Mysql 无效参数编号：绑定变量的数量与令牌的数量不匹配

数据显示正确，但当我尝试在过滤器中搜索时；它伴随着错误而来

 $dataProvider=$model->search();

 $dataProvider->criteria->addcondition('company_code= :id')->params=array(':id' => $company);

 $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'tblapptcodegrid',
'dataProvider'=>$dataProvider,
'filter'=>$model,

有人能解释一下原因吗？

试试看

CDbCommand failed to execute the SQL statement: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens. The SQL statement executed was: SELECT COUNT(*) FROM `tblapptcode` `t` WHERE (appt_code LIKE :ycp0) AND (company_code= :id) (C:\wamp\www\yii\framework\db\CDbCommand.php:543)

试一试

你能不能给出一个理由，说明为什么这个和那个有问题的相反。。

$dataProvider->criteria->addcondition('company_code= :id')->params[':id'] = $company;
