我正在创建从多个表中选择数据的multipal select查询。我已经完成了所有的查询,但是现在我必须将GROUPBY应用到第二个select查询,但是GETTINGERROR is subquery返回超过1行。
group by in not working on suquery getting error is subquery返回超过1行。
我正在使用以下查询:
SELECT
( SELECT COUNT(bookings.user_id) as cleanings
FROM users INNER JOIN bookings
ON bookings.user_id = users.id
WHERE users.is_provider = 1
AND bookings.booking_status_id = 4 GROUP BY user.id) AS cleanings,
users.first_name,
users.last_name,
providerservicemaps.amount,
TRUNCATE(SUM(userreviews.rating)*5/(COUNT(userreviews.user_review_by)*5),
1) AS rating,
users.profilepic,
postcodes.postcode,
postcodes.suburb,
servicecategories.name,
provider_working_hours.start_time,
provider_working_hours.end_time
FROM users
INNER JOIN provider_working_hours
ON provider_working_hours.provider_id = users.id
INNER JOIN provider_postcode_maps
ON provider_postcode_maps.provider_id = users.id
INNER JOIN postcodes
ON postcodes.id = provider_postcode_maps.postcode_id
INNER JOIN providerservicemaps
ON providerservicemaps.provider_user_id = users.id
INNER JOIN userreviews
ON userreviews.user_review_for = users.id
INNER JOIN services
ON providerservicemaps.service_id = services.id
INNER JOIN servicecategories
ON services.category_id = servicecategories.id
INNER JOIN bookings
ON bookings.user_id = users.id
INNER JOIN bookingstatuses
ON bookings.booking_status_id = bookingstatuses.id
where users.is_provider=1
AND
postcodes.postcode LIKE '$postcode' AND postcodes.suburb LIKE
'$suburb'
AND servicecategories.name LIKE '$catagories'
AND FIND_IN_SET('$working_day',provider_working_hours.working_days)
AND provider_working_hours.start_time>='$start_time_result'AND provider_working_hours.end_time>='$end_time_result'
AND bookings.booking_time>='$start_time_result'
AND bookings.number_of_hours>='$work_hours'
GROUP BY users.first_name,
users.last_name,
providerservicemaps.amount,
userreviews.user_review_for,
users.profilepic,
postcodes.postcode,
postcodes.suburb,
servicecategories.name,
provider_working_hours.start_time,
provider_working_hours.end_time;

这是您的错误来源:
如果您想以列的形式返回某个内容,它必须是一个原子值。所以不能返回多行。
没有任何上下文,我可以给你一种方法,通过使用cte来消除错误。你必须决定是否保留逻辑。
另一种方法是对cleanings列使用相关子查询,如下所示:
