Description

If i use constants like this :

SELECT object FROM MyObject object WHERE object.path LIKE '%|_%' ESCAPE '|'

all is ok, but if I want to use parameters - exception is thrown.

Example:

@Entity
@Table(name="simple_object")
public class MySimpleObject {

@Id
String Id ;

@Basic
@Column(name="value", nullable=false, length=36)
String value ;
.....................
.......................

EntityManager em = emf.createEntityManager() ;
Query q = em.createQuery("SELECT x FROM MySimpleObject x WHERE x.value LIKE ?1 ESCAPE '|'") ;
q.setParameter(1, "%|_%") ;
List<MySimpleObject> res = q.getResultList() ;

Exception in thread "main" <openjpa-1.1.0-SNAPSHOT-r422266:648359 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: Encountered "ESCAPE" at character 54, but expected: ["AND", "GROUP", "HAVING", "OR", "ORDER", <EOF>].
