how can I write SELECT IF(1>2,2,3); in this->find('all', array()) format in cakephp 2?
You can try like this:
$data = $this->Model->find("all", array(
"fields" => array("IF( 1 > 2 ,2, 3) AS result"),
"conditions" => ...
));
This will give your output in result index of your array.
Hope this will help!

I have two dates 30-01-2017 & 02-02-2017
Need a condition in cakephp to search record these two dates doesn't lies in between.
Please use this.I think this would be helpful.
$searchFirstdate = '30-01-2017';
$searchLastdate = '02-02-2017';
$this->ModelName->find(
'all',array(
'conditions'=>array(
'ModelName .date_field >= ' => $searchFirstdate,
'ModelName .date_field <= ' => $searchLastdate
)
)
);
There is a NOT BETWEEN operand for MYSQL, so you could easily use:
$this->ModelName->find('all', array(
'conditions' => array(
'ModelName.date_field NOT BETWEEN ? AND ?' => array('30-01-2017', '02-02-2017')
)
));
From CakePHP Manual
I am running the following query on my database:-
SELECT COUNT(*) AS COUNT, `Doctor`.`device_type` FROM `doctors` AS `Doctor` WHERE 1 = 1 GROUP BY `Doctor`.`device_type`
and it gives the result:-
count device_type
47 Android
23 iPhone
Whereas when running this query as a CakePHP query it gives the result as '2':-
$this->Doctor->find('count',array('group'=>'Doctor.device_type'));
Can anyone please suggest why this is happening?
The CakePHP result is correct as it is returning a count of the number of results returned by your query. In your case you have 2 rows: 'Android' and 'iPhone'.
find('count') always returns an integer, not an array. What Cake is doing is basically this:-
$data = $this->Doctor->find('all', array('group' => 'Doctor.device_type'));
$count = count($data); // This is what find('count') will return.
You need to do something like the following instead:-
$data = $this->Doctor->find('all', array(
'fields' => array(
'Doctor.device_type',
'COUNT(Doctor.*) AS count'
)
'group' => 'Doctor.device_type'
));
i got the following cakephp find situation:
$data = $this->find('all', array(
'conditions' => array(
'Roster.league_id' => $league_id,
'Roster.season' => $season,
),
'fields' => array(
'DISTINCT Roster.player_id',
'Roster.league_id',
'Roster.fflteam_id',
'Roster.season',
'Roster.modified',
'Fflteam.name',
'Player.firstName',
'Player.lastName',
'Player.position'
),
'order' => array(
'Roster.player_id',
'Roster.modified DESC'),
'contain' => array(
'Fflteam',
'Player' => array(
'Stat' => array(
'conditions' => array(
'Stat.season' => $season),
'Scores'),
'Teamplayer')
)
));
There are more Roster-records with specific player_ids, thats why i try to use DISTINCT. I only need the most recent. Thats why i order the results by player_id and Roster.modified. But die DISTINCT command gets ignored.
e.g:
records:
id=1 player_id=1 modified=2012
id=2 player_id=1 modified=2013
id=3 player_id=1 modified=2014
id=4 player_id=2 modified=2014
id=5 player_id=2 modified=2013
result should be:
id=3 player_id=1 modified=2014
id=4 player_id=2 modified=2014
I don't see any syntax errors. Maybe there some commands are not possible together or my way of filtering is wrong. would be great if someone can help me.
DISTINCT does not give you one distinct field if there are multiple fields , if you have Distinct title it will provides distinct title .
If you have distinct id , title it will output distinct combination of rows with same id and title.
This is how DISTINCT works.
Try GroupBy

As AgRizzo suggested i am using a query now.
Its split into 2 Parts. The first gets all entries with the one2one relations:
$this->query("SELECT *
FROM (SELECT * FROM `rosters` AS `Roster1` WHERE " . $conditions . " ORDER BY `Roster1`.`modified` DESC) AS `Roster`
LEFT JOIN `fflteams` AS `Fflteam` ON (`Roster`.`fflteam_id` = `Fflteam`.`id`)
LEFT JOIN `players` AS `Player` ON (`Roster`.`player_id` = `Player`.`id`)
GROUP BY `Player`.`id` ORDER BY `Roster`.`player_id` ASC");
The second part gets all one2many relations with its relation:
$this->Stat->find('all', array(
'conditions' => $conditions,
'contain' => array(
'Scores')
));
at the end i merge those 2 arrays
I am building a small Web App that lets users reserve Office Rooms and Equipment. For the Reservation they enter a Start and an End Date.
When a user tries to find out if any (for example) car is available on 2012-10-23, and the database holds reservation date records of Start: 2012-10-20 and End: 2012-10-25 for (lets say) all the cars, how do I include all the dates between my date entries in the search?
The $date variable gets it's value from the Date Search Form Field.
This, unfortunately does not work, and I can't figure out how to use daysAsSql for this query:
$conditions = array(
'conditions' => array(
'? BETWEEN ? AND ?' => array($date,'Equipment.date_start','Equipment.date_end'),
)));
$this->set('equipments', $this->Equipment->find('all', $conditions));
There is a simpler solution to this, but thanks for the help:
(As a condition in the find:)
array('Equipment.date_start <= ' => $date,
'Equipment.date_end >= ' => $date
),
In case if you have one date and you want to use BETWEEN
$date_start = start date;
$date_end = date_end;
$conditions = array(
'conditions' => array(
'date(Equipment.create) BETWEEN ? AND ?' => array($date_start, $date_end),
)));
$this->set('equipments', $this->Equipment->find('all', $conditions));
This is the case if you have From AND To
in your case
$date_start = start date;
$date_end = date_end;
$conditions = array(
'conditions' => array(
'Equipment.start_date >=' => array($date_start),
'Equipment.end_date <=' => array($date_end)
));
$this->set('equipments', $this->Equipment->find('all', $conditions));
Here is CakePHP BETWEEN query example.
I'm defining my arrays as variables, and then using those variables in my CakePHP find function call:
// just return these two fields
$fields = array('uri', 'page_views');
// use this "between" range
$conditions = array('Event.date BETWEEN ? and ?' => array($start_date, $end_date));
// run the "select between" query
$results = $this->Event->find('all',
array('fields'=>$fields,
'conditions'=>$conditions));
Ref from
$start = date('Y-m-d');
$end = date('Y-m-d', strtotime('+1 month'));
$conditions = array('Event.start <=' => $end, 'Event.end >=' => $start);
$this->Event->find('all', array('conditions' => $conditions));
If you are on cakephp 2.0 this is the answer http://book.cakephp.org/2.0/en/core-libraries/helpers/time.html#TimeHelper::daysAsSql
If you are on cakephp 1.3 you can use TimeHelper, just import it and use the same function as per example in documentation here http://book.cakephp.org/1.3/en/view/1471/Formatting
You cannot use database columns with this BETWEEN-syntax. If you assign strings in the array, CakePHP will quote them. Same for numeric values depending on your database setup.
CakePHP will quote the numeric values depending on the field type in your DB.
– see http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#complex-find-conditions
If you still want to use the BETWEEN, you can write your queries into the array key because CakePHP will not escape the keys, but only the values.
CakePHP only escapes the array values. You should never put user data into the keys. Doing so will make you vulnerable to SQL injections.
– see http://book.cakephp.org/2.0/en/models/retrieving-your-data.html#complex-find-conditions
Concerning your problem:
$this->Model->find('all', array(
'conditions' => array(
'"YYYY-MM-DD" BETWEEN Model.date_start AND Model.date_end',
),
));
You can even work with MySQL date and time functions:
$this->Model->find('all', array(
'conditions' => array(
'CURDATE() BETWEEN Model.date_start AND Model.date_end',
),
));
If you use date/time functions, do not quote them. If you use a specific date put it in quotes.
$v = array(1,11.38,15.8);
$sortByPrice = $this->Product->query
(
"SELECT *,
CASE `currency`
WHEN '1' THEN $v[0]
WHEN '2' THEN $v[1]
WHEN '3' THEN $v[2]
END AS 'ratio'
FROM products
ORDER BY price*ratio DESC
"
);
i want to convert what is above to a find function
i tried something like that(but it do not work)..
$v = array(1,11.38,15.8);
$bla = $this->Product->find('all', array(
'conditions' => array(
'Product.currency',
'((
CASE WHEN
Product.currency=1 THEN $v[0]
Product.currency=2 THEN $v[1]
Product.currency=3 THEN $v[2]
END
)) AS ratio'),
'order' => 'ratio',
'limit' => 10
));
can somebody to convert query into find
You are putting into the conditions key. Move it into the fields key or make it a virtualField - that may work.
Edit: also $v[0] in single quotes will not actually replace it with the variable - it will just appear as that text.
