  What I use that differs from default:


   digits          | text                     | not null
   digits_prefix   | prefix_range             | not null
  Indexes:
      "idx_prefix" gist (digits_prefix gist_prefix_range_ops)


  I keep digits around so I can test both default  behavior and new behavior.  You only really NEED the second one.  


  On insert I set them to the same value (eg: 12145551212).


  End is fine.  Doesn't really matter.

      Read the part about how to define the table + the gist index.  The whole custom_sql thing assumes a familiarity with sql.  you can choose to not have a digits_prefix column and just change the datatype of prefix to prefix.  You can do what I did which is to have prefix be text and digits_prefix be of type prefix and a trigger to keep the two in sync.  the key is that you are searching against the prefix column for which there is a GIST index.

          it's the digits_prefix in the WHERE clause that's causing the error. 

          ur question re prefix+digits, it's explained in the Custom SQL portion in the wiki.

            ok so it needs also the alias l.digits in the condition I think.
            I'm a little confused about digits and prefix.
            if I check a number with the country code is it need to join
            prefix+digits ? how with this kinkd of sql request ?

            Thanks

              i think it's a typo. i changed digits_prefix to digits. to be sure, pls check the CREATE TABLE entries.

                I'm experimenting with mod_lcr with postgresql (8.4.4)
                there s an example of custom sql on wiki below :

    <profile name="use_prefix">
      <param name="custom_sql" value="
SELECT l.digits, c.carrier_name, l.${lcr_rate_field}, cg.prefix AS gw_prefix, cg.suffix AS gw_suffix,
       l.lead_strip, l.trail_strip, l.prefix, l.suffix, cg.codec, l.cid
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, ${lcr_rate_field} asc, random();
      "/>
    </profile>
however the query failed cause of digits_prefix field doesn't exist in the table.is it a typo ? or does it need a field concatenation of prefix and digits ?Thanks Franck
