I expect the following script would return a single row with a single column containing NULL, since TEST_TABLE is not populated.
Instead the computed column is returned.

CREATE TABLE TEST_TABLE
(
ID INTEGER,
COMPUTED_COL VARCHAR(6) COMPUTED BY ('FAILED')
);

SELECT t.COMPUTED_COL
FROM RDB$DATABASE r
LEFT JOIN TEST_TABLE t
ON r.RDB$RELATION_ID = http://t.ID

COMPUTED_COL
------------
FAILED
