thirtyDaysAgo = new Timestamp(now.getTime() - 86400000*30);
Query query = em.createQuery(
"SELECT msg FROM Message msg "+
"WHERE msg.targetTime < CURRENT_TIMESTAMP AND msg.targetTime > {ts, '"+thirtyDaysAgo+"'}");
List result = query.getResultList();
Here is the error we receive:
<openjpa-1.2.3-SNAPSHOT-r422266:907835 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: An error occurred while parsing the query filter 'SELECT msg FROM BroadcastMessage msg WHERE msg.targetTime < CURRENT_TIMESTAMP AND msg.targetTime > {ts, '2010-04-18 04:15:37.827'}'. Error message: org.apache.openjpa.kernel.jpql.TokenMgrError: Lexical error at line 1, column 217. Encountered: "{" (123), after : ""
Help!
So the query you input is not JPQL (which you could see by referring to the JPA spec). If you want to compare a field with a Date then you input the Date as a parameter to the query
msg.targetTime < CURRENT_TIMESTAMP AND msg.targetTime > :param
THIS IS NOT SQL.
The JDBC escape syntax may not be supported in the version of OpenJPA that you're using. The documentation for the latest 1.2.x release is here: http://openjpa.apache.org/builds/1.2.2/apache-openjpa-1.2.2/docs/manual/manual.html#jpa_langref_lit .
The documentation mentioned earlier refers to the docs for OpenJPA 2.0.0 (latest): http://openjpa.apache.org/builds/latest/docs/manual/jpa_langref.html#jpa_langref_lit
That said is there any reason why you want to inject a string into your JPQL? What about something like the following snippet?
Date now = new Date();
Date thirtyDaysAgo = new Date(now.getTime() - (30 * MS_IN_DAY));
Query q = em.createQuery("Select m from Message m "
+ "where m.targetTime < :now and m.targetTime > :thirtyDays");
q.setParameter("now", now);
q.setParameter("thirtyDays", thirtyDaysAgo);
List<Message> results = (List<Message>) q.getResultList();
