I am trying to make the following query in laravel:
SELECT a.name AS subname, a.area_id, b.name, u. id, u.lawyer_id,u.active_search,
FROM subarea a
LEFT JOIN user_subarea u ON u.subarea_id = a.id
AND u.user_id = ?
LEFT JOIN branch b ON a.area_id = b.id
The idea is to obtain the subareas and see if the search is activated by the user.
The user_subarea table might have a record that matches the id of the subarea table where the active_search is equal to 0 or 1. If it doesn't exist I would like the query to return null.
While I was able to achieve this in raw SQL when I try the same with eloquent in Laravel I am not returning any value. I have done the following:
$query = DB::table('subarea')
->join('user_subarea', function($join)
{
$value = \Auth::user()->id;
$join->on( 'subarea.id', '=', 'user_subarea.subarea_id')->where('user_subarea.user_id', '=',$value);
})
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('branch.name', 'subarea.name as subarea', 'user_subarea.active_search_lawyer', 'user_subarea.id' )
->get();
Any help will be much appreciated.
I found by myself the answer it was just to add a lefjoin in the first join. It is not in the laravel docs but works too.
$query = DB::table('subarea')
->lefjoin('user_subarea', function($join)
{
$value = \Auth::user()->id;
$join->on( 'subarea.id', '=', 'user_subarea.subarea_id')->where('user_subarea.user_id', '=',$value);
})
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('branch.name', 'subarea.name as subarea', 'user_subarea.active_search_lawyer', 'user_subarea.id' )
->get();
Try this one, If you get a problem, please comment.
$value = \Auth::user()->id;
$query = DB::table('subarea')
->where('user_subarea.user_id', '=',$value)
->leftJoin('user_subarea', 'subarea.id', '=', 'user_subarea.subarea_id')
->leftJoin('branch', 'subarea.area_id', '=', 'branch.id')
->select('subarea.name AS subname','subarea.area_id', 'branch.name', 'user_subarea.id','user_subarea.lawyer_id','user_subarea.active_search')
->get();

I am trying to turn my raw sql into laravel query builder and I encounter difficulty on how to join multiple tables using with many attributes match.
In this case, I want to join the table jr_h and jr_d with three attributes match (book,p_seq and staff_code) rather than one (book).
Raw sql:
$sql = "select from_time,to_time,t.staff_code,s.name_t as staff_name,t.book,t.p_code,t.p_seq,p.hrs1,s.img_file,
t.hrs_work,p.sharing_cnt as hrs_work, t.hrs_ot as hrs_ot from jr_d as t
inner join jr_h as p on(t.book=p.book and t.p_seq=p.p_seq and t.staff_code=p.staff_code)
inner join astaff as s on(t.staff_code=s.staff_code) ";
Laravel query builder:
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();
and also want to know if there is a way to make the query faster since it has a lot of data in the tables.
Laravel joins with multiple conditions:
$results = DB::table('jr_d')
->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('jr_h as p', function($query){
$query->on('t.book','=', p.book');
$query->on('t.p_seq','=', 'p.p_seq');
$query->on('t.staff_code', '=', 'p.staff_code');
})
->where('jr_d.ref_group','=','E')
->get();
`
Try this:
// ...
->join('jr_h p', function($join) {
$join->on('t.book', '=', 'p.book');
$join->on('t.p_seq', '=', 'p.p_seq');
// ... more conditions
});
Try this.
$jr_d = DB::table('jr_d')
->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
->select('*','astaff.name_t as staff_name')
->where('jr_d.ref_group','=','E')
->get();
i am having this query with me which needs to be written in the eloquent form on internet not able to find exact solution for my problem.
