I have 3 tables: Users, Properties, Units
User table:
user_id user_name
Properties table
pty_id pty_name user pty_status
Units Table
unit_id unit_name pty_id unit_status
i want to show user details , number of properties and units and their details.
Here is my query:
DB::statement('SET SESSION group_concat_max_len = 10485760');
$ar = DB::table('users as u')
->leftjoin('properties as p', function($join) {
$join->on('p.user_id', '=', 'u.user_id')->where('p.pty_status', '!=' ,0 );
})
->leftJoin(
DB::raw("
(select COALESCE(count(unit_id),0) AS cntunits, pty_id as temp_pty
from property_units as pu3
left join properties as p2 on pu3.unit_pty_id = p2.pty_id
where pu3.unit_status!=0
group by p2.pty_id) as temp"), 'p.pty_id', '=', 'temp.temp_pty')
->select(
DB::raw("group_concat(DISTINCT CONCAT(ej_p.pty_id,'|',ej_p.pty_name,'|',cntunits)) as pty_details"),
DB::raw("group_concat(DISTINCT CONCAT(ej_p.pty_id,'|',ej_p.pty_name)) as pty_details_copy")
)->paginate(10);
When I group_concat the unit_count, only those properties and units are concated where unit exists.
For example the above query returns the following result:
pty_details pty_details_copy
7|I2|2 7|I2, 22|tR ,51|SG APARTMENT,54_||_GA APARTMENTS,
Why properties with units (where unit count=0) are not binding? Where have I gone wrong?
EDIT
Here is the raw query:
select group_concat(DISTINCT CONCAT(p.pty_id,'|',p.pty_name,'|',cntunits)) as pty_details,
group_concat(DISTINCT CONCAT(p.pty_id,'|',p.pty_name)) as pty_details_copy
from users as u
left join properties as p on p.user_id = u.user_id and p.pty_status !=0
left join
(select COALESCE(count(unit_id),0) AS cntunits, pty_id as temp_pty
from property_units as pu3
left join properties as p2 on pu3.unit_pty_id = p2.pty_id
where pu3.unit_status!=0
group by p2.pty_id) as temp on p.pty_id = temp.temp_pty
As Solarflare suggested, i got the required result when I changed the query like this:
$ar = DB::table('users as u')
->leftjoin('properties as p', function($join) {
$join->on('p.user_id', '=', 'u.user_id')->where('p.pty_status', '!=' ,0 );
})
->leftJoin(
DB::raw("
(select COALESCE(count(unit_id),0) AS cntunits, pty_id as temp_pty
from property_units as pu3
left join properties as p2 on pu3.unit_pty_id = p2.pty_id
where pu3.unit_status!=0
group by p2.pty_id) as temp"), 'p.pty_id', '=', 'temp.temp_pty')
->select(
DB::raw("group_concat(DISTINCT CONCAT(ej_p.pty_id,'|',ej_p.pty_name,'|',coalesce(cntunits, 0))) as pty_details"))->paginate(10);
The WHERE from your first join should be part of the ON.

I am new to Laravel and trying to support an existing application that is in Laravel 5. I am trying to convert the following SQL to eloquent structure
SELECT s.id,
CONCAT(u.first_name, ' ', u.last_name) AS user_name,
u.avatar_location AS user_img,
s.employee_photo,
d.name AS department,
seg.name AS segment,
s.survey_title,
s.before_action,
s.before_picture,
s.action,
s.action_date,
s.after_action,
s.after_picture,
s.nominated,
s.awarded,
s.created_at,
s.updated_at,
(SELECT COUNT(1) FROM likes l WHERE l.survey_id = s.id) AS likes,
(SELECT COUNT(1) FROM likes l WHERE l.survey_id = s.id AND l.user_id = 5) AS UserLikes,
(SELECT COUNT(1) FROM comments c WHERE c.survey_id = s.id ) AS comments
FROM surveys s
JOIN departments d
ON s.department = d.id
JOIN segments seg
ON s.segment_id = seg.id
JOIN users u
ON s.user_id = u.id
WHERE s.status = 'Approved'
ORDER BY s.action_date DESC
LIMIT 20 OFFSET 20
I know enough Laravel to know that my basic start would probably be
$surveys = DB::table('surveys')
->join('departments', 'surveys.department', '=', 'departments.id')
->join('segments', 'surveys.segment_id', '=', 'segments.id')
->join('users', 'surveys.user_id', '=', 'users.id')
->where('surveys.status', 'Approved')
->orderBy('surveys.action_date')
->skip(20)-take(20)
->select(...)->get();
However, I am not sure how to do the subqueries. Looking for any suggestions.
Thanks!
For select statements, you can use DB::raw().
$surveys = DB::table('surveys')
->join('departments', 'surveys.department', '=', 'departments.id')
->join('segments', 'surveys.segment_id', '=', 'segments.id')
->join('users', 'surveys.user_id', '=', 'users.id')
->where('surveys.status', 'Approved')
->orderBy('surveys.action_date')
->skip(20)-take(20)
->select([DB::raw('(SELECT COUNT(1) FROM likes l WHERE l.survey_id = s.id) AS likes'),
...
])
->get();
Similarly, select statements would go under the select array. Just so to be clear, the result will be a collection.
I'm trying to sort comments. Each comment could have a parent_id in case it is a replay to another comment.
I need to order all the comments by parent_date and comment_date.
I have created this query:
$union = DB::table("press_comments as c2")
->select("c2.body", "c2.id", 'c2.parent_id', 'c2.created_at as ac', 'p.created_at as ap')
->join('press_comments as p', 'c2.parent_id', '=', 'p.id');
$comments = DB::table('press_comments as c1')
->select("c1.body", "c1.id", 'c1.parent_id', 'c1.created_at as ac', 'c1.created_at as ap')
// ->where("parent_id", "=", 0)
->union($union)
->orderBy("ap","asc")
->orderBy( "ac","asc")
->groupBy('id')
->paginate();
But I got too many lines: the groupBy seems not working on.
In plain mysql it works:
SELECT *
FROM ( SELECT c1.id,
c1.parent_id,
c1.created_at ac,
c1.created_at ap
FROM press_comments c1
UNION
SELECT c2.id,
c2.parent_id,
c2.created_at ac,
p.created_at ap
FROM press_comments c2
JOIN press_comments p
ON c2.parent_id = p.id) c
GROUP BY id
ORDER BY c.ap, c.ac;
What I'm missing in my Laravel query?
I'm having difficulty converting a SQL to the eloquent of laravel, specifically in the part of an inner join, where I make the comparison in a "in" different of the "="
Query:
SELECT
titulo_id as titulo_id,
-- calculate both SUMs, select values for each dependent by what value it matches to
SUM(CASE WHEN ativos_extratos.data_import_id = borders.min_id THEN valor_bruto_atual END) AS valor_min,
SUM(CASE WHEN ativos_extratos.data_import_id = borders.max_id THEN valor_bruto_atual END) AS valor_max,
data_imports.data_import AS created_at,
week(data_imports.data_import) AS weeknumber
FROM
ativos_extratos
INNER JOIN
titulos ON titulo_id = titulos.id
INNER JOIN
representantes ON representante_id = representantes.id
INNER JOIN
data_imports ON data_import_id = data_imports.id
INNER JOIN ( SELECT
MIN(ID) as min_id,
MAX(ID) as max_id
FROM
data_imports
WHERE
data_import BETWEEN '2018-11-01' AND '2018-12-10'
GROUP BY week(data_import)
) borders ON ativos_extratos.data_import_id IN (borders.min_id, borders.max_id)
WHERE
user_id = 1
AND data_imports.data_import BETWEEN '2018-11-01' AND '2018-12-10'
GROUP BY titulos.nome_titulo , weeknumber
Current Eloquent ORM
$rows = AtivosExtrato::select('titulo_id',
DB::raw('SUM(CASE WHEN ativos_extratos.data_import_id = borders.min_id THEN valor_bruto_atual END) AS valor_init'),
DB::raw('SUM(CASE WHEN ativos_extratos.data_import_id = borders.max_id THEN valor_bruto_atual END) AS valor_end'),
'data_imports.data_import AS created_at',
DB::raw('month(data_imports.data_import) AS weeknumber')
)
->join('titulos','titulo_id', '=', 'titulos.id' )
->join('representantes','representante_id', '=', 'representantes.id' )
->join('data_imports','data_import_id', '=', 'data_imports.id' )
->join(DB::raw("
( SELECT
MIN(ID) as min_id,
MAX(ID) as max_id
FROM
data_imports
WHERE
data_import BETWEEN '2018-10-01' AND '2018-12-10'
GROUP BY month(data_import)) borders
"), function ($join){
$join->on('ativos_extratos.data_import_id', 'in', "(borders.min_id, borders.max_id')");
})
->where('user_id', Auth::user()->id)
->whereBetween('data_import', ['2018-01-01', '2018-12-10'])
->groupBy('titulos.nome_titulo')
->groupBy('weeknumber')
->orderBy('data_import')
->orderBy('titulos.nome_titulo')
->get();
The problem is at the time I do the join using the "in", but it does not run as it should, it concatenates "=" and other fields.
You can try to use whereIn,
Here is an example :
$users = DB::table('users')
->whereIn('id', array(1, 2, 3))->get();
Try something like :
$join->whereIn('ativos_extratos.data_import_id', '(borders.min_id, borders.max_id)');
instead of $join->on('ativos_extratos.data_import_id', 'in', "(borders.min_id, borders.max_id')");

I have the following SQL
SELECT C.CUOCODE, C.NAME, COUNT(*) TOTAL_PAYMENT, SUM(P.AMOUNT) TOTAL_AMOUNT
FROM TAX_PAYMENT P
INNER JOIN TAX_CHECKPOINT C ON C.CUOCODE = REGEXP_SUBSTR(P.INVOICEID, 'R....')
WHERE DELETED = 0 AND TO_CHAR(TXTIME,'YYYY-MM-DD') = '2018-04-24'
GROUP BY C.CUOCODE, C.NAME
ORDER BY TOTAL_AMOUNT DESC;
How can i convert to laravel eloquent, i have "Payment" model (table TAX_PAYMENT) with "paymentid" as primary key.
DB::table('TAX_PAYMENT as P')
->select([
'C.CUOCODE',
'C.NAME',
DB::raw('COUNT(*) AS TOTAL_PAYMENT'),
DB::raw('SUM(P.AMOUNT) AS TOTAL_AMOUNT'),
])->Join('TAX_CHECKPOINT C', 'C.CUOCODE', '=', DB::raw('REGEXP_SUBSTR(P.INVOICEID,'R....')'))
->where('DELETED', 0)
->where(DB::raw("TO_CHAR(TXTIME,'YYYY-MM-DD')"), '2018-04-24')
->groupBy('C.CUOCODE')
->groupBy('C.NAME')
->orderBy('TOTAL_AMOUNT', 'desc')
->toSql();
output
SELECT
`C`.`CUOCODE`,
`C`.`NAME`,
COUNT(*) AS TOTAL_PAYMENT,
SUM(P.AMOUNT) AS TOTAL_AMOUNT
FROM
`TAX_PAYMENT` AS `P`
INNER JOIN `TAX_CHECKPOINT C` ON `C`.`CUOCODE` = REGEXP_SUBSTR (P.INVOICEID,"R....")
WHERE
`DELETED` = ?
AND TO_CHAR (TXTIME, 'YYYY-MM-DD') = ?
GROUP BY
`C`.`CUOCODE`,
`C`.`NAME`
ORDER BY
`TOTAL_AMOUNT` DESC
A quick and dirty way would be to use Eloquents select raw like:
$result = DB::select( DB::raw("SELECT C.CUOCODE, C.NAME, COUNT(*)
TOTAL_PAYMENT, SUM(P.AMOUNT) TOTAL_AMOUNT FROM TAX_PAYMENT INNER JOIN
TAX_CHECKPOINT C ON C.CUOCODE
= REGEXP_SUBSTR(P.INVOICEID, 'R....') WHERE DELETED = 0 AND
TO_CHAR(TXTIME,'YYYY-MM-DD') = '2018-04-24' GROUP BY C.CUOCODE,
C.NAME ORDER BY TOTAL_AMOUNT DESC"));
I want to join department d table with department dl table and user u table. I have done this in SQL query.
SELECT distinct(dl.head),
u.user_name,
u.id
from department d
inner join department dl on d.parent_department_string_id=dl.string_id
inner join users u on dl.head=u.user_name
where d.sl_flag=1
I want to do the same in Laravel query. Is it possible to join the same table using join in Laravel?
You can try something like this.
$departmentData = DB::table('department AS d')
->innerJoin('department AS d1', function($join) {
$join->on('d.parent_department_string_id', '=', 'd1.string_id');
})
->innerJoin('users AS u', function($userJoin) {
$userJoin->on('d1.head', '=', 'u.user_name');
})
->where('d.sl_flag', '=', 1)
->select(\DB::raw('distinct(dl.head) AS head'), 'u.user_name', 'u.id')
->get();
