[firebase-br] Descricao do campo

[dodomr em terra.com.br]

Assim eu ate consigo chamar a descricao do campo, mas vem sempre null...


select r.rdb$field_name,
t.rdb$type_name,
f.rdb$field_length,
t.rdb$description,
f.rdb$validation_source
from rdb$relation_fields r
join rdb$fields f on f.rdb$field_name = r.rdb$field_source
join rdb$types t on f.rdb$field_type = t.rdb$type
where (r.rdb$relation_name='<tabela>') and
(t.rdb$field_name='RDB$FIELD_TYPE')
