根据id查询一条数据,并对id进行过滤:
$id = 1; $result = Yii::$app->db->createCommand("select * from product where id=:id")->bindParam(":id",$id,\PDO::PARAM_INT)->queryAll(); $result = Yii::$app->db->createCommand("select * from product where id=:id")->bindParam(":id",$id,\PDO::PARAM_STR)->queryAll();
更新一条数据:
$id = 1; $name = 'xiaoming'; $result = Yii::$app->db->createCommand("update product set name=:name where id=:id")-> bindParam(':id',$id,\PDO::PARAM_INT)->bindParam(':name',$name,\PDO::PARAM_INT)->execute();
以下写法在会报错
$result = Yii::$app->db->createCommand()->delete('product', ['name'=>':value'],'id=:id')->bindValue(':id',1,\PDO::PARAM_INT)-> bindParam(':value',$user,\PDO::PARAM_INT)->execute();
