i want to translate this code in phpmyadmin to laravel
SELECT AVG(valeur_5), id_client, nom_propriete, prenom_propreite, nom_entreprise, type_utilisatuer
FROM cliets c
INNER JOIN evaluations e on c.id = e.id_client
INNER JOIN users u on u.id = c.id_user
INNER JOIN propreites p on p.id_user = u.id
GROUP BY id_client
If you want to embed raw SQL into your program, just wrap it in a DB::select.
DB::select("SELECT AVG(valeur_5), id_client, nom_propriete, prenom_propreite, nom_entreprise, type_utilisatuer FROM cliets c INNER JOIN evaluations e on c.id = e.id_client INNER JOIN users u on u.id = c.id_user INNER JOIN propreites p on p.id_user = u.id GROUP BY id_client")
Alternatively, you can rewrite it with the Eloquent query builder.
try this:
$orders = DB::table('hrayfis')
->join('evaluations','evaluations.id_herfi','hrayfis.id')
->join('users','users.id','hrayfis.id_user')
->join('propreites','propreites.id_user','users.id')
->select(
DB::raw('avg(valeur_5)','propreites.nom_propriete '))
->groupBy('hrayfis.id')->get();

I'm struggling to convert this below MySQL query into laravel query builder. It has a lot of joins and subqueries inside. Can someone please help me?
MYSQL query:
SELECT a.id , b.*, a.agent_id, td.contacts, td.addresses
FROM teams a
left join team_details as td on td.team_id = a.id
LEFT OUTER JOIN
(
SELECT m.id, m.due_date, t.team_id, m.department, m.assigned_to , cm.title, u.name
FROM (
SELECT team_id, MAX(due_date) AS due_date
FROM campaign_activities where task_status=false and due_date is not null
GROUP BY team_id
) t JOIN campaign_activities m ON m.team_id = t.team_id AND t.due_date = m.due_date
left join campaign_activity_masters cm on cm.id = m.camp_activity_id
left join users u on u.id = m.assigned_to
) b ON a.id = b.team_id
order by a.id
I'm trying something like below but got stuck with LEFT OUTER JOIN as it has sub query inside :).
DB::table('teams as a')
->leftjoin('team_details as td', 'td.team_id','=','a.id')
->select('a.id', 'b.*', 'a.agent_id','td.contacts','td.addresses')
->leftouterjoin(DB::select(DB::raw('SELECT m.id, m.due_date, t.team_id, m.department, m.assigned_to , cm.title, u.name
FROM (
SELECT team_id, MAX(due_date) AS due_date
FROM campaign_activities where task_status=false and due_date is not null
GROUP BY team_id
) t JOIN campaign_activities m ON m.team_id = t.team_id AND t.due_date = m.due_date
left join campaign_activity_masters cm on cm.id = m.camp_activity_id
left join users u on u.id = m.assigned_to')))
->get();
Any suggestions, please? I want to apply paginate function paginate() instead of get() for this query builder.
I think you should try.
$cards = DB::select("SELECT a.id , b.*, a.agent_id, td.contacts, td.addresses
FROM teams a
left join team_details as td on td.team_id = a.id
LEFT OUTER JOIN
(
SELECT m.id, m.due_date, t.team_id, m.department, m.assigned_to , cm.title, u.name
FROM (
SELECT team_id, MAX(due_date) AS due_date
FROM campaign_activities where task_status=false and due_date is not null
GROUP BY team_id
) t JOIN campaign_activities m ON m.team_id = t.team_id AND t.due_date = m.due_date
left join campaign_activity_masters cm on cm.id = m.camp_activity_id
left join users u on u.id = m.assigned_to
) b ON a.id = b.team_id
order by a.id");
Hope it help you.
I can't get a left join to work in my prepared statement.
