HANA Optimal Performance issue ?

Hi,

1. How to create a materialized view? Is it possible in HANA? Will it be helpful?

2. Can anyone tell how to enhance performance of sql statements(stored procedures) in HANA by doing code optimization ?

   eg:  create procedure abc 

           as

           begin

               delete from schema.table where col = 'a';

               signal error;

            end

Thanks,

Rahul Anand
