It's possible update multiple columns in one line with laravel 5.4?
I try to this
DB::table('Home_Content')->where('id',1)->update(
[$_POST['name'] => $_POST['content']],
[$_POST['title'] => $_POST['titleMsg']]
);
only 1st part is work([$_POST['name'] => $_POST['content']])
server not return any error, but only 1st part is success.
Update method syntax in Laravel is like so :
DB::table('users')
->where('id', 1)
->update(['options->enabled' => true]);
Which means the values we want to update are inside an array, what I've seen is that you separated what you want to update into two arrays
DB::table('Home_Content')->where('id',1)->update(
[$_POST['name'] => $_POST['content']],
[$_POST['title'] => $_POST['titleMsg']]
);
so now you are out of the array
Your code should be like this
DB::table('Home_Content')->where('id',1)->update([
$_POST['name'] => $_POST['content'],
$_POST['title'] => $_POST['titleMsg']
]);
Meaning each pair has a key and a value and separated with comma
If you want to update record in multiple row with id as Array() use following query.
DB::table('users')
->whereIn('id', [1,2,3])
->update(['status' => 1]);

I'm updating a record in this way:
Yii::$app->db->createCommand()->update('table', ['config' => json_encode($array)],
'field1 = :field1', [':field1' => $field1]
)->execute();
My aim is to add an extra condition with the AND operator but I don't know how to do it.
I've followed this example: LINK
// UPDATE (table name, column values, condition)
Yii::$app->db->createCommand()->update('user', ['status' => 1], 'age > 30')->execute();
But it doesn't show a lot of possibilities.
try this way
Yii::$app->db->createCommand()
->update('table', ['config' => json_encode($array)],
'field1 = :field1 AND field2 = :field2',[':field1' => $field1,':field2' => $field2])
->execute();
Just like an array, with each condition separated by a ,.
In your case:
Yii::$app->db->createCommand()->update(
'table',
['config' => json_encode($array)],
['field1' => $field1, 'field2' => $field2]
)->execute();
Note that with this syntax you don't need to bind params, you could specify them directly inside the array of conditions as Yii2 santizes them.
Already received a great answer at this post
Laravel Query using GroupBy with distinct traits
But how can I modify it to include more than just one field. The example uses pluck which can only grab one field.
I have tried to do something like this to add multiple fields to the view as such...
$hats = $hatData->groupBy('style')
->map(function ($item){
return ['colors' => $item->color, 'price' => $item->price,'itemNumber'=>$item->itemNumber];
});
In my initial query for "hatData" I can see the fields are all there but yet I get an error saying that 'colors', (etc.) is not available on this collection instance. I can see the collection looks different than what is obtained from pluck, so it looks like when I need more fields and cant use pluck I have to format the map differently but cant see how. Can anyone explain how I can request multiple fields as well as output them on the view rather than just one field as in the original question? Thanks!
When you use groupBy() of Laravel Illuminate\Support\Collection it gives you a deeper nested arrays/objects, so that you need to do more than one map on the result in order to unveil the real models (or arrays).
I will demo this with an example of a nested collection:
$collect = collect([
collect([
'name' => 'abc',
'age' => 1
]),collect([
'name' => 'cde',
'age' => 5
]),collect([
'name' => 'abcde',
'age' => 2
]),collect([
'name' => 'cde',
'age' => 7
]),
]);
$group = $collect->groupBy('name')->values();
$result = $group->map(function($items, $key){
// here we have uncovered the first level of the group
// $key is the group names which is the key to each group
return $items->map(function ($item){
//This second level opens EACH group (or array) in my case:
return $item['age'];
});
});
The summary is that, you need another loop map(), each() over the main grouped collection.
I am using Cakephp 3.x and i want to update my single field for multiple ids. Something like this..
UPDATE mytable SET `status` = '1' WHERE ID IN (1,2,3)
Currently i am using query to perform this action using cakpehp
$this->Leaveregisters->query()
->update()
->set(['leaveregister_status' => $this->request->data('status')])
->where(['leaveregister_id IN ('.$this->request->data('final_ids_string').')'])
->execute();
Well this does the trick for me but i want this to be performed using cakephp 3.xs' ORM method .. so i am trying to use this instead
$table->updateAll(['field' => $newValue], ['id' => $entityId]);
But this code is for single id only which i do not want.. i also do not want to use foeach loop to perform the same action. Instead i want an ID to be passed via array or comma seperated in any case and want to perform the same action.
Is there any way i can perform the same thing using ORM method using cakephp 3.x
Thanks
usinga updateAll or a query() objects to do a bulk update is the same thing as you can read in the manual at the end of this paragraph
so you can do
$this->Leaveregisters->query()
->update()
->set(['leaveregister_status' => $this->request->data('status')])
->where(['leaveregister_id IN' => [1,2,3])
->execute();
or
$this->Leaveregisters->updateAll(
['leaveregister_status' => $this->request->data('status')]
['leaveregister_id IN' => [1,2,3]);
remember then when usin IN clause you have to pass an array. Read this part of the manual on how to create IN clause
You have to use array datatype for pass in IN CLAUSE
$in_condition= explode(",",$this->request->data('final_ids_string'));
$this->Leaveregisters->query()
->update()
->set(['leaveregister_status' => $this->request->data('status')])
->where(['leaveregister_id IN' => $in_condition])
->execute();
With updateAll() of Model
$table->updateAll(array(
// new values
),
array('id' => array(1,2,3,4,5,6))
);
I have an array of objects fetched from database:
$masterListContacts = MasterListContacts::find()
->select('master_list_contacts.*')
->innerJoin('master_contacts', '`master_contacts`.`id` = `master_list_contacts`.`master_contact_id`')
->with('masterContact')
->where(['user_id' => \Yii::$app->user->identity->id, 'slug' => $slug])
->all();
Under certain circumstances, I need to delete all rows from the database represented in this array. But with both delete() and deleteAll() methods I got an error Call to a member function ... on array. Could someone tell me please which one is the best way to accomplish this?
UPDATE:
Here is my database structure.
Found better solution:
\Yii::$app
->db
->createCommand()
->delete('master_contacts', ['id' => $deletableMasterContacts])
->execute();
Where $deletableMasterContacts is array of master_contacts ids, which should be deleted
You can painlessly remove ->select('master_list_contacts.*').
->innerJoin('master_contacts', '`master_contacts`.`id` = `master_list_contacts`.`master_contact_id`')
performs the same work that ->joinWith('masterContact').
For delete entites try use this code:
MasterListContacts::deleteAll(['user_id' => \Yii::$app->user->identity->id, 'slug' => $slug]);
Alright, so i have a huge list (like 500+) of entries in an array that i need to insert into a MySQL database.
I have a loop that populates an array, like this:
$sms_to_insert[] = array(
'text' => $text,
'contact_id' => $contact_id,
'pending' => $status,
'date' => $date,
'user_id' => $this->userId,
'sent' => "1"
);
And then i send it to the database using the built insert_batch() function:
public function add_sms_for_user($id, $sms) {
//$this->db->delete('sms', array("user_id" => $id)); Irrelevant
$this->db->insert_batch('sms', $sms); // <- This!
}
The error message i get is as follows:
Column count doesn't match value count at row 1.
Now, that doesn't make sense at all. The columns are the same as the keys in the array, and the values are the keys value. So, why is it not working?
Any ideas?
user_id turned out to be null in some situations, that's what caused the error.
EDIT: If you replace insert_batch() with a loop that runs insert() on the array keys you will get more clear error messages.
