I have query with 6 columns and also I want to get the sum of other tables columns.
I want the result of sub query to be in one row but it repeated.
select t.id, t.subject, t.created_at, u.name, l.name as l_name,
ty.name as t_name
,(select sum(new) from statuses ) as new
,(select sum(open) from statuses) as open
,(select sum(close) from statuses) as close
,(select sum(`delete`) from statuses) as `delete`
from tickets t
left join users u on u.id=t.user_id
left join levels l on l.id=t.level_id
left join types ty on ty.id=t.type_id
could you please help me?
You can use GROUP BY in that,
select t.id, t.subject, t.created_at, u.name, l.name as l_name,
ty.name as t_name
,(select sum(new) from statuses ) as new
,(select sum(open) from statuses) as open
,(select sum(close) from statuses) as close
,(select sum(`delete`) from statuses) as `delete`
from tickets t
left join users u on u.id=t.user_id
left join levels l on l.id=t.level_id
left join types ty on ty.id=t.type_id GROUP BY u.name;

I have three tables, users(which includes user details), territory_categories(which has different territory names and their ids), user_territory(a junction table between the two)
I want to filter users based on selected territory from the list.
query for that is --
SELECT u.id,account_id_fk,first_name,last_name,email_address,password,mobile_number,gender,user_accuracy,check_in_radius,report_to,role,allow_timeout,
active,last_logged_on,last_known_location_time,last_known_location,u.created_on,u.created_by,
(SELECT COUNT(DISTINCT u2.id) FROM fieldsense.users u2
INNER JOIN user_territory t1 ON u2.id=t1.user_id_fk
INNER JOIN territory_categories c on c.id=t1.teritory_id
**WHERE c.category_name LIKE** "Gujarat" AND(u2.account_id_fk=1 AND u2.role!=0) ) AS usersCount,
IFNULL(a.id,0) attendanceId,IFNULL(a.punch_date,'1111-11-11') punchInDate,IFNULL(a.punch_in,0) punchIntime,IFNULL(a.punch_out_date,'1111-11-11') punchOutDate, IFNULL(a.punch_out,0) punchOutTime
FROM fieldsense.users as u
LEFT OUTER JOIN attendances as a ON u.id=a.user_id_fk AND a.id=(select max(id) from attendances att where att.user_id_fk=u.id)
INNER JOIN user_territory t1 ON u.id=t1.user_id_fk
INNER JOIN territory_categories c on c.id=t1.teritory_id
**WHERE c.category_name LIKE "Gujarat"**
GROUP BY u.id **limit 10**
OUTPUT :
usersCount: 136
attendanceId: 0
punchInDate: 1111-11-11
punchIntime: 0
punchOutDate: 1111-11-11
punchOutTime: 0
10 rows in set (2.06 sec)
And without where clause when it loads it takes almost 1 minute to display the data
OUTPUT without where clause :
usersCount: 144
attendanceId: 0
punchInDate: 1111-11-11
punchIntime: 0
punchOutDate: 1111-11-11
punchOutTime: 0
10 rows in set (54.45 sec)
I am getting the desired output, but query is taking almost 1 minute to load, which i want to optimize. how can i do this ?
