Laravel Eloquent Query With OR WHERE Condition - laravel

Question

I am using Laravel 6 & mysql 7
I have below query
$tasks = Task::where('deleted_at', null)->where('company_id',$company_id);
$tasks = $tasks->where('created_by',$user_id);
$tasks = $tasks->orWhereIn('id',$task_ids);
It generates below raw query when i print it
SELECT * FROM `tasks` WHERE `deleted_at` IS NULL AND `company_id` = 25 AND `created_by` = 20 OR
`id` IN(112,...215) ORDER BY `id` DESC
Now Id 112 is deleted but still showing in result, although i have where('deleted_at', null) condition but it is not working
I want to apply all other conditions on $task_ids as well
How this can be achieved with optimized query?
UPDATED: Here is complete scenario
I want to select all records which is created by me or assigned to me. Here is my complete code.
$tasks = Task::where('deleted_at', null)->where('company_id',$company_id);
$tasks = $tasks->where('created_by',$user_id);
$task_ids = TaskUser::where('user_id',$user_id)->pluck('task_id')->all();
$tasks = $tasks->orWhereIn('id',$task_ids);

This is because the AND operator has a higher precedence than OR, which basically means that AND "sticks" together more than OR does. You query basically is interpredeted like this:
SELECT * FROM `tasks`
WHERE
(`deleted_at` IS NULL AND `company_id` = 25 AND `created_by` = 20)
OR
( `id` IN(112,...215) )
I am not entirly sure wheter you actually want to OR anything. If you really want to apply all conditions, you just need to change the orWhereIn to a whereIn.
In case you want all not-deleted tasks, that EITHER belong to a company and a auser OR whose id is in the list, you would need to update your query like this:
$tasks = Task::where('deleted_at', null);
$tasks = $tasks->where(function($q) use ($user_id, $task_ids){
$q->where(function($q2) use ($user_id, $task_ids) {
$q2->where('created_by',$user_id)
->where('company_id',$company_id);
})
->orWhereIn('id',$task_ids);
});
which should result in this query:
SELECT * FROM `tasks`
WHERE `deleted_at` IS NULL AND (
( `company_id` = 25 AND `created_by` = 20 )
OR
`id` IN(112,...215)
)
There is actually a chapter about parameter grouping in the excellent laravel documentation as well.
