How to use agregate Mysql functions with CakePHP

There is a w开发者_如何学Pythonay to use agregate functions with cakephp? like sum() or avg() with find() method.

UPDATE:

I missed a line in the book

array('fields'=>array('Product.type','MIN(Product.price) as price'), 'group' => 'Product.type');

Showing the basic structure for doing that.

Thanks for the help

In the fields parameter of a find method call, you may pass the field processed by an aggregated function. Example:

$Model->find('all',
    array(
        'anything' => array(/* */),
        'fields' => array(
            'SUM (Model.attribute) AS total',
            'OTHERFUNCTION(OModel.other_attribute) AS other'
        ),
        'otherthing' => array(/* */)
    )
);

In exactly the same way, since CakePHP is just a PHP framework.

<?php
// Make a MySQL Connection

$query = "SELECT type, SUM(price) FROM products GROUP BY type"; 

$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){
    echo "Total ". $row['type']. " = $". $row['SUM(price)'];
    echo "<br />";
}
?>
