CakePHP，从模型查询

Question

How I can execute a SQL query in CakePHP.

I want to make some like this code

    $employees = $this->Employee->find('all');

but introducing my own SQL statment.

Answer 1

Insert into your Model a function that executes your SQL statment,

public function get_employees() {
     $sql = 'select * from employees';         
     $data = $this->query($sql);
     return $data;
 }

And call this function like this way:

 $employee = new Employee();
 $data = $employee->get_employees();

Answer 2

In model you can't write model name. Its already detected. Use only

$this->find('all');

Answer 3

Assuming your statement is inside EmployeesController.php

$employeeRows = $this->employee->find('all', array('conditions'=>array('id' => 100)));

if you are in another controller, you have to load the model before the find

$this->loadModel('employee');

if you are in a view, you can write a helper and use raw sql

The cakephp website also offers the following controller logic

$this->Picture->query("SELECT * FROM pictures LIMIT 2;");