Try this out. I just narrowed down your inner join on table user_territory, so it will not join whole user_territory table but will only join distinct user_ids in it. Hope it reduces the performance time,
SELECT u.id,
account_id_fk,
first_name,
last_name,
email_address,
PASSWORD,
mobile_number,
gender,
user_accuracy,
check_in_radius,
report_to,
role,
allow_timeout,
active,
last_logged_on,
last_known_location_time,
last_known_location,
u.created_on,
u.created_by,
(
SELECT
COUNT(u2.id)
FROM
fieldsense.users u2
INNER JOIN (SELECT DISTINCT user_id_fk as id, territory_id FROM user_territory ) t1 ON u2.id = t1.id
INNER JOIN territory_categories c ON c.id = t1.teritory_id
WHERE
c.category_name LIKE "Gujarat"
AND (
u2.account_id_fk = 1
AND u2.role != 0
)
) AS usersCount,
IFNULL(a.id, 0) attendanceId,
IFNULL(a.punch_date, '1111-11-11') punchInDate,
IFNULL(a.punch_in, 0) punchIntime,
IFNULL(
a.punch_out_date,
'1111-11-11'
) punchOutDate,
IFNULL(a.punch_out, 0) punchOutTime
FROM
fieldsense.users AS u
LEFT OUTER JOIN attendances AS a ON u.id = a.user_id_fk
AND a.id = (
SELECT
max(id)
FROM
attendances att
WHERE
att.user_id_fk = u.id
)
INNER JOIN (SELECT DISTINCT user_id_fk as id, territory_id FROM user_territory ) t1 ON u2.id = t1.id
INNER JOIN territory_categories c ON c.id = t1.teritory_id
WHERE
c.category_name LIKE "Gujarat"
GROUP BY
u.id
LIMIT 10
I have to do sum from 2 different tables and show it using MySQL:
total comments from table 1, total comments from table 2: What i have tried so far is,
SELECT u.name as name, u.username as username,
( SELECT SUM(total) FROM (SELECT (COUNT(nc.id)) as total FROM table1 as nc WHERE nc.user_id = u.id) UNION ALL (SELECT COUNT(pc.id) AS total FROM table2 pc WHERE pc.user_id = u.id) as finalTotal ) as total_comments
FROM user as u
GROUP BY u.id
It is giving me this error:
Every derived table must have its own alias
If I understand what you need, you have to modify the query like this :
select u.name,u.username,total as total_comments
from user as u
left join (
select id,sum(total) as total
from(
select nc.id,count(1) as total
from table1 as nc
group by nc.id
union all
select pc.id,count(1) as total
from table2 as pc
group by pc.id
) as t group by id
) comments on comments.id = u.id
Before UNION ALL put alias like you giving for all..
SELECT u.name as name, u.username as username,
( SELECT SUM(total) FROM (SELECT (COUNT(nc.id)) as total FROM table1 as nc WHERE nc.user_id = u.id) as vr UNION ALL (SELECT COUNT(pc.id) AS total FROM table2 pc WHERE pc.user_id = u.id) as finalTotal ) as total_comments
FROM user as u
GROUP BY u.id
SELECT u.name as name, u.username as username,
( SELECT SUM(total) FROM
(SELECT (COUNT(nc.id)) as total FROM table1 as nc WHERE nc.user_id = u.id
UNION ALL SELECT COUNT(pc.id) AS total FROM table2 pc WHERE pc.user_id = u.id) as finalTotal ) as total_comments
FROM user as u
GROUP BY u.id
Remove brackets before and after UNION ALL and check.
I spent so much time googling today but i don't even know which keywords to use. So …
The project is an evaluation of a betting game (Football). I have 2 SQL Queries:
SELECT players.username, players.userid, matchdays.userid, matchdays.points, SUM(points) AS gesamt
FROM players INNER JOIN matchdays ON players.userid = matchdays.userid AND matchdays.season_id=5
GROUP BY players.username
ORDER BY gesamt DESC
And my second query:
SELECT max(matchday) as lastmd, points, players.username from players INNER JOIN matchdays ON players.userid = matchdays.userid WHERE matchdays.season_id=5 AND matchday=
(select max(matchday) from matchdays)group by players.username ORDER BY points DESC
The first one adds up the points of every matchday and shows the sum.
The second shows the points of the last gameday.
My Goal is to merge those 2 queries/tables so that the output is a table like
Rank | Username | Points last gameday | Overall points |
I don't even know where to start or what to look for. Any help would be appreciated ;)
use both query with join....use inner join if each userid have value in 2nd query also.also add userid in 2nd query also for join
SET #rank = 0;
SELECT #rank := rank + 1,
t1.username,
t2.points,
t1.gesamt
FROM (
SELECT players.username, players.userid puserid, matchdays.userid muserid, matchdays.points, SUM(points) AS gesamt
FROM players INNER JOIN matchdays ON players.userid = matchdays.userid AND matchdays.season_id=5
GROUP BY players.username
)t1
INNER JOIN
(
SELECT players.userid, max(matchday) as lastmd, points, players.username
from players INNER JOIN matchdays ON players.userid = matchdays.userid
WHERE matchdays.season_id=5 AND matchday=
(select max(matchday) from matchdays)group by players.username
)t2
ON t1.puserid = t2.userid
ORDER BY t1.gesamt
You can use conditional aggregation, i.e. sum the points only when the day is the last day:
SELECT
p.username,
SUM(case when m.matchday = (select max(matchday) from matchdays) then m.points end)
AS last_day_points,
SUM(m.points) AS total_points
FROM players p
INNER JOIN matchdays m ON p.userid = m.userid AND m.season_id = 5
GROUP BY p.userid
ORDER BY total_points DESC;
Or with a join instead of a non-correlated subquery (MySQL should come to the same execution plan):
SELECT
p.username,
SUM(case when m.matchday = last_day.matchday then m.points end) AS last_day_points,
SUM(m.points) AS total_points
FROM players p
INNER JOIN matchdays m ON p.userid = m.userid AND m.season_id = 5
CROSS JOIN
(
select max(matchday) as matchday
from matchdays
) last_day
GROUP BY p.userid
ORDER BY total_points DESC;
Getting multiple records from table with subquery joins
SELECT
COUNT(*) AS total_count,
(SELECT
chat_box.user_id,
chat_box.message,
members.id,
members.display_name
FROM chat_box INNER JOIN members
ON chat_box.user_id = members.id
ORDER BY chat_id DESC LIMIT 1),
(SELECT COUNT(DISTINCT user_id) FROM chat_box) AS users_count
FROM chat_box
This is what I have so far, I want to get the members.display_name from the inner join where the chat_box.user_id = members.id as an output along aside the chat_box.message and save members.display_name and chat_box.message to a variable. Any help is appreciated.
