Answer 1

if you want to get a list of column names in an specific table, this is the sql query you need:

select rdb$field_name from rdb$relation_fields
where rdb$relation_name='YOUR-TABLE_NAME';

I tried this in firebird 2.5 and it works.

the single quotes around YOUR-TABLE-NAME are necessary btw

Answer 2

Get list of columns (comma-separated, order by position) for all table:

SELECT RDB$RELATION_NAME AS TABLE_NAME, list(trim(RDB$FIELD_NAME),',') AS COLUMNS
FROM RDB$RELATIONS
LEFT JOIN (SELECT * FROM RDB$RELATION_FIELDS ORDER BY RDB$FIELD_POSITION) USING (rdb$relation_name)
WHERE
(RDB$RELATIONS.RDB$SYSTEM_FLAG IS null OR RDB$RELATIONS.RDB$SYSTEM_FLAG = 0)
AND RDB$RELATIONS.rdb$view_blr IS null 
GROUP BY RDB$RELATION_NAME
ORDER BY 1
