SQL & PL/SQL

I created a table under my Oracle user from Alteryx, a third-party application.  In SQL Developer I can see the table under my user's schema and I can see all the data and properties.  However I cannot query it even when specifying the user (error: ORA-00942: table or view does not exist).

The following query correctly returned my user name:

select owner,

       object_name

from dba_objects

where object_name = any ('test_spread');