It is not exactly clear what you are trying to do, but it seems like you could use something like this:
select u.user_id,
u.message,
u.id,
u.display_name,
cb1.total_count,
cb1.users_count
from
(
SELECT cb.user_id ,
cb.message,
m.id,
m.display_name
FROM chat_box cb
INNER JOIN members m
ON cb.user_id = m.id
) u
CROSS JOIN
(
select COUNT(*) AS total_count,
COUNT(DISTINCT user_id) AS users_count
FROM chat_box
) cb1
I have the following query, in which I used JOINs. It says:
unknown column m.bv ..
Could you please take a look and tell me what I'm doing wrong?
$query4 = 'SELECT u.*, SUM(c.ts) AS total_sum1, SUM(m.bv) AS total_sum
FROM users u
LEFT JOIN
(SELECT user_id ,SUM(points) AS ts FROM coupon GROUP BY user_id) c
ON u.user_id=c.user_id
LEFT JOIN
(SELECT user_id ,SUM(points) AS bv FROM matching GROUP BY user_id) r
ON u.user_id=m.user_id
where u.user_id="'.$_SESSION['user_name'].'"
GROUP BY u.user_id';
You are selecting SUM(points) AS bv from the table with the alias r, there is no tables with the alias m. So that it has to be r.bv instead like so:
SELECT
u.*,
SUM(c.ts) AS total_sum1,
SUM(r.bv) AS total_sum
FROM users u
LEFT JOIN
(
SELECT
user_id,
SUM(points) AS ts
FROM coupon
GROUP BY user_id
) c ON u.user_id=c.user_id
LEFT JOIN
(
SELECT
user_id,
SUM(points) AS bv
FROM matching
GROUP BY user_id
) r ON u.user_id = m.user_id
where u.user_id="'.$_SESSION['user_name'].'"
GROUP BY u.user_id
Replace m., with r. Look at second Join
You have aliased the derived table with r and you reference that table (twice) with m. Correct one or the other.
Since you group by user_id in the two subqueries and user_id is (I assume) the primary key of table user, you don't really need the final GROUP BY.
I would write it like this, if it was meant for all (many) users:
SELECT u.*, COALESCE(c.ts, 0) AS total_sum1, COALESCE(m.bv, 0) AS total_sum
FROM users u
LEFT JOIN
(SELECT user_id, SUM(points) AS ts FROM coupon GROUP BY user_id) c
ON u.user_id = c.user_id
LEFT JOIN
(SELECT user_id, SUM(points) AS bv FROM matching GROUP BY user_id) m
ON u.user_id = m.user_id
and like this in your (one user) case:
SELECT u.*, COALESCE(c.ts, 0) AS total_sum1, COALESCE(m.bv, 0) AS total_sum
FROM users u
LEFT JOIN
(SELECT SUM(points) AS ts FROM coupon
WHERE user_id = "'.$_SESSION['user_name'].'") c
ON TRUE
LEFT JOIN
(SELECT SUM(points) AS bv FROM matching
WHERE user_id = "'.$_SESSION['user_name'].'") m
ON TRUE
WHERE u.user_id = "'.$_SESSION['user_name'].'"
The last query can also be simplified to:
SELECT u.*,
COALESCE( (SELECT SUM(points) FROM coupon
WHERE user_id = u.user_id)
, 0) AS total_sum1,
COALESCE( (SELECT SUM(points) FROM matching
WHERE user_id = u.user_id)
, 0) AS total_sum
FROM users u
WHERE u.user_id = "'.$_SESSION['user_name'].'"
