Caused by: java.lang.IllegalStateException: Query argument creationDateTime not found in the list of parameters provided during query execution

I am trying to cover the case where the :creationDateTime is Null to get the same result as the following query “SELECT o FROM ExtraNetOrder o”. I searched it on the internet and found the solution by adding IS NULL, but it does not work in my case. Currently I am getting the following error:

Caused by: java.lang.IllegalStateException: Query argument creationDateTime not found in the list of parameters provided during query execution.

If the paramter :creationDateTime does not exist, then the query should be executed without the where parameter clause. In my table, I don’t have creationDateTime with the NULL value.

In the final query I have 3 paramter which I am passing to the query. for the simplicity I added just one paramter (creationDateTime).

I am using EclipseLink in the projekt.

@NamedQueries({
    @NamedQuery(name="order_by_filter_options", query="SELECT o FROM ExtraNetOrder o "
            + " WHERE :creationDateTime IS NULL OR :creationDateTime = '' OR o.creationDateTime >=:creationDateTime ")
})

-------------------
Query q = em.createNamedQuery("order_by_filter_options");
if (fromDate != null)
    q.setParameter("creationDateTime", fromDate);

@SuppressWarnings("unchecked")
List<ExtraNetOrder> orders = q.getResultList();

Answer

You need to set :creationDateTime to null if the fromDate is null. Just remove the if and always call q.setParameter("creationDateTime", fromDate);
