Re: Extract especific text from a sql statement

You already have most of the result columns, so the following should do it.

 SELECT pc.cod,
        pc.val,
        pi.qtd,
        COALESCE(pc.name, 'empty') AS name,
        lower(coalesce(pc.email, 'empty')) as email,
        status,
        c1.relname,
        c2.relname,
        pc.startdate
 FROM pc
 INNER JOIN pi on (pc.cod = pi.cod)
  JOIN pg_class c1 ON (c1.relname = 'pc' AND c1.relkind = 'r'
  JOIN pg_class c2 ON (c2.relname = 'pi' AND c2.relkind = 'r'
 WHERE pc.startdate > CURRENT_DATE
 order by 1 desc;
