I have these queries in my ORACLE SQL:
SELECT dep.airport AS DEPAIRPORT,
dep.scheduled AS SCHEDULED,
dep.ontime AS ONTIME,
arr.arrontime AS ARRONTIME FROM (SELECT AIRPORT,sum(FIRSTFLIGHT) AS FIRSTFLIGHT, SUM(OTPFIRSTFLIGHT) as OTPFIRSTFLIGHT, SUM(ZMDFIRSTFLIGHT) as ZMDFIRSTFLIGHT,
COUNT(SCHEDULED) AS SCHEDULED,COUNT(ONTIME) AS ONTIME, COUNT(SCHEDARR) AS SCHEDARR FROM (SELECT DEPAIRPORT as AIRPORT,
MAX(case when A.STATUS = 'Scheduled' and
A.ACTUAL_BLOCKOFF is not null then 1 else NULL END) as SCHEDULED,
MAX(case when ((A.ACTUAL_BLOCKOFF+ interval '7' hour) - (A.SCHEDULED_DEPDT+ interval '7' hour))*24*60 <= '+000000015 00:00:00.000000000' and
A.ACTUAL_BLOCKOFF is not null then 1 else NULL END) as ONTIME,
MAX(case when A.STATUS = 'Scheduled' and A.ACTUAL_BLOCKON is not null then 1 else NULL END) as SCHEDARR
FROM TABLEA A left join TABLEB B ON A.FLIGHTLEGREF = B.FLIGHTLEGREF
where A.SERVICETYPE IN ('J','G') and to_char(SCHEDULED_DEPDT + interval '7' hour, 'yyyy-mm-dd') between '2018-07-15' and '2018-07-21'
and A.LATEST_ARRIVALAIRPORT != A.SCHED_DEPARTUREAIRPORT and (SUFFIX != 'R' or SUFFIX IS NULL)
group by DEPAIRPORT, AIRCRAFTREG,SCHEDULED_DEPDT,ACTUAL_BLOCKOFF,ACTUAL_BLOCKON,AIRCRAFTTYPE,SCHEDULED_ARRDT)GROUP BY AIRPORT) dep
left join (SELECT sched_arrivalairport AS airport,
count(CASE

and those codes works perfectly when I compiled it in oracle sql developer. but when I converted to active record in code igniter the code didnt works. here is my converted code in php:
$CI->db->select("DEP.AIRPORT AS DEPAIRPORT,
DEP.scheduled AS SCHEDULED,
DEP.ontime AS ONTIME,
ARR.arrontime AS ARRONTIME");
$CI->db->from("(");
$subq3 = $CI->db->get_compiled_select();
//$CI->db->reset_query();
$CI->db->select("DEPAIRPORT,sum(FIRSTFLIGHT) AS FIRSTFLIGHT, SUM(OTPFIRSTFLIGHT) as OTPFIRSTFLIGHT, SUM(ZMDFIRSTFLIGHT) as ZMDFIRSTFLIGHT,"
. "SUM(SCHEDULED) AS SCHEDULED,SUM(ONTIME) AS ONTIME");
$CI->db->from("(SELECT DEPAIRPORT as DEPAIRPORT,

$CI->db->where("A.LATEST_ARRIVALAIRPORT != A.SCHED_DEPARTUREAIRPORT"); $CI->db->where(divertStatus());
if ($stnService == "dom"){
$CI->db->where("A.SCHED_DEPARTUREAIRPORT IN (".$domstn.")");
}
if ($stnService == "int"){
$CI->db->where("A.SCHED_DEPARTUREAIRPORT IN (".$intstn.")");

if(!is_null($date1) && !is_null($date2))

$CI->db->from("TABLEA A ");
if(!is_null($date1) && !is_null($date2))

$subq2 = $CI->db->get_compiled_select();
//$CI->db->reset_query();
$CI->db->query("$subq3 $subq1 LEFT JOIN ($subq2");
when I tried to compile the converted code it always produces result like this
Error Number: 904
ORA-00904: "DEP"."AIRPORT": invalid identifier
Did I miss something in my converted code ? Any suggestion would be appreciated. Thankss
You can try to use Codeigniter query() function. Try this:
$your_query = "paste here your ORACLE SQL";
$result = $CI->db->query($your_query)->result_array();
This function return array of results. Docs here https://www.codeigniter.com/userguide3...
