mysql - 选择在 Yii CDbCriteria 中不起作用

Question

我有两个相关表，我必须通过连接查询显示来自两个表的数据。我有这个 GridView，当我必须进行搜索时它正在“工作”，这意味着如果我必须从连接表中搜索一个字段，它会工作并显示正确的结果，但我我无法显示两个表中的所有列。

这里是错误:

CDbCommand failed to execute the SQL statement: SQLSTATE[42S02]: Base table or view not found: 1051 Unknown table 'pratiche'. The SQL statement executed was: SELECT pratiche.* FROM pratiche t LEFT JOIN clienti ON id_cliente = clienti.id LIMIT 10

如您所见，pratiche 后面有t，因此查询失败。有什么问题？

public function search()
{
    // @todo Please modify the following code to remove attributes that should not be searched.

    $criteria=new CDbCriteria;

    $criteria->select = "pratiche.*,clienti.*";

    $criteria->join='LEFT JOIN clienti ON id_cliente = clienti.id';

    $criteria->compare('id_pratiche',$this->id_pratiche,true);
    //this is the fild that should be shown(from the joined table)
    $criteria->compare('codice_fiscale',$this->codice_fiscale,true);

    $criteria->select = "pratiche.*";
    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

解决了!设置条件的错误方法:

$criteria->select=array('id_pratiche','data_creazione','stato_pratica','nome','cognome');
