Zend Framework SQL update query

How would I write this SQL the Zend Framework way?

UPDATE register 
SET balance = (balance + 10) 
WHERE added_date > 12599441开发者_运维知识库84 ;

I can't find any examples of this on Zend's website or the web.

Do I need to use "Zend_Db_Expr"?

This worked for me:

$data = array(balance => new Zend_DB_Expr('balance + 10'));

$db->update('register ', $data, 'added_date > 1259944184');

acording to zend framwork documentation

use this

$data = array(
    'balance'      => 'balance + 10'
);

$n = $db->update('register ', $data, 'added_date > 1259944184');

Try this... make sure your model is ready.

$table = new register();

This is the model class

balance=balance+10;

$data = array( 'balance' => 'balance' );

$where = $table->getAdapter()->quoteInto('added_date > '. 1259944184 );

You can use $where[] for multiple conditions

$table->update($data, $where);

I used this to modify element order to top. Code as follow from the table class extending Zend_Db_Table_Abstract:

$data = array('i_order' => new Zend_DB_Expr('i_order + 1'));

return $this->getAdapter()->update($this->_name, $data, "i_id != {$oCurrent->i_id} AND i_order < {$i_order}");
