Hi Kshore,
are you asking regarding exception handling in SQLScript? If yes, then the answer is true. You can declare exit handlers for HANA standard SQL error codes and own defined error codes.
For detailed information please have a look to the documentation Exception Handling - SAP HANA SQLScript Reference - SAP Library. There are also some examples listed (Exception Handling Examples - SAP HANA SQLScript Reference - SAP Library).
Best Regards,
Florian
