问在JDBC的常规/准备语句中可以安全地使用“Case语句”吗？

SELECT r.routineid, 
       r.routinetypeid, 
       CASE WHEN (pc.version=20 and pc.parentid>0) 
            THEN CASE WHEN (r.processed='t') 
                      THEN pc.processed ELSE r.processed 
                 END 
            ELSE r.processed 
       END AS processed, 
       CASE WHEN (r.version=2 and r.parentid>0) 
            THEN (SELECT m_req 
                    FROM routine 
                   WHERE routineid=r.parentid
                 )
