|
|
* With this extension, you can create sql strings for use on where parameter of select method from Webmodel.
|
|
*
|
|
* Example ['AND']->array( 'field' => array('!=', 25), 'field2' => array('=', 'value_field'), 'field3' => array('LIKE', 'value_field'), 'field4' => array('IN', array('1','2','3'), 'limit_sql' => array('LIMIT', array(1, 10), 'order_by' => array('order_fieldY', 'ASC'
|
|
))
|
|
*
|
|
* You can join differents sql sentences
|

|
* @warning Experimental, don't use in production