"SELECT DISTINCT(a.auto_id), m.merk, a.model, a.uitvoering, a.standaardtekst, a.prijs, a.prijs2, a.prijs3, a.handelsprijs, a.aanmaak, s.soort, z.prijs_id
/*,GROUP_CONCAT(DISTINCT(apc.NL) ORDER BY apc.NL ASC)*/
FROM autocom_new.auto_new a
INNER JOIN autocom_new.tbl_merken m
ON a.merk = m.merk_id
INNER JOIN autocom_new.tbl_soort s
ON a.soort = s.soort_id
INNER JOIN autocom_new.auto_zoekmachines z
ON a.auto_id = z.auto_id
/*
LEFT JOIN autocom_new.auto_accessoire acc
ON a.auto_id = acc.auto_id
LEFT JOIN autocom_new.tbl_autopricecode_new apc
ON acc.code_id = apc.code_id
*/
WHERE a.ac LIKE ? AND a.flag = ?"
The commented parts are the parts that aren't working.
I have no idea what I'm doing wrong.
EDIT
First of all I forgot that both tables have a column ac, so I've changed the where statement a bit. The left joins are working now, but the part in the select is still not working
So the problem was that I forgot a GROUP BY.

I have a complex query consisting of lots of Inner and Left Joins and i am attempting to get the number of record back in a certain table using the COUNT Function of SQL.
I am attempting to get the number of records in the 'held_proposals' table for each proposal using the proposal_id since I'll be outputting the data into a table using a foreach loop.
In essence I would like to show how many students have 'held' a proposal against each proposal.
This was my attempt:
SELECT p.proposal_id, p.proposal_title, p.description, u.user_record_id, u.forename, u.surname, c.course_title, h.*,
GROUP_CONCAT(DISTINCT t.tag_title) AS tags FROM proposal p
LEFT JOIN user u on u.user_record_id = p.user_record_id
LEFT JOIN course_details c on c.course_code = p.course_code
LEFT JOIN record r on r.proposal_id = p.proposal_id
LEFT JOIN proposal_tags pt on pt.proposal_id = p.proposal_id
LEFT JOIN tag_details t on t.tag_code = pt.tag_code
LEFT JOIN (
SELECT h.student_record_id, COUNT(*) AS Held
FROM held_proposals h
) H on h.proposal_id = p.proposal_id
WHERE p.source = "Supervisor"
AND (r.status_code not in (3,8) OR r.status_code IS NULL)
GROUP BY p.proposal_id;
the table currently looks like this:
I would like to add the value returned from the 'held_proposals' table for each proposal at the end of the table as another column.
Could any please provide me with some guidance as to how I can achieve this in the SQL query. Thank you in advance.
You need to group the count inside the query which you are joining something as
SELECT
p.proposal_id,
p.proposal_title,
p.description,
u.user_record_id,
u.forename,
u.surname,
c.course_title, coalesce(h.Held,0) as `Held`,
GROUP_CONCAT(DISTINCT t.tag_title) AS tags
FROM proposal p
LEFT JOIN user u on u.user_record_id = p.user_record_id
LEFT JOIN course_details c on c.course_code = p.course_code
LEFT JOIN record r on r.proposal_id = p.proposal_id
LEFT JOIN proposal_tags pt on pt.proposal_id = p.proposal_id
LEFT JOIN tag_details t on t.tag_code = pt.tag_code
LEFT JOIN (
SELECT proposal_id, COUNT(*) AS Held
FROM held_proposals group by proposal_id
) h on h.proposal_id = p.proposal_id
WHERE p.source = "Supervisor"
AND (r.status_code not in (3,8) OR r.status_code IS NULL)
GROUP BY p.proposal_id;
I have a select statement like this:
SELECT c.id AS courseid, u.id AS userid
FROM
mdl_user_enrolments ue
join mdl_enrol e on e.id = ue.enrolid
join mdl_user u on u.id = ue.userid
join mdl_course c on c.id = e.courseid
I have another piece of data I want that does not have a direct relationship with the current tables. I have been calling this function in the output loop,
function getLastCourseAccessByUser($courseid, $userid){
global $DB;
return
$DB->get_record_sql('
SELECT FROM_UNIXTIME(time, "%m/%d/%Y") as ftime
FROM mdl_log
WHERE course = '.$courseid.' AND userid = '.$userid.'
ORDER BY time DESC
limit 1
');
}
but would rather get all the data once, and not call back the db.
