EclipseLink has extended support for stored procedure execution including:

  • IN, OUT and INOUT parameter support
  • CURSOR output parameter support
  • Result set support
  • Annotation support using @NamedStoredProcedureQuery
  • Dynamic definition support using StoreProcedureCall
  • Stored function support using StoredFunctionCall
  • Object-relational data-types, Struct, Array (OBJECT types, VARRAY), including mapping using ObjectRelationalDatatypeDescriptor
  • PLSQL types, BOOLEAN, RECORD, TABLE, using PLSQLStoredProcedureCall

A stored procedure call be used in any query to read objects, or read or modify raw data.

Any CRUD or mapping operation can also be overridden using a stored procedure call using a DescriptorCustomizer and the DescriptorQueryManager API.

Using JpaEntityManager createQuery() API to execute a stored procedure

import javax.persistence.Query;
import org.eclipse.persistence.queries.StoredProcedureCall;
import org.eclipse.persistence.queries.ReadAllQuery;
ReadAllQuery databaseQuery = new ReadAllQuery(Employee.class);
StoredProcedureCall call = new StoredProcedureCall();
Query query = ((JpaEntityManager)entityManager.getDelegate()).createQuery(databaseQuery);
List result = query.getResultList();
