I have the following query. Could you please tell me how to implement it in codeigniter.
SELECT mnu_name,mnu_desc,mnu_type FROM central_web_auth_mnu
WHERE mnu_name NOT IN(
SELECT mnu_name FROM central_web_auth_grp_mnu WHERE gr_id='.$grp.'
) ORDER BY mnu_desc;
Thank You.
$this->db->select('mnu_name, mnu_desc, mnu_type')->where('`mnu_name` NOT IN (SELECT `mnu_name` FROM `central_web_auth_grp_mnu` WHERE idgr_id= $grp)', NULL, FALSE)->order_by('mnu_desc', 'desc')->get('central_web_auth_mnu');
set false as third parameter so that escaping will skip:
CI active db library does support array params in where_in() or where_not_in() methods, so you can use where() method and pass condition as string, try this query
$this->db->select('mnu_name, mnu_desc, mnu_type')
->where('mnu_name NOT IN(SELECT mnu_name FROM central_web_auth_grp_mnu WHERE gr_id='.$grp.')')
->order_by('mnu_desc', 'desc')
->get('central_web_auth_mnu')
You can simply use codeigniter's Active Record library to achieve this (thanks Girish)
$this->db->select('mnu_name, mnu_desc, mnu_type')
->where('mnu_name NOT IN(SELECT mnu_name FROM central_web_auth_grp_mnu WHERE gr_id='.$grp.')')
->order_by('mnu_desc', 'desc');
$query = $this->db->get();
$num_rows = $query->num_rows();

I am trying to use laravel query builder like:-
$users = DB::table('baid_collection')
->select(DB::raw('sum(total) as total_collect,collection_limit_c'))
->join('users_cstm', 'baid_collections.assigned_user_id', '=', 'users_cstm.id_c')
->where(DB::raw("assigned_user_id = '$userId' and DATE(date_entered)=CURDATE()"))
->groupBy('assigned_user_id')
->get();
This query should be like
select sum(total) as total_collect,collection_limit_c from `baid_collections` inner join `users_cstm` on `baid_collections`.`assigned_user_id` = `users_cstm`.`id_c` where assigned_user_id = '15426608-3ea5-f299-7a80-601bd06be2d9' and DATE(date_entered)=CURDATE() group by `assigned_user_id`
But last run query showing me
select sum(total) as total_collect,collection_limit_c from `baid_collection` inner join `users_cstm` on `baid_collections`.`assigned_user_id` = `users_cstm`.`id_c` where assigned_user_id = '15426608-3ea5-f299-7a80-601bd06be2d9' and DATE(date_entered)=CURDATE() is null group by `assigned_user_id`
In query is null giving problem i dont want is null in query
Use whereRaw instead of where like
$users = DB::table('baid_collections')
->select(DB::raw('sum(total) as total_collect,collection_limit_c'))
->join('users_cstm', 'baid_collections.assigned_user_id', '=', 'users_cstm.id_c')
->whereRaw("assigned_user_id = '{$userId}' and DATE(date_entered)=CURDATE()")
->groupBy('assigned_user_id')
->get();
It's creating a problem due to where needs atleast two parameters and you are just passing one parameter
Check this if it helps, write whereDate instead of add date in raw query.
if you are not using Carbon, you can also use php date("Y-m-d"), method to get date
DB::table('baid_collection')
->select(DB::raw('sum(total) as total_collect,collection_limit_c'))
->join('users_cstm', 'baid_collections.assigned_user_id', '=', 'users_cstm.id_c')
->where(DB::raw("assigned_user_id = '$userId'"))
->whereDate("date_entered", "=", Carbon::now()->toDateString())
->groupBy('assigned_user_id')->get();
You can try this
$users = DB::table('baid_collection')
->select(DB::raw('sum(total) as total_collect,collection_limit_c'))
->join('users_cstm', 'baid_collections.assigned_user_id', '=', 'users_cstm.id_c')
->where(DB::raw("assigned_user_id = '$userId' and DATE(date_entered) = '".date('Y-m-d')."'"))
->groupBy('assigned_user_id')
->get();
i want to get contact id who was send chat or was i send chat to him
with native query i can get result but when i implement in laravel its going difficult
this my native query
select * from `users` where `users`.`id` in (
select `to` from messages where `from` = 2 group by `to`
union
select `from` from messages where `to` = 2 group by `from`
)
what i find difficult is how union after group by or group by after union with make same column number, i using merge but the result is wrong
this what i have try in laravel
$to = Message::select('to')->where('from',auth()->id())->groupBy('to')->get();
$from = Message::select('from')->where('to',auth()->id())->groupBy('from')->get();
$tofrom = $to->merge($from);
dd($tofrom);
please if any body can help
Unions are described in the documentation. To achieve your specific requirements you can do:
$final = User::whereIn('id', function ($query) {
$from = Message::select('from')->where('from',auth()->id())->groupBy('from');
$query->from('messages')->where('to',auth()->id())->groupBy('to')->union($from);
})->get();
Disclaimer: I have not actually tested this but I think it should work.
merge() is the method of collection. Not the Eloquent Builder or Query Builder.
However, It think you want to find user.id in the array.
You can convert the collection to array:
$to = Message::where('from',auth()->id())->groupBy('to')->pluck('to');
$from = Message::where('to',auth()->id())->groupBy('from')->pluck('from');
$tofrom = $to->merge($from)->toarray();
User::whereIn('id', $tofrom)->get();
oh finally i got the answer this is code
$contacts = User::select('users.id','users.name','users.email','users.profile_image')
->join('messages',function($join){
$join->on('users.id','messages.from');
$join->orOn('users.id','messages.to');
})
->where(function($query){
$query->where('messages.from',auth()->id())->orWhere('messages.to',auth()->id());
})
->groupBy('users.id','users.name','users.email','users.profile_image')
->get();
I want to convert this code in laravel.
