Examples of org.eclipse.persistence.queries.DatabaseQuery.prepareCall()

org.eclipse.persistence.queries.DatabaseQuery.prepareCall()
ADVANCED: Pre-generate the call/SQL for the query. This method takes a Session and an implementor of Record (DatebaseRow or XMLRecord). This can be used to access the SQL for a query without executing it. To access the call use, query.getCall(), or query.getSQLString() for the SQL. Note the SQL will have argument markers in it (i.e. "?"). To translate these use query.getTranslatedSQLString(session, translationRow). @see #getCall() @see #getSQLString() @see #getTranslatedSQLString(org.eclipse.persistence.sessions.Session,Record)
