I'm working on querying my mysql database via doctrine in a symfony2 app. I have a basic table set up that includes an id number ('id'), name ('name'), and a last column for if the person has been contacted ('contacted'), depicted with 0 or 1. I can query and get the number of total inquiries (depicted in the controller with $inquiryCountTotal just fine.
I'm struggling to count the rows that have been contacted. I figure I can either COUNT the rows with a value of 1 in the contacted column or I could just SUM all the rows in the contacted column.
For some reason it seems to be summing the ids, as I have 8 ids and it's spitting a number of 36.
Where am I going wrong? Thanks in advance!
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$entities = $em->getRepository('EABundle:Inquiry')
->findBy(array(), array('id'=>'DESC'));
$inquiryCountTotal = $em->createQuery("
SELECT count(id)
FROM EABundle:Inquiry id
")->getSingleScalarResult();
//This is the part I'm struggling with...
$inquiryCount = $em->createQuery("
SELECT sum(contacted)
FROM EABundle:Inquiry contacted
")->getSingleScalarResult();
return $this->render('EABundle:Inquiry:index.html.twig', array(
'entities' => $entities,
'inquiryCount' => $inquiryCount,
'inquiryCountTotal' => $inquiryCountTotal
));
}
Doctrine is interpreting the alias as the id of the entity.
Try this:
$inquiryCount = $em->createQuery("
SELECT sum(i.contacted)
FROM EABundle:Inquiry i
")->getSingleScalarResult();

I have 2 databases(one in mySql and the other one in MongoDB) in my project and I need to perform a query like this
public function getPosts() {
$user = Auth::user();
$follow = DB::connection("mongodb")
->collection("followers")
->where("user_id", $user->id)->get();
/*$res = DB::select("
SELECT *
FROM posts
WHERE user_id = ? OR user_id IN
(SELECT user_id from $follows)
ORDER BY created_at DESC", [$user->id, $user->id]);
*/
return response()->json($res);
}
This is a query which returns the posts from the logged user and from people the user follow
The followers table (the one in MongoDB) contains "user_id" and "follows_id"
The commented line is the original query (every table in one single database on mySql
Thank you
Edit: I solved through a query in mongodb, then I edited the result to get an array which I incorporated into the sql query through orWhereIn Thank you for your answers :)
I don't think so... you may try a true multimodel database such as Oracle XE (it's free) to achieve your goal here...
I'm making a reservation system for a media library, the goal is to book a room for a certain time. There are 8 time slots in total with a start_time & end_time.
The user has to fill in a date and I have to check what time slots are still available at that date.
So, for example.. there can only be one row in the database that contains date: 2016-12-08 time_slot: 3.
How do I check if this row exists in my database using Eloquent?
You can do laravel model query to check if there is any results, like this :
$data = Model::where('date','2016-12-08 ')->where('time_slot', 3)->count();
Assuming you have a slot table with the fields you are sharing. Slot table: id, date, time_slot...
$your_date = 2016-12-08;
$date = date('Y-m-d', strtotime($your_date));
$time_slot: 3;
$slot = Slot::where('date', $date)->where('slot', $time_slot)->first();
if($slot == null) {
// book can be made
}
else {
// already booked
}
You can take the help pf Laravel Query Builder's exists for checking the if the fields are present in database like this:
$exists = Model::whereDate('date', '2016-12-08')
->where('time_slot', 3)
->exists();
Here exists returns a boolean value, which depends upon the existence of the query above!
Hope this helps!
I have two tables 'approval' and 'renewal', both having a common column 'applicant_id'.
When new application comes-in, it stores a data-record in table 'approval' alongwith the 'applicant_id' for whom the record has been added.
Now, when there is a renew applied for that same applicant, the row gets created in the table 'renewal' referencing the 'applicant_id'
Note: There can be a single record in the table 'approval' for a 'applicant_id' but there can be more than one record for the same 'applicant_id' in the table 'renewal'.
Now, my requirement is:
I need to fetch the records from both the table for all the applicants.
Conditions: If there is a data for the 'applicant_id' in both the table and 'renewal' table has multiple row for the same 'applicant_id', then I need to get the records from 'renewal' table only that too the latest one.
If there is no data in 'renewal' table but exists in 'approval' table for the 'applicant_id', then the fetch record should get the data present in 'approval' table.
Basically, if there is record for the applicant in 'renewal' table, get the latest one from there, if there is record present only in 'approval' table, then get that one but the preference should be to get from 'renewal' if exists.
I am trying to do this in laravel 5.2. So, is there anyone who can help me in this?
