I want to count a field name 'leave_policy' depending on the name of 'leave_policy' and I am using joins to do it. My database is like this
https://imgur.com/a/gR3Dw
and I want to show count in applied section. For example if I want to count all "Urgent Leaves" and "Paternal Leaves" seperately I have applied till now. https://imgur.com/a/dvjuX
$join = DB::table('leaves_policy')
->join('leaves_policies', 'leaves_policy.leave_policy', '=', 'leaves_policies.title')
->join('leaves_requests', 'leaves_policy.requested_by' , '=', 'leaves_requests.requested_by')
->select('leaves_policy.*', 'leaves_policies.title', 'leaves_policies.total_no_of_leaves_allowed_per_year',
'leaves_policies.no_of_months_leaves_valid', 'leaves_policies.max_leaves_per_month', 'leaves_policies.max_con_leaves_per_month',
'leaves_requests.leave_status', DB::raw('COUNT(leaves_policy.leave_policy) as count'))
->groupBy('id')
->get();
For example,
I have a table Leave_table. leave_policy and purpose are the fields.
I am displaying the leave count based on the leave_policy column. i have used the below query to get the count.
select leave_policy,count(leave_policy) from leave_table group by leave_policy

$tren = DB::table('suka')
->join('buku', 'buku.ISBN', '=', 'suka.ISBN')
->join('user', 'user.id_user', '=', 'suka.id_user')
->raw('count(*) as total')
->groupBy('suka.ISBN')
->orderBy('maximum')
->LIMIT(2)
->get();
I want to group a join table by ISBN and then find the maximum count of them and take 2 of the most.
here is the error message
Call to undefined method Illuminate\Database\Query\Expression::groupBy()
There is more than one ISBN column in the result set (because it exists in multiple tables). You should specify which table's ISBN column you want to group by in your group by call.
Also, try calling selectRaw instead of raw:
->selectRaw('count(*) as total')
You can read more about raw queries in this documentation.
I want to have in my model, instead of the complete set of entries of the models contained by another one, just the quantity of them. I could do this by adding the "size" field to the resultset, but I'd like to do this in the query, as I want to paginate and order the results dinamically. I am using this code, but for some reason, if the first count is different from zero, both count fields have the same value, which is the value of the second count field.
$query = $this->Users->find('all')
->contain(['Likes','Favs']);
$query
->select(['like_count' => $query->func()->count('Likes.id')])
->leftJoinWith('Likes')
->group(['Users.id'])
->autoFields(true);
$query
->select(['fav_count' => $query->func()->count('Favs.id')])
->leftJoinWith('Favs')
->group(['Users.id'])
->autoFields(true);
$this->paginate['sortWhitelist'] = [
'name',
'email',
'last_login',
'fav_count',
'like_count',
];
I would like to know why this happens and if there is any other way to do what I attempt, which would be to have ('name', email, 'last_login', quantity of entries in Likes with the user's id, quantity of entries in Favs with the user's id). I have tried using join() to do the left join, but I haven't been able to obtain the result I want.
If you have multiple joins, then you need to count with DISTINCT, eg:
COUNT(DISTINCT Likes.id)
This is because your result will contain Likes * Favs number of rows, as for every joined like, all favs will be joined, ie for 2 likes and 10 favs you'd end up with 20 rows in total. A regular COUNT() would include every single one of those rows.
Also note that you don't need to repeat all that grouping, etc stuff, and you can use a callable for select() to avoid breaking up the builder.
$query = $this->Users
->find('all')
->select(function (\Cake\ORM\Query $query) {
return [
'like_count' => $query->func()->count(
$query->func()->distinct(['Likes.id' => 'identifier'])
),
'fav_count' => $query->func()->count(
$query->func()->distinct(['Favs.id' => 'identifier'])
),
];
})
->autoFields(true)
->contain(['Likes', 'Favs'])
->leftJoinWith('Likes')
->leftJoinWith('Favs')
->group(['Users.id']);
Using the functions builder to generate the DISTINCT is a workaround, as there is no API yet that would allow to specifically generate a keyword. The result will be something like DISTINCT(Likes.id), but it will work fine, the parentheses will be interpreted as part of the expression after the keyword, not as part of a function call.
