I have the following Mysql query. Running as needed.
SELECT
t_doc.*, t_user.IDA, t_data.IDA
FROM
( SELECT DISTINCT IDau FROM t_doc ) IDau_list
LEFT OUTER JOIN
(
SELECT
IDd ,IDau
FROM
t_doc
WHERE
doc_type = 'doc'
GROUP BY IDau
)
doc_images ON doc_images.IDau = IDau_list.IDau
LEFT OUTER JOIN
(
SELECT
IDd ,IDau
FROM
t_auto_doc
WHERE
doc_type = 'jpg'
GROUP BY IDau
)
jpg_images ON jpg_images.IDau = IDau_list.IDau
LEFT OUTER JOIN
t_doc ON t_doc.IDdoc = COALESCE(jpg_images.IDd, doc_images.IDd)
LEFT OUTER JOIN
t_user ON t_user.IDau = t_doc.IDau
LEFT OUTER JOIN
t_data ON t_user.IDA = t_data.IDA
But, What I must bring this query to codeigniter Model, in which I have to adapt the query, as example like this...
$this->db->select('u.IDau, a.*');
$this->db->from('t_user u');
$this->db->join('t_doc d', 'd.IDau=u.IDau', 'left');
And ...More.....Here......
But, I got it difficult. Is some one out there might change it Please..
Thanks in advance
As #NEVERMIND Suggest I have accomplish the task using...
$query = $this->db->query("My QUERY WITH A BIT OF CHANGE");
Yes, I should make some change to get the exact Data as i needed.
Thanks for all of your comments and ideas.

What I thought would be very simple has turned out to be very complex. All I simply want to do is now total up the result into one row and column. In this case the sum would be 161. How do I do this? I've literally tried everything. I hope I've provided enough information.

