I succeed to make mod_lcr works with prefix and postgresql 8.4.4
I have also changed the type of digits as varchar(20) because pg doesn't
accept empty numeric field (unless you know a trick to do that).
Thanks for your patience

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
