Creating a Loop query in HANA Studio

Hi,

I need to test an application which kills running threads in HANA, so I am trying to create a query which stays IN LOOP for quite a big time (5 minutes or more). How should be my query?

I have tried creating an stored procedure with a WHILE command which increments a variable and it stops after reaching 999999, but unfortunately HANA differs from SQL and I am unable to create it.

Thanks in advance.
