use yii\mongodb\Query;

$users = array_keys((new Query())->from('tbl_user')->select(['userid'])->indexBy('userid')->all());

//the result of $users is [1,2,3]

$rzt= $query->from('tbl_log')->where(['in','userid',$users])->count();

//the  result of $rzt is 10

but…I got 0 by the flowing code:


  


$users = (new Query())->from('tbl_user')->select(['userid']);

$rzt = $query->from('tbl_log')->where(['in','userid',$users])->count();

How to use the ‘in’ condition ?
