How do I use the created_at field to get only the records that were created today and no other day or time?
I was thinking of a ->where('created_at', '>=', Carbon::now()) But Im not sure that would work.
For Laravel 5.6+ users, you can just do
$posts = Post::whereDate('created_at', Carbon::today())->get();
Use Mysql default CURDATE function to get all the records of the day.
$records = DB::table('users')->select(DB::raw('*'))
->whereRaw('Date(created_at) = CURDATE()')->get();
dd($record);
Note
The difference between Carbon::now vs Carbon::today is just time.
e.g
Date printed through Carbon::now will look like something:
2018-06-26 07:39:10.804786 UTC (+00:00)
While with Carbon::today:
2018-06-26 00:00:00.0 UTC (+00:00)
To get the only records created today with now can be fetched as:
Post::whereDate('created_at', Carbon::now()->format('m/d/Y'))->get();
while with today:
Post::whereDate('created_at', Carbon::today())->get();
UPDATE
As of laravel 5.3, We have default where clause
whereDate / whereMonth / whereDay / whereYear
$users = User::whereDate('created_at', DB::raw('CURDATE()'))->get();
OR with DB facade
$users = DB::table('users')->whereDate('created_at', DB::raw('CURDATE()'))->get();
Usage of the above listed where clauses
$users = User::whereMonth('created_at', date('m'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->month;
//select * from `users` where month(`created_at`) = "04"
$users = User::whereDay('created_at', date('d'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->day;
//select * from `users` where day(`created_at`) = "03"
$users = User::whereYear('created_at', date('Y'))->get();
//or you could also just use $carbon = \Carbon\Carbon::now(); $carbon->year;
//select * from `users` where year(`created_at`) = "2017"
Query Builder Docs
If you are using Carbon (and you should, it's awesome!) with Laravel, you can simply do the following:
->where('created_at', '>=', Carbon::today())
Besides now() and today(), you can also use yesterday() and tomorrow() and then use the following:
startOfDay()/endOfDay()
startOfWeek()/endOfWeek()
startOfMonth()/endOfMonth()
startOfYear()/endOfYear()
startOfDecade()/endOfDecade()
startOfCentury()/endOfCentury()
with carbon:
return $model->where('created_at', '>=', \Carbon::today()->toDateString());
without carbon:
return $model->where('created_at', '>=', date('Y-m-d').' 00:00:00');
You can use
whereRaw('date(created_at) = curdate()')
if the timezone is not a concern or
whereRaw('date(created_at) = ?', [Carbon::now()->format('Y-m-d')] )
otherwise.
Since the created_at field is a timestamp, you need to get only the date part of it and ignore the time part.
Laravel ^5.6 - Query Scopes
For readability purposes i use query scope, makes my code more declarative.
scope query
namespace App\Models;
use Illuminate\Support\Carbon;
use Illuminate\Database\Eloquent\Model;
class MyModel extends Model
{
// ...
/**
* Scope a query to only include today's entries.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeCreatedToday($query)
{
return $query->where('created_at', '>=', Carbon::today());
}
// ...
}
example of usage
MyModel::createdToday()->get()
SQL generated
Sql : select * from "my_models" where "created_at" >= ?
Bindings : ["2019-10-22T00:00:00.000000Z"]
$today = Carbon\Carbon::now()->format('Y-m-d').'%';
->where('created_at', 'like', $today);
Hope it will help you
No need to use Carbon::today because laravel uses function now() instead as a helper function
So to get any records that have been created today you can use the below code:
Model::whereDay('created_at', now()->day)->get();
You need to use whereDate so created_at will be converted to date.
simple solution:
->where('created_at', 'like', date("Y-m-d")."%");
I’ve seen people doing it with raw queries, like this:
$q->where(DB::raw("DATE(created_at) = '".date('Y-m-d')."'"));
Or without raw queries by datetime, like this:
$q->where('created_at', '>=', date('Y-m-d').' 00:00:00'));
Luckily, Laravel Query Builder offers a more Eloquent solution:
$q->whereDate('created_at', '=', date('Y-m-d'));
Or, of course, instead of PHP date() you can use Carbon:
$q->whereDate('created_at', '=', Carbon::today()->toDateString());
It’s not only whereDate. There are three more useful functions to filter out dates:
$q->whereDay('created_at', '=', date('d'));
$q->whereMonth('created_at', '=', date('m'));
$q->whereYear('created_at', '=', date('Y'));
Below code worked for me
$today_start = Carbon::now()->format('Y-m-d 00:00:00');
$today_end = Carbon::now()->format('Y-m-d 23:59:59');
$start_activity = MarketingActivity::whereBetween('created_at', [$today_start, $today_end])
->orderBy('id', 'ASC')->limit(1)->get();
Carbon::today() will return something like this: 2021-08-06T00:00:00.000000Z, so using Model::where('created_at', Carbon::today()) will only return records created at exactly 12:00 am current date.
Use Model::where('created_at', '>=', Carbon::today()) instead
Post::whereDate('created_at', '=', date('Y-m-d'))->get();
It will give you All the posts created today !!!!! if you use time with this you will get posts of that particular time not of today
laravel 8
$VisitorEntryStatusDateCurrent = VisitorEntry::whereDate('created_at', Carbon::today())->get();
$records = User::where('created_at' = CURDATE())->GET());
print($records);
I use laravel9 on 22 Apr 2022
how I get the "today" record is :
I have edit "config/app.php" on the "timezone" (about line 72 ) I have set it to my timezone which is "Asia/Bangkok"
my query code I have is :
$get = User::whereDate("created_at","=",date("Y-m-d",time() ) )->get();
will get the field that created today.
I don't know if this a correct way or it another bad code but as long as it work for me I will be okay.
Is it possible to do a "BETWEEN ? AND ?" where condition LIKE in cakephp 2.5?
In cakephp 2.5 I write something like
'conditions' => ['start_date BETWEEN ? AND ?' => ['2014-01-01', '2014-12-32']]
how can I migrate that?
additionally I would write something like
'conditions' => [ '? BETWEEN start_date AND end_date'] => '2014-03-31']
Expressions
Between expression are supported out of the box, however they only support the first case without additional fiddling:
$Query = $Table
->find()
->where(function($exp) {
return $exp->between('start_date', '2014-01-01', '2014-12-32', 'date');
});
If you'd wanted to handle the second case via the between method, then you'd have to pass all values as expressions, which can easily go wrong, as they will not be subject to escaping/parameter binding in that case, you'd have to do that on your own (which is anything but recommended! See the security notes in the manual for PDO::quote()), something along the lines of:
use Cake\Database\Expression\IdentifierExpression;
use Cake\Database\Expression\QueryExpression;
use Cake\ORM\Query;
// ...
$Query = $Table
->find()
->where(function(QueryExpression $exp, Query $query) {
return $exp->between(
$query->newExpr(
$query->connection()->driver()->quote(
'2014-03-31',
\PDO::PARAM_STR
)
),
new IdentifierExpression('start_date'),
new IdentifierExpression('end_date')
);
});
That might feel a little inconvenient for such a basic SQL expression that is supported by all SQL dialects that CakePHP ships with, so you may have a reason here to use a raw SQL snippet with value bindig instead.
It should be noted however that expressions are often the better choice when it comes to for example cross dialect support, as they can be (more or less) easily transformed at compile time, see the implementations of SqlDialectTrait::_expressionTranslators(). Also expressions usually support automatic identifier quoting.
Value binding
Via manual value binding you can pretty much create anything you like. It should however be noted that whenever possible, you should use expressions instead, as they are easier to port, which happens out of the box for quite a few expressions already.