SELECT
query_id, t1.time, result, platform_id
FROM
query_logs t1
WHERE
t1.time = (SELECT
MAX(time)
FROM
query_logs t2
WHERE
t1.query_id = t2.query_id);
i tried writing it as below i used query_Logs as model to my controller:
$bmdata = Query_Logs::select('query_id', 'time','result','platform_id')
->where('time', function($q){
$q->from('query_logs')
->selectRaw('max(time)')
->where('query_id', '=', 'query_id')
})
->get();
Can you guys help me with the same.
Use this:
$bmdata = Query_Logs::select('query_id', 'time', 'result', 'platform_id')
->where('time', function($q) {
$q->from('query_logs as t2')
->selectRaw('max(time)')
->whereColumn('t2.query_id', '=', 'query_logs.query_id');
})->get();
I am trying to do an eloquent query where it joins on a table where column a = x OR column b = x; and I cannot get it to work. So I am hoping that someone can help.
Here is my query:
$candidates = HrCandidate::where('people_id', '<>', 'NULL')
->with('contact')
->join(
'people',
->where('id','people_id')
->orWhere('alternate_id','people_id')
)
->get();
I am trying to join with the people table but where people_id = 1 or the alternate_id column. So I am hoping someone can help with this.
To get started, pass a Closure as the second argument into the join method. The Closure will receive a JoinClause object which allows you to specify constraints on the join clause:
$candidates = HrCandidate::join('people', function ($join) {
$join
->on('people.id', '=', 'candidates.people_id')
->orOn('people.alternate_id', '=', 'candidates.people_id');
})
->where('people_id', '<>', 'NULL')
->get();
I have two tables - the first one is called 'users' and the second one is called 'buy_courses'.
I am trying to select all users those user_name is not in buy_courses. I tried something like -
$users = DB::table('users')
->rightjoin('buy_courses', 'users.user_name', '=', 'buy_courses.user_name')
->get();
It returns all users, whose user_name is in 'buy_courses', when I am using '<>', then I'm getting all users. What should be the right query?
DB::table("users")->select('*')->whereNotIn('user_name',function($query) {
$query->select('user_name')->from('buy_courses');
})->get();
just join actually is inner join in Laravel so actually maybe also you can try:
DB::table('users')
->join('buy_courses', 'users.user_name', '=', 'buy_courses.user_name')
->get();
Try it using Eloquent:
$courseUserNames = BuyCourses::pluck('user_name')->all();
$users = User::whereNotIn('user_name', $courseUserNames)->select(...)->get();
Or if you prefer using DB query:
$courseUserNames = DB::table('buy_courses')->pluck('user_name')->all();
$users = DB::table('users')->whereNotIn('user_name', $courseUserNames)->select(...)->get();
just replace = with != , use function join
$users = DB::table('users')
->join(
'buy_courses',
function ($join)
{$join->on('users.user_name', '!=', 'buy_courses.user_name');}
)
->get();
You can use SQL's 'NOT IN'.
Example:
mysqli_query($con, "SELECT * FROM users WHERE user_name NOT IN (SELECT user_name FROM buy_courses)");
I have the following MySQL query:
SELECT
*
FROM
news_posts
WHERE
user_id = ?
AND id NOT IN (SELECT
post_id
FROM
user_read
WHERE
user_id = ?)
I want to make it more "eloquent". I've tried the following, but its (obviously) not working:
NewsPost::where('user_id', Auth::id())
->whereNotIn(function ($query) {
$query->DB::table('user_read')
->select('post_id')
->where('user_id', Auth::id());
})->get();
I'm assuming the 'where' method is executing a simple SQL query on 'new_posts' table. Can you try to rewrite this query and let mysql do the filtering for new posts? (search for LEFT OUTER JOIN on mysql)
SELECT *
FROM news_posts a
JOIN user_read b
ON a.id = b.post_id
WHERE a.user_id = ?
AND b.post_id IS NULL;
Thanks for all the replies! Got it working with the following tweaks:
NewsPost::where('user_id', Auth::id())
->whereNotIn('id', function ($query) {
$query->select('post_id')
->from('user_read')
->where('user_id', Auth::id());
})
->get();
