運行以下程序是總是拋出一個異常：
Caused by: com.sybase.jdbc3.jdbc.SybSQLException: The datastream for token 236 should only be sent after other datastreams. It can not be a command datastream on it's own. This is an internal error.
具體方法為：
public List<?> executeProcedure(Class<?> entityClass, String procedure,
String requestId) {
List<?> list = new ArrayList<HibernateProcedureObject>();
try {
session = getCurrentSession(entityClass);
SQLQuery query = session.createSQLQuery(procedure);
query.setString(0, requestId);
list = query.list();
} catch (HibernateException e) {
e.printStackTrace();
logger.log(RMTManagementLevel.ERROR, e);
} finally {
this.closeConnection();
}
return list;
}
異常為：

解決方案：
只能利用傳統的Connection和ResultSet的形式：
resultSet = null;
try {
cstmt = getCurrentSession(entityClass).connection().prepareCall(
"{call " + procedure + "}");
resultSet = cstmt.executeQuery();
} catch (HibernateException e) {
this.closeConnection();
e.printStackTrace();
logger.log(RMTManagementLevel.ERROR, e);
} catch (SQLException e) {
this.closeConnection();
e.printStackTrace();
logger.log(RMTManagementLevel.ERROR, e);
}
