How to get the last value of a field from a model?

Question

Yii

there is a model, a table (as you like), here is the name of the fields -
'id','name','id_operation'
idautoincrement
id_operation- can be the same for several records.
I need to get the last value id_operation, given that the numbering is ascending from zero.

Answer 1

I need to get the last value of id_operation, given that the numbering is ascending from zero.

then your last value will be the maximum. If you need to get only the field value, use
if you need to get all the model data - use the option suggested by Maxim Timofeev

Answer 2

$model = Model::find()->orderBy('id_operation DESC')->one();
echo $model->id_operation;

Or did I misunderstand?
