Question

I’m trying to update table data from a database in CakePHP.

Query:

UPDATE status SET amount=5000 WHERE id=3

How to write this query in CakePHP?

Answer 1

Take a look at documentation and see the CakePHP way of dealing with models (and database tables).

In this case I think you could use set() and save():

$this->Status->read(null, 3);
$this->Status->set('amount', 5000);
$this->Status->save();

or a shorter version with saveField():

$this->Status->id = 3; // This avoids the query performed by read()
$this->Status->saveField('amount', 5000);

The difference between them is that saveField() is kind of an atomic update, while multiple set() calls do not modify the data until you do a save() call.
