Yii createCommand() return data set in different array format

Question

I'm a beginner in this framework. Though I have gone over the basics, there is one thing which is troubling me. As of now, I'm using

$group_sql = "SELECT uid FROM {$table}";
$group_users = Yii::app()->db->createCommand($group_sql)->queryAll();
print_r($group_users);

results in

Array
(
    [0] => Array
        (
            [uid] => 2
        )

    [1] => Array
        (
            [uid] => 3
        )

    [2] => Array
        (
            [uid] => 4
        )

    [3] => Array
        (
            [uid] => 5
        )

)

But I'd like to change the format in which the data is returned. What I'm looking for is something like

Array
(
    [0] => 2
    [1] => 3
    [2] => 4
    [3] => 5
)

OR

Array
(
    [uid] => Array
        (
            [0] => 2
            [1] => 3
            [2] => 4
            [3] => 5
        )
)

I'm aware that I can go through the documentation and get my answer, but due to time constraints, I'm taking the liberty to shamelessly ask this over here.

Thanks in advance.

Use queryColumn() method instead of queryAll()

If it's not much trouble, can you point me to the link where these methods have been documented so that I can go through them and see what other options I can use in future?