Hello all StackOverFlow families.
I need your help about sql query in mysql. I join four tables but result is duplicate row.
I have tried by using GROUP BY but not work.
Here is my query:
SELECT `tbl_leave`.`id`, `tbl_leave`.`staff_id`, `tbl_leave`.`type_id`, `tbl_leave`.`start_date`, `tbl_leave`.`end_date`,
`tbl_leave`.`total_days`, `tbl_leave`.`reason`, `tbl_leave_type`.`type`, `tbl_employment`.`com_id` as `comid`, `tbl_staff`.`name`
FROM `tbl_leave` JOIN
`tbl_leave_type`
ON `tbl_leave_type`.`id` = `tbl_leave`.`type_id` JOIN
`tbl_employment`
ON `tbl_employment`.`staff_id` = `tbl_leave`.`staff_id` JOIN
`tbl_staff`
ON `tbl_staff`.`id` = `tbl_leave`.`staff_id`
You can look as picture: https://imgur.com/gallery/1Ewku
And this is relationship table: https://imgur.com/gallery/ziKq3
The result I want like this : https://imgur.com/gallery/6NJpR
Thank for your valuable times for this question.
Please try
SELECT distinct `tbl_leave`.`id`, `tbl_leave`.`staff_id`,
`tbl_leave`.`type_id`, `tbl_leave`.`start_date`, `tbl_leave`.`end_date`,
`tbl_leave`.`total_days`, `tbl_leave`.`reason`, `tbl_leave_type`.`type`,
`tbl_employment`.`com_id` as `comid`, `tbl_staff`.`name`
FROM `tbl_leave` JOIN
`tbl_leave_type`
ON `tbl_leave_type`.`id` = `tbl_leave`.`type_id` JOIN
`tbl_employment`
ON `tbl_employment`.`staff_id` = `tbl_leave`.`staff_id` JOIN
`tbl_staff`
ON `tbl_staff`.`id` = `tbl_leave`.`staff_id`;
Please try this solution and let me know if is there any problem occur:
SELECT [Columns] From tbl_staff as staff
JOIN tbl_employment as emp on staff.id = = emp.staff_id
JOIN tbl_leave as leave on staff.id = = leave.staff_id
JOIN tbl_leave_type as ltype on leave.type_id = = ltype.id
I have this SQL Query and at the moment I don't know how to build this with the larval query builder
SELECT h1.Name, h2.Torvorlage from
(SELECT Name, Player_ID FROM `Spieler` WHERE Vereins_ID = 1) h1
left JOIN
(SELECT Torvorlage, Player_ID FROM `SpielerStats` left join Spielplan on (SpielerStats.Spielplan_ID = Spielplan.Spielplan_ID) WHERE Spielplan.Spielplan_ID = 1 and Spielplan.Spieltag = 2) h2
on h1.Player_ID = h2.Player_ID
Can anyone give me a example how to build this?
Try this.
DB::table('Spieler')->where('Vereins_ID','=',1)
->join('SpielerStats','SpielerStats.Player_ID','=','Spieler.Player_ID','left')
->select('SpielerStats.Torvorlage','Spieler.Name')
->join('Spielplan','SpielerStats.Spielplan_ID','=','Spielplan.Spielplan_ID','left')
->where('Spielplan.Spielplan_ID','=',1)
->where('Spielplan.Spieltag','=',2)->get();
Or
$d = DB::raw('(SELECT Torvorlage, Player_ID FROM `SpielerStats` left join Spielplan on (SpielerStats.Spielplan_ID = Spielplan.Spielplan_ID) WHERE Spielplan.Spielplan_ID = 1 and Spielplan.Spieltag = 2) as h2')
DB::table('Spieler')
->select('Spieler.Name','h2.Torvorlage')
->leftJoin($d, 'h2.Player_ID', '=', 'Spieler.Player_ID')
->where('Vereins_ID','=',1)
->get();
In order to get a better answer, you should explain what your query is doing. What is the relationship with these tables? In my experience, when I had a complicated SQL query to convert to Eloquent, I found that defining the relationships on the models solved the problem.
I solved this with DB:Select
$spielerstats = DB::Select('SELECT h1.Name, h2.Torvorlage from
(SELECT Name, Player_ID FROM `Spieler` WHERE Vereins_ID = 1) h1
left JOIN
(SELECT Torvorlage, Player_ID FROM `SpielerStats` left join Spielplan on (SpielerStats.Spielplan_ID = Spielplan.Spielplan_ID) WHERE Spielplan.Spielplan_ID = 1 and Spielplan.Spieltag = 1) h2
on h1.Player_ID = h2.Player_ID');
I'm not sure if this is the best way but it works.
p = Patient.find(30)
p.patient_problems
The above code generates the following query
SELECT `patient_problem`.* FROM `patient_problem` WHERE `patient_problem`.`patient_id` = 30 AND (`patient_problem`.`record_status_id` = 1)
But is there any way to assign/use alias table_name like
p.patient_problems(:alias=>'p1') # just for Ex.. This code will not work
p.patient_problems(:alias=>'p2') # just for Ex.. This code will not work
So it will generate the following queries
SELECT `p1`.* FROM `patient_problem` AS `p1` WHERE `p1`.`patient_id` = 30 AND (`p1`.`record_status_id` = 1)
SELECT `p2`.* FROM `patient_problem` AS `p2` WHERE `p2`.`patient_id` = 30 AND (`p2`.`record_status_id` = 1)
Additional Info
My problem is when I try to use joins
p.patient_problems(:all,:joins=>joins)
I get this error
ActionView::Template::Error (Mysql2::Error: Not unique table/alias: 'patient_problem': SELECT `patient_problem`.* FROM `patient_problem` LEFT OUTER JOIN party on party.id = patient_problem.patient_id

left outer join user user1 on entered_by1.user_id = user1.id
left outer join party as party_user1 on party_user1.id = user1.person_id
LEFT OUTER JOIN patient_patient_search patient_patient_search1 on patient_patient_search1.patient_id = party.id
left join search search1 on patient_patient_search1.patient_search_id = search1.id

