Named parameters are query parameters that are prefixed with a colon (:). Named parameters in a query are bound to an argument by the following method:
javax.persistence.Query.setParameter(String name, Object value)
In the following example, the name argument to the findWithName business method is bound to the :custName named parameter in the query by calling Query.setParameter:
public List findWithName(String name) { return em.createQuery( "SELECT c FROM Customer c WHERE c.name LIKE :custName") .setParameter("custName", name) .getResultList(); }
Named parameters are case-sensitive and may be used by both dynamic and static queries.