I want to get cumulative salary monthly(the table name is cumulative_salary) from another table(the table name is salary), then update the data. I just can 'get()' the data but i can't update. I'm so confusing and i don't know the correct syntax. So, this is my code.
$data = DB::table('salary')
->where('employee_id', $employee_id)
->leftJoin('employees', 'salary.employee_id', '=', 'employees.id')
->select(DB::raw('SUM(salary_overtime) as `salary`'),
DB::raw('YEAR(overtime_date) year, MONTH(overtime_date) month'))
->groupby('month','year')
->get();
I have written the following function to display a table consisting of
recipe name, description, cusine , ........ ..., ingredients AND LIKES.
Everything works fine but the likes column doesnot show the no. of likes bu instead sows the no. of ingredients of the recipe
public function rec(){
$ing = inglist::all();
$rcusine=recipecusine::all();
$rtype=recipetype::all();
$rec = DB::table('recipe_list')
->select('recipe_list.recipe_id','recipe_list.Recipe_name',
'recipe_list.Recipe_desc','recipe_list.Recipe_duration',
DB::raw('group_concat(ing_list.Ing_name separator ",") as recipe_ingredients'),
'recipe_cusine.Cusine_name', 'recipe_type.Recipe_type_name','recipe_list.image',
DB::raw('count(likerecipes.likecount) as likes'))
->join('recipe_inglist', 'recipe_list.recipe_id','=','recipe_inglist.Recipe_id')
->join('ing_list', 'recipe_inglist.Ing_id','=','ing_list.ing_id')
->join('recipe_cusine', 'recipe_list.Recipe_cusine_id','=','recipe_cusine.cusine_id')
->join('recipe_type', 'recipe_list.Recipe_type_id','=','recipe_type.Recipe_typeID')
->join( 'likerecipes', 'recipe_list.recipe_id', '=', 'likerecipes.recipe_id')
->where('recipe_list.recipe_id','>=','1')
->groupBy('recipe_list.recipe_id', 'recipe_list.recipe_name','recipe_list.recipe_desc','recipe_list.recipe_duration', 'recipe_cusine.Cusine_name','recipe_type.Recipe_type_name','recipe_list.image' )->get() ;
/* var_dump($rec);
die();*/
return view('recipe', ['ingredients'=>$ing, 'cusine'=>$rcusine, 'type'=>$rtype,'recipe'=>$rec]);
}
the output i get is
and this is my likerecipes table
can anyone help me where i am wrong.
Because of the joins, your data is duplicated through the records. Since the likerecipes table seems to store like votes casted one by one identified by an id field uniquely, I would count the distinct likerecipes.id values per group:
'count(distinct likerecipes.id) as likes'
I would also introduce the distinct to the group_concat() to make sure that multiple like votes do not make the same ingridients appear multiple times:
'group_concat(distinct ing_list.Ing_name separator ",") as recipe_ingredients'
Here is my Database structure:
Also - there is a table users and reciever_id references that table id.
I use that query to get count of each type of notifications as well as data for that type of notifications from notification_types table.
Notification::
select('notification_types.*', DB::raw('count(*) as total'))
->join('notification_types', 'notifications.type_id', '=', 'notification_types.id')
->groupBy('notifications.type_id')
->get()
What I need - is to set constraint on reciever_id, I just don't get - where should I put the where clause?
Just chain the where method anywhere before get, since your condition will be applied on the notifications table:
Notification::select('notification_types.*', DB::raw('count(*) as total'))
->join('notification_types', 'notifications.type_id', '=', 'notification_types.id')
->where('reciever_id', $receiverId)
->groupBy('type_id')
->get();
Also, there's no need with this query to group by notifications.type_id, type_id will do, because there are no ambiguities created here because there are no other columns named type_id.
