Stored Procedure in HANA Development perspective (XS Project)?

Hi,

How to create a procedure for performing DML operations  in SAP HANA Development perspective?

The default mode shows "READS SQL DATA" , which doesn't allow DML operations i.e. insert/update/delete/dynamic  sql..etc

CREATE PROCEDURE EMPLOYEE_DETAILS ( )

  LANGUAGE SQLSCRIPT

  SQL SECURITY INVOKER

  --DEFAULT SCHEMA <default_schema_name>

  READS SQL DATA

  AS

BEGIN

/*****************************

  Write your procedure logic

*****************************/

select * from employee;

END;

Could you please respond to this?

Thanks,

Sree
