- * Modified: using STL vector istead of CDynamicArray.
- *
- * Revision 1.5 2002/09/18 18:49:27 kholodov
- * Modified: class declaration and Action method to reflect
- * direct inheritance of CActiveObject from IEventListener
- *
- * Revision 1.4 2002/09/09 20:48:57 kholodov
- * Added: Additional trace output about object life cycle
- * Added: CStatement::Failed() method to check command status
- *
- * Revision 1.3 2002/06/11 18:21:52 kholodov
- * Fixed: column numbers are one-based for metadata
- *
- * Revision 1.2 2002/02/05 17:24:02 kholodov
- * Put into NCBI scope
- *
- * Revision 1.1 2002/01/30 14:51:23 kholodov
