Hi there,

I’m new with Yii and I’m trying to learn it.

I’ve a problem with relations transaction_stat as defined below.

	public function relations()


		// NOTE: you may need to adjust the relation name and the related

		// class name for the relations automatically generated below.

		return array(

			'address' => array(self::HAS_MANY, 'Address', 'userFK'),

			'transaction' => array(self::HAS_MANY, 'Transaction', 'userFK'),

			'transaction_stat' => array(self::STAT, 'Transaction', 'userFK',

				'select' => 'SUM(importo) as fatturato, count(*) as transazioni, MAX(data) as ultimo_acquisto',




This relations give me an exception because Yii create the query in this way:

SELECT userFK AS c, SUM(importo) as fatturato, count(*) as transazioni, MAX(data) as ultimo_acquisto AS s

So it add an AS s at my last element that broke the query.

If I try so set relation in this way as explained in CActiveRecord api page

(Additional options may be specified as name-value pairs in the rest array elements:

‘select’: string|array, a list of columns to be selected):

				'select' => array('SUM(importo) as fatturato', 'count(*) as transazioni', 'MAX(data) as ultimo_acquisto'),

I’ve this exception “Column not found: 1054 Unknown column ‘Array’ in ‘field list’. The SQL statement executed was: SELECT userFK AS c, Array AS s FROM”

At the moment i’m not able to solve this.

Could someone help me?

Thanks in advance

Have the same problem. Looking at source code, select really converted to array, if it not equal ‘*’.


maybe you could try to specify your relation in 3, one relation for field (sum, count and max).
