Subject Parsing error for Fb 2.0 with derived tables?
Author Martijn Tonies
Arno forwarded me this:

SELECT
dt.*
FROM
(SELECT
r.RDB$RELATION_NAME,
rf.RDB$FIELD_NAME
FROM
RDB$RELATIONS r
JOIN RDB$RELATION_FIELDS rf ON (rf.RDB$RELATION_NAME =
r.RDB$RELATION_NAME)) dt

Error:
SQL error code = -206 Column unknown R.RDB$RELATION_NAME.DB_KEY At line 4,
column 30.

This is the SQL trace:

SELECT
dt.*
, "R.RDB$RELATION_NAME".RDB$DB_KEY
FROM
(SELECT
r.RDB$RELATION_NAME,
rf.RDB$FIELD_NAME
FROM
RDB$RELATIONS r
JOIN RDB$RELATION_FIELDS rf ON (rf.RDB$RELATION_NAME =
r.RDB$RELATION_NAME)) dt
