Mysql Query :
SELECT SUM(`Item_qty`), `bill_id`,`Item_name`,`table_id`,`Item_price`
FROM tbl_billmenu
WHERE `table_id` = 30
GROUP BY `Item_name`
How should I've to code/implement this above query in codeigniter module ? please help
This is how you do it:
$this->db->select(bill_id,Item_name,table_id,Item_price,sum(Item_qty) as quantity);
$this->db->where('table_id', 30);
$query = $this->db->get('tbl_billmenu');

SELECT *
FROM `digital_useraccess`
left join digital_publisher ON
access_publisher = pub_auto
left join digital_issue ON
issue_publisher = pub_auto
WHERE 1
without using laravel DB class method
Try this as reference
ModelName::where(conditions)
->leftjoin('digital_publisher','access_publisher','pub_auto')
->leftjoin('digital_issue','issue_publisher ','pub_auto')
->select('column_1','column_2',...)->get();
This might help :
::query()->where('<cplumn>' , '<operator>' ,
'<value>')->leftJoin('digital_publisher', 'access_publisher',
'=','pub_auto')->leftJoin('digital_issue', 'issue_publisher', '=',
'pub_auto')->select('<columns>')->get();/find();/first();
I would like to reproduce following mySQL query using Laravel query builder:
*SELECT SUM(scores) FROM (SELECT scores FROM player_games WHERE player_id = 1 ORDER BY id DESC LIMIT 2) scores
Any suggestions?
Here the solution:
$sub = playerGame::where('player_id',1)->where('scores','>',0)->limit(2)->orderBy('id','desc');
$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
->mergeBindings($sub->getQuery())
->sum('scores');
return $count;
Use fromSub():
$sub = playerGame::select('scores')
->where('player_id', 1)
->where('scores', '>', 0)
->limit(2)
->orderBy('id','desc');
$sum = DB::query()->fromSub($sub, 'scores')->sum('scores');
$responce= DB::table('player_games')->where('player_id',1)->sum('amount');
dd(collect($responce)->sortByDesc('id')->take(2));
please cheack this one.....i try it's work....and add use DB;in the top of controller....
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:))
<?php
$this->db->select('*');
$this->db->from('venue');
$this->db->join('venue_type vt1', 'vt1.venue_type_id = venue.venue_type_id1');
$this->db->join('venue_subtype vst1', 'vst1.venue_subtype_id = venue.venue_subtype_id1');
$this->db->join('venue_type vt2', 'vt2.venue_type_id = venue.venue_type_id2');
$this->db->join('venue_subtype vst2', 'vst2.venue_subtype_id = venue.venue_subtype_id2');
$this->db->join('venue_type vt3', 'vt3.venue_type_id = venue.venue_type_id3');
$this->db->join('venue_subtype vst3', 'vst3.venue_subtype_id = venue.venue_subtype_id3');
$this->db->where('venue_id',$id);
$query = $this->db->get();
i have venue table it has more then 1 field relation b/w venue_type. When i try to give first relation
<?php
$this->db->join('venue_type vt1', 'vt1.venue_type_id = venue.venue_type_id1');
$this->db->join('venue_subtype vst1', 'vst1.venue_subtype_id = venue.venue_subtype_id1');
its working fine , but i try to access whole its not working.
Please Help me. (It may simple but i stuck)

You need to use alias for multiple joins.
SELECT st_id, table1.us_login, table2.us_login
FROM (stream)
LEFT JOIN users AS table1 ON table1.us_id = stream.st_id_user_from
LEFT JOIN users AS table2 ON table2.us_id = stream.st_id_user_to
see the link: http://codeigniter.com/forums/viewthread/151176/
There's no $this->db->from function in Codeigniter. Use instead $this->db->select('venue.*')
I have this:
$this->db->select('(select var_value from contents where table = "products" and table_id = products.id and var_name = "image" and name = "images" order by id asc limit 1) as main_picture');
$this->db->where('category_id', $cat)->from('products')->limit($limit, $start)->get();
The problem is that codeigniter is removing the "limit 1" inside the subquery...
Any advice?
Thx!
You can not use LIMIT inside $this->db->select(); method
Please refer to Active Record documentation
$this->db->get();
$this->db->get_where();
Are the only methods that allow the use of LIMIT
