  Some samples of how to do custom SQL:

    =============================================================
    PostgreSQL with contrib prefix module which supports fast
    prefix queries.  Ideal option.
    =============================================================
    <profile name="pg_prefix">
      <param name="custom_sql" value="
SELECT l.digits, c.carrier_name, l.rate, cg.prefix AS gw_prefix, cg.suffix AS gw_suffix, l.lead_strip, l.trail_strip, l.prefix, l.suffix
FROM lcr l JOIN carriers c ON l.carrier_id=c.id JOIN carrier_gateway cg ON c.id=cg.carrier_id WHERE c.enabled = '1' AND cg.enabled = '1' AND l.enabled = '1' AND digits_prefix @> '%q'
AND CURRENT_TIMESTAMP BETWEEN date_start AND date_end
ORDER BY digits DESC, random();
      "/>

    =============================================================
    PostgreSQL with contrib prefix module which supports fast
    prefix queries.  Ideal option.  Alternate syntax which requies
    a session but allows variable substitution.
    =============================================================
