By default, if you have a hasOne or belongsTo relationship between models, CakePHP will build a JOIN query using LEFT JOIN. In some cases, however, you would really prefer to do an INNER JOIN instead.

This is easily accomplished by specifying the ‘type’ key in your association.

So, for example, User hasOne Post:

var $hasOne = array(‘Post’=>array(‘type’=>’INNER’));

That’s all. Cake will now build a query using the INNER JOIN.

Remember that this key only works in the hasOne or belongsTo associations. If you would like to know how to force CakePHP to do JOIN for other types of associations, please take a look at this post.
