I have a working SQL query.
SELECT stuid,grade,SUM(full_amount) FROM due_payments group by stuid having SUM(full_amount) !=15600
This is working fine in MySQL workbench and phpmyadmin,But i cant seems to get this work in Laravel 5.3
I tried this on Laravel app with no Luck
$someVariable = Input::get(15600);
$results = DB::select( DB::raw("SELECT stuid,grade,SUM(full_amount) FROM due_payments
group by stuid having SUM(full_amount) =:somevariable)", array(
'somevariable' => $someVariable,
)));
Can someone Help me with this.Thank You.
First if all Input::get() doesn't take value as argument but the element name
$someVariable = Input::get(15600);
You can just use $someVariable = 15600;
Then use Query Builder rather than Raw SQL query
$results = DB::table('due_payments')
->select(array('stuid', 'grade', DB::raw('SUM(full_amount)')))
->groupBy('stuid')
->havingRaw('SUM(full_amount) != '.$someVariable)
->get();
Use query builder.
$results = DB::table('due_payments')
->select('stuid', 'grade',DB::raw('SUM(full_amount)'))
->groupBy('stuid')
->havingRaw('SUM(full_amount) != 15600')
->get();

I am trying to write a MySQL select query using Laravel's Database Query Builder
I have this mysql query:
SELECT * FROM `tweets` WHERE `user_id` = 1 OR `user_id` in (SELECT `follows_id` from `follows` where `user_id` = 1)
I am trying to write it for Laravel
$users = DB::table('tweets')
->where('user_id', '=', 1)
how can this be done?
You can do something like this even though it looks ugly.
$tweets = DB::table('tweets')
->where('user_id', 1)
->orWhereIn('user_id', DB::table('follows')->select('follows_id')->where('user_id', 1)->pluck('follows_id'))
->get();
I would suggest a SQL rewrite as OR and IN(SELECT ...) tends to optimize badly.
The SQL result might be wrong as you didn't provide example data and expected result see Why should I provide a Minimal Reproducible Example for a very simple SQL query? for providing those.
SELECT
tweets.*
FROM
tweets
WHERE
tweets.user_id = 1
UNION ALL
SELECT
tweets.*
FROM
tweets
INNER JOIN
follows ON tweets.user_id = follows.follows_id
WHERE
follows.user_id = 1
I believe the following Laraval code should do that. But not sure as i didn't program in Laravel for some time now.
<?php
$first = DB::table('tweets')
->select('tweets.*')
->where('user_id', '=', 1);
$second = DB::table('tweets')
->select('tweets.*')
->join('follows', 'tweets.user_id', '=', 'follows.follows_id')
->where('follows.user_id ', '=', 1)
->union($first)
->get();
?>
I'm using Laravel and have a very specific query that I don't know how to implement with query builder.
The query:
SET #c_num=0;
SELECT *, #c_num:=#c_num+1 AS 'COUNT'
FROM table_name
WHERE USERID = 2
ORDER BY id
Thank you
You should be able to do something like:
DB::statement(DB::raw('SET #c_num = 0'));
$result = DB::table('table_name')
->selectRaw("*, #c_num:=#c_num+1 AS 'COUNT'")
->where('userid', 2)
->orderBy('id')
->get();
$data = DB::table('table_name')
->where('userid',2)
->select('table_name.*',DB::raw('(#c_num:=#c_num+1) Count')
->orderBy('id')
->get();
You can try the following
DB::table('table_name')
->selectRaw("*, #c_num:=IF(#c_num, #c_num+1, 1) as 'COUNT'")
->where('user_id', 2)
->orderBy('id');
Hi I have a query in my laravel project which should retrieve dates between ranges. My query is:
$dateFrom = date("Y-m-d", strtotime($request->dateFrom));
$dateTo = date("Y-m-d", strtotime($request->dateTo));
$posts = DB::table('posts')->join('categories','posts.category_id','=','categories.id')->
join('users','posts.user_id','=','users.id')
->select('posts.id','posts.topic','categories.category_name','posts.created_at','users.name')
->whereBetween('posts.created_at',[$dateFrom,$dateTo])
->get();
I'd like to use DATE mysql_function on column posts.created_at but I don't know how could I do it. Below query dosen't work:
$dateFrom = date("Y-m-d", strtotime($request->dateFrom));
$dateTo = date("Y-m-d", strtotime($request->dateTo));
$posts = DB::table('posts')->join('categories','posts.category_id','=','categories.id')->
join('users','posts.user_id','=','users.id')
->select('posts.id','posts.topic','categories.category_name','posts.created_at','users.name')
->whereBetween('DATE(posts.created_at)',[$dateFrom,$dateTo])
->get();
I would be greatful for help. Best regards ;)
change ->whereBetween('DATE(posts.created_at)'
to ->whereBetween(DB::raw('DATE(posts.created_at)'))
if you want to add some raw expression in a query you can use DB::row method as mentioned in laravel documentation
Try using Carbon like this:
use Carbon\Carbon;
...
$dateFrom = Carbon::parse($request->dateFrom);
$dateTo = Carbon::parse($request->dateTo);
$posts = DB::table('posts')
->join('categories','posts.category_id','=','categories.id')
->join('users','posts.user_id','=','users.id')
->select('posts.id','posts.topic','categories.category_name','posts.created_at','users.name')
->whereBetween('posts.created_at',[$dateFrom,$dateTo])
->get();
I have the following sql query
SELECT * FROM exams WHERE exams.id NOT IN (SELECT examId FROM testresults)
how can I convert it into Laravel query builder format?
Thanks.
You can use whereNotIn with a closure:
$result = DB::table('exams')->whereNotIn('id', function($q){
$q->select('examId')->from('testresults');
})->get();
with Eloquent :
$result = Exams::whereNotIn('id', function($q){
$q->select('examId')->from('testresults');
})->get();
I have tried to make codeigniter query from mysql query
my mysql query is:
select *
from class_routine
where
semester='$semester'
and day='$day'
and time_schedule='$time_schedule'
and (batch='$batch' or section='$section' or teacher='$teacher' or room='$room');
for above query what will be the codeigniter query ?
I will use this query in model.
First, you should consider looking at the Documentation before asking any question, then specify what you've looked at and what you did try, posting your code.
Anyways, try this and let me know:
$this->db->where(array('semester' => $semester, 'day' => $day, 'time_schedule' => $time_scehdule));
$this->db->where("batch = $batch OR section = $section OR teacher = $teacher OR room = $room", NULL, FALSE);
$result = $this->db->get('class_routine')->result();
When in doubt is perfectly safe to use a normal query:
$result = $this->db->query("SELECT * FROM ....")->result();
