Hey there
Just as in java - Creating a Scroll_Insensitive ResulSet using the SAP Hana JDBC Driver - Stack Overflow the answer is: the SAP HANA JDBC driver doesn't support any other resultset type than FORWARD_ONLY.
Would be interesting to know what your application needs the capability for to keep a result set open and scroll back and forth while making changes to it.
Note that JDBC doesn't actually require compliant drivers to provide this feature, so your relying on an optional feature here.
