To fix the issue you can do I want to list companyIds and with the mostly occur commentable type (0,1,2). , You can do this using a having clause:
code :
SELECT a.companyId, a.commentable, COUNT(*) as _count
FROM article a
GROUP BY a.companyId, a.commentable
HAVING COUNT(*) = (SELECT COUNT(*)
                   FROM article a2
                   WHERE a2.companyId = a.companyId
                   GROUP BY a2.commentable
                   ORDER BY COUNT(*) DESC
                   LIMIT 1
                  );
SELECT a.companyId, a.commentable, COUNT(*) as _count
FROM article a
GROUP BY a.companyId, a.commentable
HAVING a.commentable = (SELECT a2.commentable
                        FROM article a2
                        WHERE a2.companyId = a.companyId
                        GROUP BY a2.commentable
                        ORDER BY COUNT(*) DESC
                        LIMIT 1
                       );

will be helpful for those in need The problem here is that when you are calling ToString the query is not executed yet, so essentially you are calling ToString on a IQueryable object, receiving the query instead of results. You need to call something to execute the query.
You can call ToList() still:
code :
var results = (from r in db.DownTimeCodes
              where r.Code == x
              select r.Description).ToList();
resultList.AddRange(results);
var results = (from r in db.DownTimeCodes
              where r.Code == x
              select r.Description).FirstOrDefault();
resultList.Add(results);

seems to work fine After a while, I figured out I can still use aggregation (https://docs.mongodb.com/manual/aggregation/) so here it comes:
code :
db.system.profile.aggregate([
    {
        $match: {
            "millis": {
                "$gt": 300
            },
            "op": "query"
        }
    },
    {
        $group: {
            "_id": {
                "collection": "$query.find",
                "command": "$command",
                "op": "$op"
            },
            "avgTime": {
                $avg: "$millis"
            },
            "count": {
                $sum: 1
            },
            "execStats": {
                $first: "$execStats"
            },
            "query": {
                $first: "$query"
            }
        }
    },
    {
        $sort: {
            "avgTime": -1
        }
    }
])

it helps some times I did a deep loop into class-wp-query.php and that's the natural behavior of pre_get_posts.
"Default" query parameters, like post type, default items_per_page... etc, are all set in a really complex "IF" sets., after the pre_get_posts actions.

I wish this helpful for you I have more tables, which I want to combine together for generate a CSV file what our backoffice system can read. I have 1 table with Product information and an other table with language information. The databases are build up as the following example: , You can join the name table multiple times with the Product table.
code :
select p.id, p.productnumber, p.price, en.name, it.name, de.name
from Product p
  join Name en on en.name_id=p.name_id and en.language_id=1
  join Name it on it.name_id=p.name_id and it.language_id=2
  join Name de on de.name_id=p.name_id and de.language_id=3