$Query = $Table
->find()
->where([
'start_date BETWEEN :start AND :end'
])
->bind(':start', '2014-01-01', 'date')
->bind(':end', '2014-12-31', 'date');
That way the second case can also be solved very easily, like:
$Query = $Table
->find()
->where([
':date BETWEEN start_date AND end_date'
])
->bind(':date', '2014-03-31', 'date');
A mixture of both (safest and most compatible approach)
It's also possible to mix both, ie use an expression that makes use of custom bindings, something along the lines of this:
use Cake\Database\Expression\IdentifierExpression;
use Cake\Database\Expression\QueryExpression;
use Cake\ORM\Query;
// ...
$Query = $Table
->find()
->where(function(QueryExpression $exp, Query $query) {
return $exp->between(
$query->newExpr(':date'),
new IdentifierExpression('start_date'),
new IdentifierExpression('end_date')
);
})
->bind(':date', '2014-03-31', 'date');
That way you could handle the second case using possibly portable expressions, and don't have to worry about quoting/escaping input data and identifiers manually.
Regular comparison using array syntax
All that being said, in the end BETWEEN is just the same as using two separate simple conditions like this:
$Query = $Table
->find()
->where([
'start_date >=' => '2014-01-01',
'start_date <=' => '2014-12-32',
]);
$Query = $Table
->find()
->where([
'start_date >=' => '2014-03-31',
'end_date <=' => '2014-03-31',
]);
But don't be mad, if you read all the way down to here, at least you learned something about the ins and outs of the query builder.
See also
Cookbook > Database Access & ORM > Query Builder > Advanced Conditions
API > \Cake\Database\Query::bind()
Currently there seems to be only two options. The core now supports this out of the box, the following is just kept for reference.
Value binding (via the database query builder)
For now the ORM query builder (Cake\ORM\Query), the one that is being retrived when invoking for example find() on a table object, doesn't support value binding
https://github.com/cakephp/cakephp/issues/4926
So, for being able to use bindings you'd have to use the underlying database query builder (Cake\Database\Query), which can for example be retrived via Connection::newQuery().
Here's an example:
$conn = ConnectionManager::get('default');
$Query = $conn->newQuery();
$Query
->select('*')
->from('table_name')
->where([
'start_date BETWEEN :start AND :end'
])
->bind(':start', new \DateTime('2014-01-01'), 'date')
->bind(':end', new \DateTime('2014-12-31'), 'date');
debug($Query->execute()->fetchAll());
This would result in a query similar to this
SELECT
*
FROM
table_name
WHERE
start_date BETWEEN '2014-01-01' AND '2014-12-31'
A custom expression class
Another option would be a custom expression class that generates appropriate SQL snippets. Here's an example.
Column names should be wrapped into identifier expression objects in order to them be auto quoted (in case auto quoting is enabled), the key > value array syntax is for binding values, where the array key is the actual value, and the array value is the datatype.
Please note that it's not safe to directly pass user input for column names, as they are not being escaped! Use a whitelist or similar to make sure the column name is safe to use!
Field between values
use App\Database\Expression\BetweenComparison;
use Cake\Database\Expression\IdentifierExpression;
// ...
$between = new BetweenComparison(
new IdentifierExpression('created'),
['2014-01-01' => 'date'],
['2014-12-31' => 'date']
);
$TableName = TableRegistry::get('TableName');
$Query = $TableName
->find()
->where($between);
debug($Query->execute()->fetchAll());
This would generate a query similar to the one above.
Value between fields
use App\Database\Expression\BetweenComparison;
use Cake\Database\Expression\IdentifierExpression;
// ...
