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 ?ThanksFranck
