Question

Yii

Good afternoon. Let's assume there is a table
id title subtitle description
1 11 14 17
2 12 15 18
3 13 16 19
How would a select query in Yii look like if you need to pick up all the values ​​of the description field, i.e.
you need to pick up 17,18,19. Thanks in advance)

Answer 1

Model::find()->select(['description'])->all();

Answer 2

Option Andrey Tokmakov selects all "description". Here is an option that will select everything where description is 17 or 18 or 19:

$arr = [17,18,19];
$model = Model::find()->where(['description'=>$arr])->all();
