fetch data with activerecord in FETCH_KEY_PAIR array format

I have table like this:

CREATE TABLE `developer` (

  `id` bigint(20) AUTO_INCREMENT,

  `name` varchar(1024) NOT NULL,

  `link` varchar(1024) NOT NULL,

  `parent` bigint(20) DEFAULT NULL,

  PRIMARY KEY (`id`),

  KEY `parent` (`parent`),

  CONSTRAINT `developer_ibfk_1` FOREIGN KEY (`parent`) REFERENCES `developer` (`id`) ON DELETE SET NULL ON UPDATE CASCADE

) ENGINE=InnoDB CHARSET=utf8 COLLATE=utf8_unicode_ci;

I want get only id,name in PDO::FETCH_KEY_PAIR array from this table and use:

Developer::find()->select(['id', 'name'])->asArray()->all();

But I can not get the data in PDO::FETCH_KEY_PAIR format

how can i do it?

By any chance, are you looking for indexBy()?

thank you for replay

i want get records like this:

array (size=6)

1 => string ‘google’ (length=6)

2 => string ‘ubuntu’ (length=6)

4 => string ‘apple’ (length=5)

5 => string ‘adobe’ (length=5)

9 => string ‘microsoft’ (length=9)

if i want do this with php write:

$pdo = new PDO('mysql:host=localhost;dbname=db', 'root', '');

$sql = 'SELECT id,name FROM developer';

$q = $pdo->query($sql);




but i want do this with activerecord.

I know that I can use the array helper or write function to do this

but i want know is there an option to set this property($q->setFetchMode(PDO::FETCH_KEY_PAIR)).

There probably is through \Yii::$app->db->pdo. I’d advise against it, though.

i use

\yii::$app->db->pdo->setAttribute(\PDO::ATTR_DEFAULT_FETCH_MODE, \PDO::FETCH_KEY_PAIR);

and get this error:

Call to a member function setAttribute() on a non-object

can you give me a example by code?

Hm, I suspect the PDO object hasn’t been loaded at that point. You can try opening the connection up by calling [font=“Courier New”]\Yii::$app->db->open()[/font] first. Alternatively try setting that flag through the attributes in your db config.
