How to create Read/Write Procedure in HANA

Hi,

How can I create a Read/Write Procedure in HANA

I need to create a stored procedure in HANA, in which I want to execute some DDL statements.

If I am not writing 'READS SQL DATA' in create procedure statement and executing some DDL statement inside procedure, then compilation error is coming.

Please suggest me what needs to be given in 'create procedure' statement so as to make that procedure as Read/Write procedure.

Thanks
