Convert from query to ModelSearch of Yii2 - php

Question

I'm new in Yii2, and I have a query with right result:
SELECT DISTINCT workloadTeam.project_id, wp.project_name, workloadTeam.user_id, workloadTeam.commit_time, wp.workload_type FROM
(SELECT p.id, p.project_name, w.user_id, w.commit_time, w.comment, w.workload_type
FROM workload as w, project as p
WHERE w.user_id = 23 AND p.id = w.project_id) wp
INNER JOIN workload as workloadTeam ON wp.id = workloadTeam.project_id
But in my ModelSearch.php, I wrote:
$user_id = Yii::$app->user->id;
$subquery = Workload::find()->select('p.id', 'p.project_name', 'w.user_id', 'w.commit_time', 'w.comment', 'w.workload_type')
->from(['project as p', 'workload as w'])
->where(['user_id' => $user_id, 'p.id' => 'w.project_id']);
$query = Workload::find()
->select(['workloadTeam.project_id', 'wp.project_name', 'workloadTeam.user_id', 'workloadTeam.from_date', 'workloadTeam.to_date', 'workloadTeam.workload_type', 'workloadTeam.comment'])
->where(['', '', $subquery]);
$query->join('INNER JOIN', 'workload as workloadTeam', 'wp.id = workloadTeam.project_id');
It happended error:
SELECT COUNT(*) FROM `workload` INNER JOIN `workload` `workloadTeam` ON wp.id = workloadTeam.project_id WHERE `` (SELECT p.project_name `p`.`id` FROM `project` `p`, `workload` `w` WHERE (`user_id`=20) AND (`p`.`id`='w.project_id'))
And I can't fix it with right query above.
You have any solution about this?

Answer 1

Is this error shown in the Yii-debug toolbar? Then your query (which you mentioned as error) is probably only the count from the query which is listed before.
You missed to add the sub-query in from clause like you shown in your working sql. Add this in your where clause were just the wrong place. Put sub-queries in whereconditions, if you have scalar results, because you have to use this result with operands like =, >=, in...
This could work:
$user_id = Yii::$app->user->id;
$subquery = Workload::find()->select([
'p.id as id',
'p.project_name as project_name',
'w.user_id as user_id',
'w.commit_time as commit_time',
'w.comment as comment',
'w.workload_type as workload_type'
])
->from([
'project as p',
'workload as w'
])
->where([
'user_id' => $user_id,
'p.id' => 'w.project_id'
]);
$query = Workload::find()
->select([
'workloadTeam.project_id',
'wp.project_name',
'workloadTeam.user_id',
'workloadTeam.from_date',
'workloadTeam.to_date',
'workloadTeam.workload_type',
'workloadTeam.comment'
])
->from([$subquery => 'wp']); //you were missing this line
$query->join('INNER JOIN', 'workload as workloadTeam', 'wp.id = workloadTeam.project_id');
But you don't use any selects from your workload table in your main-query $query...
Since I don't know what's your goal to achieve I can't help you at this topic...
