Create random string in ABAP CDS view

I would like to replace some ABAP logic with ABAP-CDS views. We don't have a HANA DB ( yet ) - so no SQL Script. Is there a way to create a random String with a defined length in ABAP-CDS?

This is a preparation for our HANA DB migration and should replace the function module "GENERAL_GET_RANDOM_STRING".

I want to "push down" as much logic as possible to the database, because we have about 16.000.000 entries where we need to enter a random string. And if this is created via Database this would be much faster.