I am trying this:
SELECT c.id AS courseid, u.id as userid
(
SELECT FROM_UNIXTIME(time, "%m/%d/%Y") as ftime
FROM mdl_log
WHERE course = c.id AND userid = u.id
) AS lastaccessdate
FROM
mdl_user_enrolments ue
join mdl_enrol e on e.id = ue.enrolid
join mdl_user u on u.id = ue.userid
join mdl_course c on c.id = e.courseid
Or, could I call the function directly from the sql like this:
SELECT c.id AS courseid, u.id as userid,
'.getLastCourseAccessByUser(c.id,u.id).' AS lastaccessdate
FROM
mdl_user_enrolments ue
join mdl_enrol e on e.id = ue.enrolid
join mdl_user u on u.id = ue.userid
join mdl_course c on c.id = e.courseid
Thank you.
SELECT c.id AS courseid, u.id AS userid, FROM_UNIXTIME(t.time, "%m/%d/%Y") as ftime
FROM
mdl_user_enrolments ue
join mdl_enrol e on e.id = ue.enrolid
join mdl_user u on u.id = ue.userid
join mdl_course c on c.id = e.courseid
join mdl_log t on t.course = c.id and t.userid = u.id
You can put AND and OR clauses in a join in mysql so you can join on both your conditionals. Though you may want to make it an outer join so that it won't fail the entire query if the conditionals aren't met
Otherwise your sub select option should also work (this one)
SELECT c.id AS courseid, u.id as userid
(
SELECT FROM_UNIXTIME(time, "%m/%d/%Y") as ftime
FROM mdl_log
WHERE course = c.id AND userid = u.id
) AS lastaccessdate
FROM
mdl_user_enrolments ue
join mdl_enrol e on e.id = ue.enrolid
join mdl_user u on u.id = ue.userid
join mdl_course c on c.id = e.courseid
The more data you process on the MySQL Server side, the less traffic is generated between the MySQL Server and your PHP application, thus speeding up the application. I would say to get all the data from the server at once and not go back and forth too many times.
You can also create the getLastCourseAccessByUser function as a stored function in MySQL if you need to re-use it in other applications:
DELIMITER \\
DROP FUNCTION IF EXISTS getLastCourseAccessByUser\\
CREATE FUNCTION getLastCourseAccessByUser (in_course_id INT, in_user_id VARCHAR(50)
RETURNS STRING
BEGIN
SELECT FROM_UNIXTIME(time, "%m/%d/%Y") AS ftime
FROM mdl_log
WHERE course = in_course_id AND userid = in_user_id
ORDER BY time DESC
LIMIT 1
END\\
DELIMITER ;
Then you could use it in your SELECT statement:
SELECT c.id AS courseid,
u.id as userid,
getLastCourseAccessByUser(c.id,u.id) AS lastaccessdate
FROM mdl_user_enrolments ue
JOIN mdl_enrol e on e.id = ue.enrolid
JOIN mdl_user u on u.id = ue.userid
JOIN mdl_course c on c.id = e.courseid
I'm a little confused in here and need some help...
the situation is I've made three tables(fr_Leagues, fr_nations and fr_confeds), all i want to do is add a league which shows the name of the categories not the i.d with pagination. Here is the code:
NOW FIXED!
"SELECT
a.id as confed_id,
a.fr_short_name as confed_name,
b.id as nation_id,
b.fr_name as nation_name,
c.id as league_id,
c.fr_name as league_name"
." FROM fr_confeds as a
INNER JOIN fr_nations as b ON a.id = b.confed_id
INNER JOIN fr_leagues as c ON b.id = c.nation_id"
." LIMIT $paginate->start, $paginate->limit"
You are missing on how to link the different tables together. On each INNER JOIN, you need to have it:
INNER JOIN fr_nations ON a.<someColumn> = b.<anotherColumn> INNER JOIN fr_leagues ON a.<someColumn> = b.<anotherColumn>
USE THIS QUERY
SELECT * FROM fr_confeds as A
INNER JOIN fr_nations as B ON A.id = B.confed_id
INNER JOIN fr_leagues as C ON B.confed_id = C.league_id
LIMIT $paginate->start, $paginate->limit