Ofcourse I could do some string manipulation on the generated joins query and set alias to patient_problem. But I thought setting alias for associations would be more cleaner since the joins query generated are unpredictable(in my scenario)
I am not sure what the variable joins is or how it was constructed. To alias tables in a join build your query like
Rails 3
PatientProblem.joins("as p1 OUTER JOIN patient_problem as p2 on ...")
or
PatientProblem.find(:all, :joins => "as p1 OUTER JOIN patient_problem as p2 ON ...")
you can make singleton methods for that and write the query one time and use may time like
def self.p1
#your active record query here.
end
and call like
PatientProblem.p1
Update
You can simply change the table name in your code:
Patient.table_name="p2"
I'm not sure if this would break anything else though ... so good luck!
Orignal Answer
One solution may be to define a separate model for each type of patient_problem and then do something like this:
class PatientProblem2 < ActiveRecord::Base
self.set_table_name "p2"
...
end
Another solution may be to use the ActiveRecord query interface which will allows for significant query flexibility:

Perhaps you can be more specific on the nature problem you are trying to solve.
I have the following SQL query
SELECT
DISTINCT
count("SiteTree_Live"."ID")
FROM
"SiteTree_Live"
LEFT JOIN "Page_Live" ON "Page_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "TourPage_Live" ON "TourPage_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "DepartureDate" ON "DepartureDate"."TourID" = "SiteTree_Live"."ID"
WHERE
("SiteTree_Live"."Locale" = 'en_AU')
AND ("SiteTree_Live"."ClassName" IN ('TourPage'))
AND ("DepartureDate"."DepartureDate" LIKE '2012-11%')
but it producing a wrong count as the query result. The total intented result this query is suppose to return should not be more than 245 but currently, its returning more than about "4569" results.
Thats is because of the JOIN on the "DepartureDate" table as the query returns the expected result when i remove the join from the "DepartureDate" table.
What modification do i need to make to my query to count the Macthes between "SiteTree_Live"."ID" and "DepartureDate"."TourID" whiles counting only the "SiteTree_Live"."ID" count excluding the Departure dates?
Any suggestions welcomed :)
THE ANSWER
SELECT
COUNT(DISTINCT SiteTree_Live.ID)
FROM
"SiteTree_Live" LEFT JOIN "Page_Live" ON "Page_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "TourPage_Live" ON "TourPage_Live"."ID" = "SiteTree_Live"."ID"
LEFT JOIN "DepartureDate" ON "DepartureDate"."TourID" = "SiteTree_Live"."ID"
WHERE
("SiteTree_Live"."Locale" = 'en_AU')
AND ("SiteTree_Live"."ClassName" IN ('TourPage'))
AND ("DepartureDate"."DepartureDate" LIKE '2013-03%')
Seems to give me the right result. Thanks for the tip #Michael Berkowski
Minor correction: if DepartureDate is a date-type, then the LIKE '2013-03% will force it to be coerced into a character type (this is a mysql feature) As a result, any indexes on DepartureDate will not be used, IIRC. Better use a plain range-query:
SELECT
COUNT(DISTINCT stl.ID)
FROM
SiteTree_Live stl
LEFT JOIN
DepartureDate dd ON dd.TourID = stl.ID
WHERE
stl.Locale = 'en_AU'
AND stl.ClassName = 'TourPage'
AND dd.DepartureDate >= '2013-03-01'
AND dd.DepartureDate < '2013-04-01'
;
Do this (You have a bunch of unneeded joins)
SELECT
COUNT(DISTINCT SiteTree_Live.ID)
FROM
`SiteTree_Live`
LEFT JOIN
`DepartureDate` ON `DepartureDate`.`TourID` = `SiteTree_Live`.`ID`
WHERE
`SiteTree_Live`.`Locale` = 'en_AU'
AND `SiteTree_Live`.`ClassName` = 'TourPage'
AND `DepartureDate`.`DepartureDate` LIKE '2013-03%'
You could also do a GROUP BY:
SELECT
COUNT(SiteTree_Live.ID)
FROM
`SiteTree_Live`
LEFT JOIN
`DepartureDate` ON `DepartureDate`.`TourID` = `SiteTree_Live`.`ID`
WHERE
`SiteTree_Live`.`Locale` = 'en_AU'
AND `SiteTree_Live`.`ClassName` = 'TourPage'
AND `DepartureDate`.`DepartureDate` LIKE '2013-03%'
GROUP BY
SiteTree_Live.ID
