really do not know if you can, but i I need the DATE VENC to be equal to '2013-02-02'.
the values of the column date_pay:
1-2013-01-01
2-2013-02-02
3-0000-00-00
4-0000-00-00
this is my query:
SELECT s.id,
s.name,
s.nro_s,
ts.cat,
SUM( ts.pryce ) AS deuda,
SUM( ts.pryce ) DIV ts.pryce AS c_p,
date_venc = (select max(date_pay) from c ) // the date in question
FROM s
INNER JOIN c
INNER JOIN ts
WHERE s.id = '123'
AND c.id = '123'
AND c.date_pay = '0000-00-00'
AND s.ts = ts.id_ts
Sorry for my english, is very basic.
Greetings.
Assuming date_venc is DATE a possible solution
select *
from s
where s.date_venc=
(select max(cast(SUBSTRING_INDEX(date_pay,'-',-3)as DATE))from c);
also check out sqlfiddle
http://sqlfiddle.com/#!2/64197/1
and your query should probably be modified to,
SELECT s.id,
s.name,
s.nro_s,
ts.cat,
SUM( ts.pryce ) AS deuda,
SUM( ts.pryce ) DIV ts.pryce AS c_p,
date_venc
FROM s
INNER JOIN c
INNER JOIN ts
WHERE s.id = '123'
AND c.id = '123'
AND c.date_pay = '0000-00-00'
AND s.ts = ts.id_ts
AND date_venc = (select max(cast(SUBSTRING_INDEX(date_pay,'-',-3)as DATE)) from c ) // the date in question

I have the next SQL statement:
SELECT
p.ID,
p.TheName0,
(SELECT IFNULL(SUM(att.S_FinalAmount),0) From tbl_groups_classes_att att
INNER JOIN tbl_students st
ON st.ID = att.StudentID

ON cls.ID = att.ClassID
WHERE st.ParentID = p.ID
and cls.TheDate BETWEEN #Date1 and #Date2
and att.TheStatus <> 'absent'
) as CurrMost,
(SELECT IFNULL(SUM(att.S_FinalAmount),0) From tbl_groups_classes_att att

(SELECT IFNULL(SUM(pay.TheAmount),0) From tbl_parents_payments pay Where p.ID = pay.ParentID
AND pay.TheDate BETWEEN #Date1 and #Date2

(SELECT IFNULL(SUM(pay.TheAmount),0) From tbl_parents_payments pay Where p.ID = pay.ParentID

