Answer 1

As I predicted then.
Below is extract from Oracle Documentation:-
Restrictions on Sequence Values You cannot use CURRVAL and NEXTVAL in the
following constructs:
A subquery in a DELETE, SELECT, or UPDATE statement
A query of a view or of a materialized view
A SELECT statement with the DISTINCT operator
A SELECT statement with a GROUP BY clause or ORDER BY clause
A SELECT statement that is combined with another SELECT statement with the
UNION, INTERSECT, or MINUS set operator
The WHERE clause of a SELECT statement
The DEFAULT value of a column in a CREATE TABLE or ALTER TABLE statement
The condition of a CHECK constraint
_Within a single SQL statement that uses CURRVAL or NEXTVAL, all referenced LONG_
_columns, updated tables, and locked tables must be located on the same database._
