using table types in HANA

Hi,

I am new to hana.  My Task is to convert some oracle plsql procedures to hana stored procedures.  The oracle procedure uses objects and table objects as parameters.  I have the following questions:

1.  Can we declare objects in HANA like the way we do in oracle?

2.  How to store data into a variable from a table type IN parameter in a stored procedure ? Can somebody share the sample code ?

Thanks,

RENOO
