Field labels in the DB?

Where are the field labels? i see the responses but not questions when I do the following query:
mysql> select f.title, f.is_active, d.* from my_DB2012.wp_rg_form f, wp_rg_lead_detail d where d.form_id=f.id limit 2;

The result:
+----------------------------------+-----------+----+---------+---------+--------------+--------------------+
| title | is_active | id | lead_id | form_id | field_number | value |
+----------------------------------+-----------+----+---------+---------+--------------+--------------------+

Can anyone let me know where the labels are stored? Essentially I'm looking for a way to scrape the form data over to another DB and I need to know where this form data is stored.

Thanks in advance,
