ArcGIS Pro 3.1.1; Mobile Geodatabase
I have a table called TEST_TBL:

I can create a view on the table like this, using the Create Database View GP tool:
select
text_field,
case when text_field = 'a' then 'a' end as case_test
from
test_tbl
The resultset ought to look like this (DBeaver SQL Client):

But instead, the attribute table in ArcGIS Pro looks like this:

The value in the CASE_TEST field is incorrect. It should be 'a', but is being displayed as '1899-12-30'.
Why is that calculated CASE field being displayed incorrectly?
