Access Control Statements in Stored Procedures

Posted on Aug 08, 2016 at 11:47 AM 22 Views

Hi,

I have created a Odata service on Sys.Users view to expose the User details as a Service. I need to enhance the service to perform CUD (Create, Update and Delete) operations. For this, I'm using the Odata Exit features where I call different stored procedures for respective operations.

In the procedure, I would like to use Access Control Statements - Create User, ALTER User and DROP User. But the system doesn't suggest these keywords inside the Procedure.

Could you please suggest if my approach is correct ? If so, why is it the system not allowing to use these keywords. I tried using ALTER User and the error says - 'Alter is incorrect or misplaced'.

Any suggestions ?

Regards,

Naresh

    Hi Naresh ,

    I think it is related to dynamic sql.

    You cannot write plain vanilla create,alter or other DDL statements in sql script.


    Please search for dynamic sql in hana you will have n number of threads for these.

    have a look at these thread, it might help you.