$between = new BetweenComparison(
['2014-03-31' => 'date'],
new IdentifierExpression('start_date'),
new IdentifierExpression('end_date')
);
$TableName = TableRegistry::get('TableName');
$Query = $TableName
->find()
->where($between);
debug($Query->execute()->fetchAll());
This on the other hand would result in a query similar to this
SELECT
*
FROM
table_name
WHERE
'2014-03-31' BETWEEN start_date AND end_date
The expression class
namespace App\Database\Expression;
use Cake\Database\ExpressionInterface;
use Cake\Database\ValueBinder;
class BetweenComparison implements ExpressionInterface {
protected $_field;
protected $_valueA;
protected $_valueB;
public function __construct($field, $valueA, $valueB) {
$this->_field = $field;
$this->_valueA = $valueA;
$this->_valueB = $valueB;
}
public function sql(ValueBinder $generator) {
$field = $this->_compilePart($this->_field, $generator);
$valueA = $this->_compilePart($this->_valueA, $generator);
$valueB = $this->_compilePart($this->_valueB, $generator);
return sprintf('%s BETWEEN %s AND %s', $field, $valueA, $valueB);
}
public function traverse(callable $callable) {
$this->_traversePart($this->_field, $callable);
$this->_traversePart($this->_valueA, $callable);
$this->_traversePart($this->_valueB, $callable);
}
protected function _bindValue($value, $generator, $type) {
$placeholder = $generator->placeholder('c');
$generator->bind($placeholder, $value, $type);
return $placeholder;
}
protected function _compilePart($value, $generator) {
if ($value instanceof ExpressionInterface) {
return $value->sql($generator);
} else if(is_array($value)) {
return $this->_bindValue(key($value), $generator, current($value));
}
return $value;
}
protected function _traversePart($value, callable $callable) {
if ($value instanceof ExpressionInterface) {
$callable($value);
$value->traverse($callable);
}
}
}
You can use one of following 2 methods.
Method 1 :
$start_date = '2014-01-01 00:00:00';
$end_date = '2014-12-31 23:59:59';
$query = $this->Table->find('all')
->where(function ($exp, $q) use($start_date,$end_date) {
return $exp->between('start_date', $start_date, $end_date);
});
$result = $query->toArray();
Method 2:
$start_date = '2014-01-01 00:00:00';
$end_date = '2014-12-31 23:59:59';
$query = $this->Table->find('all')
->where([
'start_date BETWEEN :start AND :end'
])
->bind(':start', new \DateTime($start_date), 'datetime')
->bind(':end', new \DateTime($end_date), 'datetime');
$result = $query->toArray();
I'm using it like this
$this->Table->find()->where(['data_inicio BETWEEN '.'\''.$data_inicio.'\''.' AND .'\''.$data_final.'\''.' ']);
Hello guys please use this query to get data on the basis of range of value
$query = $this->Leads->find('all',
array('conditions'=>array('postcode BETWEEN '.$postcodeFrom.' and'.$postcodeTo.''), 'recursive'=>-1));
debug($query);
print_r($query->toArray());
I have 2 models
Truck
class Truck extends \Eloquent {
// Add your validation rules here
public static $rules = [
'trucktype_id' => 'required',
'weight'=> 'required',
'truck_no'=> 'required'
];
// Don't forget to fill this array
protected $fillable = ['trucktype_id','weight','picture_path','remarks','truck_no'];
public function TruckType(){
return $this->belongsTo('TruckType','trucktype_id');
}
}
TruckType
class Trucktype extends \Eloquent {
// Add your validation rules here
public static $rules = array(
'type' => 'required|unique:trucktypes,type',
'max_weight' => 'required'
);
// Don't forget to fill this array
protected $fillable = ['type','max_weight'];
}
I need to lookup related table records i.e TruckType
$trucksobj = Truck::with('TruckType');
if($truck_no!="")
$trucksobj->where("truck_no",'=',$truck_no);
if($start_date!="" && $end_date!="")
$trucksobj->whereBetween('created_at', array($start_date, $end_date));
if($truck_type!="")
$trucksobj->where("trucktype_id",'=',$truck_type);
if($overweight=="on")
$trucksobj->where('TruckType.max_weight', '>=', 0);
But the above query didnt resolve TruckType.max_weight and throws following error
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'TruckType.max_weight' in 'where clause' (SQL: select count(*) as aggregate from trucks where TruckType.max_weight >= 0)
I think you misunderstand how with() actually works. It is only used to alleviate the N+1 query problem, and does not make the contents of the table available for querying. After your first query has ran to select all of the trucks, the with() simply causes the following query to be automatically ran:
select * from TruckType where TruckType.id in (...)