) as PrevMadf,
(SELECT CurrMost + PrevMost) as AllMost,
(SELECT CurrMadf + PrevMadf) as AllMadf,
(SELECT AllMost - AllMadf) AS FinalTotal
from tbl_parents p
I want to order it by FinalTotal, I tried to put :
from tbl_parents p order by FinalTotal
but it doesn't be affected.
how I can sort it? and please note that I tried many solutions on the internet but without result.
thanks advanced
The fail-safe solution is to place the whole query as a table expression to produce the column name, and then sorting is trivial.
For example:
select *
from (
-- your query here
) x
order by FinalTotal
I'm not sure how to make the following SQL query more efficient. Right now, the query is taking 8 - 12 seconds on a pretty fast server, but that's not close to fast enough for a Website when users are trying to load a page with this code on it. It's looking through tables with many rows, for instance the "Post" table has 717,873 rows. Basically, the query lists all Posts related to what the user is following (newest to oldest).
Is there a way to make it faster by only getting the last 20 results total based on PostTimeOrder?
Any help would be much appreciated or insight on anything that can be done to improve this situation. Thank you.
Here's the full SQL query (lots of nesting):
SELECT DISTINCT p.Id, UNIX_TIMESTAMP(p.PostCreationTime) AS PostCreationTime, p.Content AS Content, p.Bu AS Bu, p.Se AS Se, UNIX_TIMESTAMP(p.PostCreationTime) AS PostTimeOrder
FROM Post p
WHERE (p.Id IN (SELECT pc.PostId
FROM PostCreator pc
WHERE (pc.UserId IN (SELECT uf.FollowedId
FROM UserFollowing uf
WHERE uf.FollowingId = '100')
OR pc.UserId = '100')
))
OR (p.Id IN (SELECT pum.PostId
FROM PostUserMentions pum
WHERE (pum.UserId IN (SELECT uf.FollowedId
FROM UserFollowing uf
WHERE uf.FollowingId = '100')
OR pum.UserId = '100')
))
OR (p.Id IN (SELECT ssp.PostId
FROM SStreamPost ssp
WHERE (ssp.SStreamId IN (SELECT ssf.SStreamId
FROM SStreamFollowing ssf
WHERE ssf.UserId = '100'))
))
OR (p.Id IN (SELECT psm.PostId
FROM PostSMentions psm
WHERE (psm.StockId IN (SELECT sf.StockId
FROM StockFollowing sf
WHERE sf.UserId = '100' ))
))
UNION ALL
SELECT DISTINCT p.Id AS Id, UNIX_TIMESTAMP(p.PostCreationTime) AS PostCreationTime, p.Content AS Content, p.Bu AS Bu, p.Se AS Se, UNIX_TIMESTAMP(upe.PostEchoTime) AS PostTimeOrder
FROM Post p
INNER JOIN UserPostE upe
on p.Id = upe.PostId
INNER JOIN UserFollowing uf
on (upe.UserId = uf.FollowedId AND (uf.FollowingId = '100' OR upe.UserId = '100'))
ORDER BY PostTimeOrder DESC;
Changing your p.ID in (...) predicates to existence predicates with correlated subqueries may help. Also since both halves of your union all query are pulling from the Post table and possibly returning nearly identical records you might be able to combine the two into one query by left outer joining to UserPostE and adding upe.PostID is not null as an OR condition in the WHERE clause. UserFollowing will still inner join to UPE. If you want the same Post record twice once with upe.PostEchoTime and once with p.PostCreationTime as the PostTimeOrder you'll need keep the UNION ALL
SELECT
DISTINCT -- <<=- May not be needed
p.Id
, UNIX_TIMESTAMP(p.PostCreationTime) AS PostCreationTime
, p.Content AS Content
, p.Bu AS Bu
, p.Se AS Se
, UNIX_TIMESTAMP(coalesce( upe.PostEchoTime
, p.PostCreationTime)) AS PostTimeOrder
FROM Post p
LEFT JOIN UserPostE upe
INNER JOIN UserFollowing uf
on (upe.UserId = uf.FollowedId AND
(uf.FollowingId = '100' OR
upe.UserId = '100'))
on p.Id = upe.PostId
WHERE upe.PostID is not null
or exists (SELECT 1
FROM PostCreator pc
WHERE pc.PostId = p.ID
and pc.UserId = '100'
or exists (SELECT 1
FROM UserFollowing uf
WHERE uf.FollowedId = pc.UserID
and uf.FollowingId = '100')
)
OR exists (SELECT 1
FROM PostUserMentions pum
WHERE pum.PostId = p.ID
and pum.UserId = '100'
or exists (SELECT 1
FROM UserFollowing uf
WHERE uf.FollowedId = pum.UserId
and uf.FollowingId = '100')
)
OR exists (SELECT 1
FROM SStreamPost ssp
WHERE ssp.PostId = p.ID
and exists (SELECT 1
FROM SStreamFollowing ssf
WHERE ssf.SStreamId = ssp.SStreamId
and ssf.UserId = '100')
)
OR exists (SELECT 1
FROM PostSMentions psm
WHERE psm.PostId = p.ID
and exists (SELECT
FROM StockFollowing sf
WHERE sf.StockId = psm.StockId
and sf.UserId = '100' )
)
ORDER BY PostTimeOrder DESC
The from section could alternatively be rewritten to also use an existence clause with a correlated sub query:
FROM Post p
LEFT JOIN UserPostE upe
on p.Id = upe.PostId
and ( upe.UserId = '100'
or exists (select 1
from UserFollowing uf
where uf.FollwedID = upe.UserID
and uf.FollowingId = '100'))
Turn IN ( SELECT ... ) into a JOIN .. ON ... (see below)
Turn OR into UNION (see below)
