RuoYu Zuo commented on TRAFODION-37:
------------------------------------

This is just the 1st step of implementing T2 rowset functionality. New Prepare(), Execute(), Fetch() codes will be added for the complete feature. And part of the interfaces between native and JAVA will be changed as well for transporting byte buffers instead of using Java object references.