Here the list at the end will contain all of the different truck.trucktype_id values that were found in your first query, and then they'll automatically be available for you to use via $truck->TruckType->{property} etc.
Now, if you actually have a look at the query that's being generated for you, you can clearly see that there is no TruckType table referenced anywhere:
select count(*) as aggregate from trucks where TruckType.max_weight >= 0
This is why the error is being thrown.
You have two options:
(1) Use a join
$trucksobj = Truck::with('TruckType')->join('TruckType', 'truck.trucktype_id', '=', 'TruckType.id')->where('TruckType.max_weight', '>=', 0);
(2) Use whereHas() to place a constraint on your relationship
$trucksobj = Truck::with('TruckType')->whereHas('TruckType', function($q) {
$q->where('max_weight', '>=', 0);
});
If you don't actually need to know anything about the truck type, and you only want to use it to sieve through the trucks, then you can get rid of with('TruckType') and just keep the rest of the query.
I'm trying to use the "HAVING" clause in a SQL query using the CakePHP paginate() method.
After some searching around it looks like this can't be achieved through Cake's paginate()/find() methods.
The code I have looks something like this:
$this->paginate = array(
'fields' => $fields,
'conditions' => $conditions,
'recursive' => 1,
'limit' => 10,
'order' => $order,
'group' => 'Venue.id');
One of the $fields is an alias "distance". I want to add a query for when distance < 25 (e.g. HAVING distance < 25).
I have seen two workarounds so far, unfortunately neither suit my needs. The two I've seen are:
1) Adding the HAVING clause in the "group" option. e.g. 'group' => 'Venue.id HAVING distance < 25'. This doesn't seem to work when used in conjunction with pagination as it messes up the initial count query that is performed. (ie tries to SELECT distinct(Venue.id HAVING distance < 25) which is obviously invalid syntax.
2) Adding the HAVING clause after the WHERE condition (e.g. WHERE 1 = 1 HAVING field > 25) This doesn't work as it seems the HAVING clause must come after the group statement which Cake is placing after the WHERE condition in the query it generates.
Does anyone know of a way to do this with CakePHP's find() method? I don't want to use query() as that would involve a lot of rework and also mean I'd need to implement my own pagination logic!
Thanks in advance
You have to put it with the group conditions. like this
$this->find('all', array(
'conditions' => array(
'Post.length >=' => 100
),
'fields' => array(
'Author.id', 'COUNT(*) as Total'
),
'group' => array(
'Total HAVING Total > 10'
)
));
Hope it helps you
I used the following trick to add my own HAVING clause at the end of my WHERE clause. The "dbo->expression()" method is mentioned in the cake sub-query documentation.
function addHaving(array $existingConditions, $havingClause) {
$model = 'User';
$db = $this->$model->getDataSource();
// Two fun things at play here,
// 1 - mysql doesn't allow you to use aliases in WHERE clause
// 2 - Cake doesn't allow a HAVING clause separate from a GROUP BY
// This expression should go last in the WHERE clause (following the last AND)
$taut = count($existingConditions) > 0 ? '1 = 1' : '';
$having = $db->expression("$taut HAVING $havingClause");
$existingConditions[] = $having;
return $existingConditions;
}
As per the manual, CakePHP/2 supports having at last. It was added as find array parameter on version 2.10.0, released on 22nd July 2017.
From the 2.10 Migration Guide:
Model::find() now supports having and lock options that enable you to
add HAVING and FOR UPDATE locking clauses to your find operations.
Just had the same problem. I know, one is not supposed to modify the internal code but if you open the PaginatorComponent and you modify line 188:
$count = $object->find('count', array_merge($parameters, $extra));
to this:
$count = $object->find(
'count',
array_merge(array("fields" => $fields),$parameters, $extra)
);
Everything will be fixed. You will be able to add your HAVING clause to the 'group' and the COUNT(*) won't be a problem.
