I am having trouble executing this sql. I need to get the result and send it via JSON to my web page.

I am getting this error:

I need to filter by null priority but the generated query has priority on the outer query if required:false which is logically wrong and the only way that I found to put the priority inside the subquery is to use required:true but this results in an inner join and I want left join in order to take the null values. Is there a way to force the include as left join inside the subquery?The nested subquery is generated because it exists a many to many relationship between Orders and Employees and limit must be applied to orders. I want to generate the following Query:
`Orders` .*,
`OrderPriority`.`id` as `OrderPriority.ID`,
`OrderPriority`.`priority` as `OrderPriority.priority`,
`Employees`.`employee_alias` as `Employees.alias`,
`Employees`.`employee_id` as `Employees.ID` from

I have this query and it take 117 seconds to get 100000 rows can me get all this rows on 5 seconds or 10 seconds?

AND im.type ='1'

I am getting all the desired results except for the sub select query.. each hotel has a price but it is only giving me back one result and the rest are all null. Is there an error in my query? If any additional information is needed please let me know and thank you in advance for any help!
You are missing the GROUP BY in your subquery, so MySQL will only return one-value. If you want all hotel_id's then you need to GROUP BY that field:
SELECT GROUP_CONCAT(DISTINCT(ca.category_name) SEPARATOR ', ') AS categories,
pr.promo_name,
pr.add_value_text,
c.contract_id,
c.cmeal_plan,
c.cmin_markup,
c.civa,
c.tax_include,
c.hotel_id,
hi.hname,
hi.hstars,
im.image_file,
pl.plan_name,
ra.price
FROM contracts AS c
INNER JOIN hotel_info AS hi
ON hi.hotel_id = c.hotel_id
AND hi.destination_id = '6460'
INNER JOIN images AS im
ON im.foreign_id = hi.hotel_id
INNER JOIN meal_plan AS pl

INNER JOIN hotel_categories AS hc
ON hc.hotel_id = hi.hotel_id
INNER JOIN categories AS ca
ON ca.category_code = hc.category_code
AND ca.lang = '1'
LEFT JOIN
(
SELECT r.hotel_id, AVG(r.double) AS price
FROM rates AS r
GROUP BY r.hotel_id <-- add a GROUP BY hotel_id then you will get avg() for each hotel
) AS ra
ON ra.hotel_id = hi.hotel_id
LEFT JOIN promotions AS pr
ON pr.hotel_id = hi.hotel_id
AND FIND_IN_SET(c.contract_id, pr.contract_id) > 0

Query takes 0.4s~ to run. It's because of subquery in WHERE statement:
v.video_id IN (
SELECT gc2.parent_id
FROM tags_relations gc2
WHERE gc2.tag_id IN(14) AND gc2.department=18
GROUP BY gc2.parent_id
HAVING COUNT(gc2.parent_id)=1
)
Without it, it runs 0.07s~
Maybe try something with advanced joins? shy
Thanks ;)
In MySQL, never use WHERE in (SELECT ... it is notoriously slow.
Use a join instead:

Edit:
I took a closer look at your query and think it can be reduced to the following:
SELECT `v1`.*
, GROUP_CONCAT(DISTINCT(`gg`.genre_id)) AS `genre_ids`
, GROUP_CONCAT(DISTINCT(`gg`.genre_ru)) AS `genres`
, GROUP_CONCAT(DISTINCT(`tg`.tag_id)) AS `tags_ids`
, GROUP_CONCAT(DISTINCT(`tg`.name)) AS `tags`
FROM (
SELECT v.*
FROM `video` AS `v`
LEFT JOIN `video_categories` AS `gc` ON gc.video_id = v.video_id
LEFT JOIN `tags_relations` AS `tr` ON tr.parent_id = v.video_id
WHERE gc.genre_id IN(44)
AND tr.tag_id IN(14)
AND tr.department=18
GROUP BY `v`.`video_id`
HAVING COUNT(*) = 1
) v1
LEFT JOIN `video_genres` AS `gg` ON gg.genre_id = gc.genre_id
LEFT JOIN `tags` AS `tg` ON tg.tag_id = tr.tag_id
