Hi Dimitri,
I recreated your scenario in my HANA system , but could not reproduce the issue that you saw.
While running the query with the data that you provided . I got the below results which is expected.
select * from (
select t.id as id, t2.id as id2
from TE113926.test_table_view t
join test_table2_view t2
on t.value = t2.value
)
And running the query after the where clause , I got the below result which I think is the expected result. So I might be missing your issue all together.
select * from (
select t.id as id, t2.id as id2
from test_table_view t
join test_table2_view t2
on t.value = t2.value
)
where id2 is not null
and id2 = 1;
Also please remember as the views do not store the data and ID field in the view is a run time data the data values might change based on the run time values for the table.
Cheers!!
