Can you please try an explicit cast to integer in your SQL. eg:

SELECT CAST( ID AS INTEGER ) ...

Because at the moment I cannot see out a "type 14" would get into a
variant from an integer field. I am just wondering whether IB6
dialect 3 may be doing something a little strange.

Another thought also crossed my mind. Are you using a SchemaCache,
and if so have you made sure you have cleared the cache since last
changing the table?

Just some thoughts.
