I am creating web blocks and functions because I don´t know how to create store procedures in the cloud personal environment. If I could create some them I could use better the full potential from OS.
You can't create stored procs in the personal environment. You don't have direct DB access, and if you try doing it through OS code (like an Advanced Query), the user that you are running as doesn't have the rights to do it.
The last thing Outsystems needs is for someone to take down the personal environents with a bad stored proc...
