Since TEST_TABLE is empty, the results should be NULL.
Changing the query to 'SELECT *' return the one row in RDB$DATABASE, and
the column TEST_TABLE.ID is NULL and the column TEST_TABLE.COMPUTED_COL
is "FAILED".
If TEST_TABLE is empty, how can anything result from a join?

Rick,
What do you think should be the expected result?
