Strange behaviours with conditions (WHERE int) in CActiveDataProvider

Hi everybody,

I am new to Yii and so to the Forum. But I need your help to understand a really esoteric behaviour…

We have a Database with a field ‘status’. Status is an int and can be from 0 to 10. I created some scopes to get the data I want:

public function scopes()


        return array(

            'latestProjects'	=> array(

                'order'	=> 'date DESC',

		'condition'	=> "status = '5'"


	    'groupInternal'		=> array(

		'group'	=> 'internalProjectID'




(of course, the status condition will be a parameterized scope, but it doesn’t matter for the tests…)

Then I call

$proposalData	= new CActiveDataProvider(Project::model()->latestProjects()->groupInternal(), array());

It works fine when status is > 5 (6, 7, etc.), but any status beyond 5 gets me a


CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') GROUP BY internalProjectID) sq' at line 1. The SQL statement executed was: SELECT COUNT(*) FROM (SELECT * FROM `tw_project` `t` WHERE (status = '5') AND () GROUP BY internalProjectID) sq 

Exception… and we don’t know why. The query can’t be wrong, because with status = 6 (or status < 6 oder status <= 6) it works fine…

Can anybody help?

Thanks in advance!

It is said the error is

it means first of all you should look at the beginning of the error part in your query:

WHERE (status = ‘5’) AND () GROUP

This empty AND gives you the error. It’s not clear from provided code which way exactly one more additional condition (empty one) is added to your query, so just try to find it.