Or, make line:
$count = $object->paginateCount($conditions, $recursive, $extra);
to include the $fields:
$count = $object->paginateCount($fields,$conditions, $recursive, $extra);
After that, you can "override" the method on the Model and make sure to include the $fields in the find() and that's it!, =P
Here is another idea that doesn't solve the pagination issue, but it is clean since it just overrides the find command in AppModel. Just add a group and having element to your query and this will convert to a HAVING clause.
public function find($type = 'first', $query = array()) {
if (!empty($query['having']) && is_array($query['having']) && !empty($query['group'])) {
if ($type == 'all') {
if (!is_array($query['group'])) {
$query['group'] = array($query['group']);
}
$ds = $this->getDataSource();
$having = $ds->conditions($query['having'], true, false);
$query['group'][count($query['group']) - 1] .= " HAVING $having";
CakeLog::write('debug', 'Model->find: out query=' . print_r($query, true));
} else {
unset($query['having']);
}
}
return parent::find($type, $query);
}
Found it here
https://groups.google.com/forum/?fromgroups=#!topic/tickets-cakephp/EYFxihwb55I
Using 'having' in find did not work for me. Instead I put into one string with the group
" group => product_id, color_id having sum(quantity) > 2000 " and works like a charm.
Using CakePHP 2.9
I have a large data set (over a billion rows). The data is partitioned in the database by date. As such, my query tool MUST specify an SQL between clause on every query, or it will have to scan every partition.. and well, it'll timeout before it ever comes back.
So.. my question is, the field in the database thats partitioned is a date..
Using CakePHP, how can I specify "between" dates in my form?
I was thinking about doing "start_date" and "end_date" in the form itself, but this may bring me two a second question.. how do I validate that in a model which is linked to a table?
If I am following you correctly:
The user must specify start/end dates for find queries generated from a form
You need to validate these dates so that, for example:
end date after start date
end date not centuries away from start date
You want validation errors appearing inline within the form (even though this isn't a save)
Since you want to validate these dates they will be harder to grab when they are tucked away inside your conditions array. I suggest trying to pass these in separately and then dealing with them later:
$this->Model->find('all', array(
'conditions' => array(/* normal conditions here */),
'dateRange' => array(
'start' => /* start_date value */,
'end' => /* end_date value */,
),
));
You should hopefully be able to handle everything else in the beforeFind filter:
public function beforeFind() {
// perform query validation
if ($queryData['dateRange']['end'] < $queryData['dateRange']['start']) {
$this->invalidate(
/* end_date field name */,
"End date must be after start date"
);
return false;
}
/* repeat for other validation */
// add between condition to query
$queryData['conditions'][] = array(
'Model.dateField BETWEEN ? AND ?' => array(
$queryData['dateRange']['start'],
$queryData['dateRange']['end'],
),
);
unset($queryData['dateRange']);
// proceed with find
return true;
}
I have not tried using Model::invalidate() during a find operation, so this might not even work. The idea is that if the form is created using FormHelper these messages should make it back next to the form fields.
Failing that, you might need to perform this validation in the controller and use Session::setFlash(). if so, you can also get rid of the beforeFind and put the BETWEEN condition array in with your other conditions.
if you want to find last 20 days data .
$this->loadModel('User');
//$this->User->recursive=-1;
$data=$this->User->find('all', array('recursive' => 0,
'fields' => array('Profile.last_name','Profile.first_name'),'limit' => 20,'order' => array('User.created DESC')));
other wise between two dates
$start = date('Y-m-d') ;
$end = date('Y-m-d', strtotime('-20 day'));
$conditions = array('User.created' =>array('Between',$start,$end));
$this->User->find("all",$conditions)
You could write a custom method in your model to search between the dates:
function findByDateRange($start,$end){
return $this->find('all',array('date >= '.$start,'data >= .'$end));
}
As far as validating, you could use the model's beforeValidate() callback to validate the two dates. More info on this here.
function beforeValidate(){
if(Validation::date($this->data['Model']['start_date'])){
return false;
}
if(Validation::date($this->data['Model']['end_date'])){
return false;
}
return parent::beforeValidate();
}
Does that answer your question?
