Hi,

I need help to extract fields and tables from a sql statement.

Example:

SELECT pc.cod, pc.val, pi.qtd,
COALESCE(pc.name, 'empty') AS name, lower(coalesce(pc.email, 'empty')) as email,
status
FROM pc
INNER JOIN pi on (pc.cod = pi.cod)
WHERE pc.startdate > CURRENT_DATE
order by 1 desc
;

I need to return that:

pc.cod
pc.val
pi.qtd
pc.email
status
pc
pi
pc.startdate



can you help me ?
