In the MariaDB 10.2 beta, creating a view containing a simple window function seems to work, but attempting to use the view fails with

SQL Error (1356): View 'test.rowseq' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them

Here's a simple example

create or replace view rowseq as
select ROW_NUMBER() OVER (ORDER BY seq) ROWNUM, seq
from (select 1 as seq union all select 10 union all select 100 union all select 1000 )a;

select * from rowseq;

boom.