If you're using Eloquent, you'll have 2 models:
Renewal.php
<?php
namespace App;
use Illuminate\Eloquent\Model;
class Renewal extends Model
{
protected $table = 'renewal';
public static function findMostRecentByApplicantId($applicantId)
{
$applicant = self::where('applicant_id', '=', $applicantId)
->orderBy('date_created', 'desc')
->first();
return $applicant;
}
}
Approval.php
<?php
namespace App;
use Illuminate\Eloquent\Model;
class Approval extends Model
{
protected $table = 'approval';
public static function findByApplicantId($applicantId)
{
$applicant = self::where('applicant_id', '=', $applicantId)
->first();
return $applicant;
}
}
Then, in the code where you want to get the approval/renewal record, use the following code:
if (! $record = Renewal::findMostRecentByApplicantId($applicantId)) {
$record = Approval::findByApplicantId($applicantId);
}
//$record will now either contain a valid record (approval or renewal)
//or will be NULL if no record exists for the specified $applicantId
After few try, I got one way to do it using raw:
SELECT applicant_id, applicant_name, applicant_email, applicant_phone, renewed, updated_at
FROM (
SELECT renewal_informations.applicant_id, renewal_informations.applicant_name, renewal_informations.applicant_email, renewal_informations.applicant_phone, renewal_informations.renewed, renewal_informations.updated_at
FROM renewal_informations
UNION ALL
SELECT approval_informations.applicant_id, approval_informations.applicant_name, approval_informations.applicant_email, approval_informations.applicant_phone, approval_informations.renewed, approval_informations.updated_at
FROM approval_informations
) result
GROUP BY applicant_id
ORDER BY applicant_id ASC, updated_at DESC;
For every single Approval id, there can b multiple records for renewal table suggests you have One to Many relation. which you can define in the your Model like
Approval.php (App\Models\Approval)
public function renewal()
{
return $this->hasMany('App\Models\Renewal', 'applicant_id')
}
Having defined this relation. you can get the records from the table using applicant_id.
$renewal_request_records = Approval::find($applicant_id)->renewal();
This will get all records from renewal table against that applicant_id.
Finding the latest
$latest = Renewal::orderBy('desc', 'renewal_id')->first();

I built up a pivot table containing ids of tables I want to associate. When I have the id of a specific item, I now want to get the latest entry of this item saved in the pivot table. For example:
Table 1: Tickets
Table 2: Status
Table 3: Ticket_Status (Pivot)
If I add a new entry to the pivot table, I would have something like this:
Pivot
ticketId, statusId
1, 2
1, 3
2, 1
Now I want to receive the latest status in the pivot for Ticket Id 1 for example, so I expect to receive statusId 3 for ticket 1. But how do I do this in Laravel?
Creating the entries for the pivot table works:
public function attachDispatchStatus($id) {
$this->status()->attach($id);
$this->touch();
}
// set fields on the eloquent object and save to database
// raise event that the incident was created.
public function createDispatch($command) {
// Get BodyContent from POST Request
$this->dispatchReference = $command->dispatchReference;
$this->incidentReference = $command->incidentReference;
// Create new Dispatch
$dispatch = Dispatch::create(array(
'dispatch_reference' => $this->dispatchReference,
'incident_reference' => $this->incidentReference
));
$dispatchStatus = DispatchStatus::where('status', '=', 'processing')->first();
$dispatch->attachDispatchStatus($dispatchStatus->id);
return $this;
}
Why don't you use the updateExistingPivot($roleId, $attributes); available in Laravel 5 when editing your tickets ?
This will solve your problem and make your database lighter :)
Check Larvel Doc for some examples on pivot table.
If you don't want to make it like that (because you want to keep an historic of your input), I think you will have to add an dateTime field in your pivot table... Then, just order by date, and you will be fine.
I searched enough before posting it.
My table structure:
aid | bid | cid | did |
Where aid, bid together are the primary keys.
When I update the value of cid using a where clause for aid, bid I also want to get the did value of the updated row.
Something like this:
$this->db->set('cid', 1, FALSE)
->where(array(
'aid' => $a_id,
'bid' => $b_id
))
->update('my_table')
->select('did');
The above query says:
Fatal error: Call to a member function select() on a non-object in...
I tried this:
How to get ID of the last updated row in MySQL?
Which is like 3 queries.
I'd suggest fetching the values you're about to update, store their IDs in an array, and run an UPDATE with a WHERE id IN (1, 2, ...).
What you're trying to do is not supported by MySQL. You'll need to run at least 2 queries, and since you're fetching the values the first time and already know what values you're updating, then you can also recreate the new row and it's values without using a query after UPDATE.
In your given example:
$this->db->set('cid', 1, FALSE)
->where(array(
'aid' => $a_id,
'bid' => $b_id
))
->update('my_table')
->select('did');
set(), where() and also select() returns an object that builds on the query. However update() return a value which is the results and doesn't have a function called select() and not set() and where() for that matter.