SELECT MAX(date_start) AS DateStart,MIN(date_end) AS DateEnd FROM DBTest
And I try this code
$data = DB::table('DBTest')
->select(max('date_start'), min('date_end')))
->get();
Return Error: max(): When only one parameter is given, it must be an array
I am using laravel 5.2, and SQLyog as database
I am confuse in syntax please help me
You can't use functions in select statement, but you can use raw SQL :
$data = DB::table('DBTest')
->select(\DB::raw('MIN(date_start) AS DateStart, MAX(date_end) AS DateEnd'));
->get();
You can do it like this:
For the max start date:
max = DB::table('DBTest')->select('date_start')->orderBy('date_start', 'desc')->first();
For min end date:
min = DB::table('DBTest')->select('date_end')->orderBy('date_end', 'asc')->first();
You have to use something called selectRaw method in Laravel in order to achieve this result. Chaining method like ->max('columnA')->min('columnB') will not work. So, here is the solution:
$data = DB::table('DBTest')
->selectRaw('MAX(date_start) AS DateStart, MIN(date_end) AS DateEnd')->get();
Try MIN() and MAX() functions in the sql query.
$data = DB::table('DBTest')
->select(\DB::raw('MIN(date_start) AS startDate, MAX(date_end) AS endDate'));
->get();
can I convert this query
"SELECT * FROM (SELECT * FROM blog_post ORDER BY data DESC) blog_post GROUP BY blog_id LIMIT 2"
into a Yii2 active record query?
Thx
Ms
Yes, you can do this.
Yii2 gave us a wonderful library support.
You can form custom sql query and pass this query in findBySql() like:
$sql = "Some query/nested query";
$result = ModelClass::findBySql($sql);
Visit Yii official documentation.
BlogPost::find()
->orderBy('data DESC')
->groupBy('blog_id')
->limit(2)
->all();
I suppose you can do in this way :
Ⅰ:create a subQuery where you select from.
$blogPostQuery = BlogPostModel::find()->orderBy(['data' => SORT_DESC]);
Ⅱ:Get activeRecord results. The from params is an exist Query.
$models = (new yii\db\Query)
->from(['blog_post ' => $blogPostQuery])
->groupBy(['blog_id'])
->limit(2)
->all();
ps:
see yii\db\query->from()-detail in Yii Api;
(public $this from ( $tables )) $tables can be either a string (e.g. 'user') or an array (e.g. ['user', 'profile']) specifying one or several table names··· or a sub-query or DB expression
Have a try!I hope it`s useful for you:))
I'm trying to group my entity by a field (year) and do a count of it.
Code:
public function countYear()
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb->select('b.year, COUNT(b.id)')
->from('\My\Entity\Album', 'b')
->where('b.year IS NOT NULL')
->addOrderBy('sclr1', 'DESC')
->addGroupBy('b.year');
$query = $qb->getQuery();
die($query->getSQL());
$result = $query->execute();
//die(print_r($result));
return $result;
}
I can't seem to say COUNT(b.id) AS count as it gives an error, and
I do not know what to use as the addOrderby(???, 'DESC') value?
There are many bugs and workarounds required to achieve order by expressions as of v2.3.0 or below:
The order by clause does not support expressions, but you can add a field with the expression to the select and order by it. So it's worth repeating that Tjorriemorrie's own solution actually works:
$qb->select('b.year, COUNT(b.id) AS mycount')
->from('\My\Entity\Album', 'b')
->where('b.year IS NOT NULL')
->orderBy('mycount', 'DESC')
->groupBy('b.year');
Doctrine chokes on equality (e.g. =, LIKE, IS NULL) in the select expression. For those cases the only solution I have found is to use a subselect or self-join:
$qb->select('b, (SELECT count(t.id) FROM \My\Entity\Album AS t '.
'WHERE t.id=b.id AND b.title LIKE :search) AS isTitleMatch')
->from('\My\Entity\Album', 'b')
->where('b.title LIKE :search')
->andWhere('b.description LIKE :search')
->orderBy('isTitleMatch', 'DESC');
To suppress the additional field from the result, you can declare it AS HIDDEN. This way you can use it in the order by without having it in the result.
$qb->select('b.year, COUNT(b.id) AS HIDDEN mycount')
->from('\My\Entity\Album', 'b')
->where('b.year IS NOT NULL')
->orderBy('mycount', 'DESC')
->groupBy('b.year');
what is the error you get when using COUNT(b.id) AS count? it might be because count is a reserved word. try COUNT(b.id) AS idCount, or similar.
alternatively, try $qb->addOrderby('COUNT(b.id)', 'DESC');.
what is your database system (mysql, postgresql, ...)?
If you want your Repository method to return an Entity you cannot use ->select(), but you can use ->addSelect() with a hidden select.
$qb = $this->createQueryBuilder('q')
->addSelect('COUNT(q.id) AS HIDDEN counter')
->orderBy('counter');
$result = $qb->getQuery()->getResult();
$result will be an entity class object.
Please try this code for ci 2 + doctrine 2
$where = " ";
$order_by = " ";
$row = $this->doctrine->em->createQuery("select a from company_group\models\Post a "
.$where." ".$order_by."")
->setMaxResults($data['limit'])
->setFirstResult($data['offset'])
->getResult();`