Some the tables are many:many mappings? Such as SStreamFollowing? Follow the tips in http://mysql.rjweb.org/doc.php/index_cookbook_mysql#many_to_many_mapping_table
Example of IN:
SELECT ssp.PostId
FROM SStreamPost ssp
WHERE (ssp.SStreamId IN (
SELECT ssf.SStreamId
FROM SStreamFollowing ssf
WHERE ssf.UserId = '100' ))
-->
SELECT ssp.PostId
FROM SStreamPost ssp
JOIN SStreamFollowing ssf ON ssp.SStreamId = ssf.SStreamId
WHERE ssf.UserId = '100'
The big WHERE with all the INs becomes something like
JOIN ( ( SELECT pc.PostId AS id ... )
UNION ( SELECT pum.PostId ... )
UNION ( SELECT ssp.PostId ... )
UNION ( SELECT psm.PostId ... ) )
Get what you can done of that those suggestions, then come back for more advice if you still need it. And bring SHOW CREATE TABLE with you.
In the following query I'm having a problem when it comes to returning the right value for count2.
What I need is to get the number of rows from table2 which could easily be done by using a derived table t:
SELECT name,
(SELECT COUNT(*) FROM `table1`) AS count1,
(SELECT COUNT(*) FROM (
SELECT COUNT(*) FROM `table2` t2) WHERE t2.user = prf.user)
) t AS count2,
(SELECT SUM(a) FROM `table3`) AS count3
FROM `profiles` prf
WHERE 1=1
AND prf.user = 1
The problem is that the WHERE t2.user = prf.user statement fails as the prf table is outside the subquery's scope.
How can I achieve the above?
EDIT: I'm adding the actual query in case it's helpful for getting a better grasp:
SELECT PRF.BranchID, PRF.user_id, CONCAT_WS(" ",PRF.lastname,PRF.firstname) Synergatis,
( SELECT COUNT(*) FROM Actions A JOIN Requests R ON R.RequestID=A.RequestID WHERE A.ActionStatus = 302 AND A.UserOwner = PRF.user_id AND A.ActionDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS energeies,
( SELECT COUNT(DISTINCT RPP.RequestID) FROM VW_Xartofylakio_Synergati VV JOIN Requests_Prop RPP ON RPP.PropertyID = VV.PropertyID JOIN Requests R ON R.RequestID = RPP.RequestID WHERE VV.CurrUsr = PRF.user_id AND R.ModifyTime BETWEEN '2015-06-01' AND '2015-06-10' ) AS zitiseis_eidikes,
( SELECT COUNT(DISTINCT(CustomerID)) FROM Demo_Orders_M WHERE DemoOrderStatus=253 AND USER=PRF.user_id AND DemoOrderDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS endiaferomenoi,
( SELECT COUNT(*) AS cnt FROM Demo_Orders_M DOM JOIN Actions A ON DOM.DemoOrderID = A.DemoOrderID WHERE DOM.User = PRF.user_id AND DOM.DemoOrderStatus = 253 AND A.ActionDate BETWEEN '2015-06-01 14:56:19' AND '2015-06-30 14:56:19' GROUP BY DOM.CustomerID, DOM.User HAVING COUNT(*) > 1 ) AS anakykl_endiaf,
( SELECT COUNT(*) FROM Demo_Orders_M DOM WHERE DOM.`User`=PRF.user_id AND DemoOrderStatus = 253 AND DOM.DemoOrderDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS epideixeis,
( SELECT COUNT(DISTINCT(DOD.PropertyID)) AS PropertyID FROM Demo_Orders_M DOM JOIN Demo_Orders_D DOD ON DOM.DemoOrderID = DOD.DemoOrderID JOIN Actions A ON DOD.DemoOrderID = A.DemoOrderID WHERE DOM.DemoOrderStatus = 253 AND DOM.User = PRF.user_id AND A.ActionDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS monadika_akinita
FROM tbl_profiles PRF
WHERE 1=1
AND PRF.user_id IN (
SELECT a.user_id FROM tbl_profiles a WHERE a.user_id IN ('248','1159','486','183')
OR a.GroupID IN (SELECT b.GroupID FROM L_Groups b WHERE b.ManagerID IN ('248','1159','486','183'))
)
ORDER BY PRF.user_id
The subquery I'm referring to is the one that returns the result as anakykl_endiaf.
I suspect it is not because of prf table, it is because of t2 table... There are no restrictions to use outer alias in inner subqueries because there are such a thing like correlated subquery. Your problem is that you have the opposite case here: you are referring inner alias in outer query.
(SELECT COUNT(*)
FROM (SELECT COUNT(*) FROM `table2` t2) WHERE t2.user = prf.user)
Why are you selecting count twice here? You can change to this:
(SELECT COUNT(*)
FROM (SELECT COUNT(*) FROM `table2` t2 WHERE t2.user = prf.user))
or this:
(SELECT COUNT(*)
FROM `table2` t2 WHERE t2.user = prf.user)
A suggestion to try.
You have sub queries in the SELECT, and in this case they must each only return a single row. For some reason (which we can't really tell without test data) one of these is returning more than 1 row, hence failing.
As an interim step, change the query to join against the sub queries, which should make it more obvious when there are duplicates (and may also be quite a bit more efficient, depending on the data).
Something like this (not tested so probably a few typos):-

If you just want a count of the number of customerID fields for a user in the anakykl_endiaf field then change it to doing a count of distinct customerIDs. Ie, for the above query I have done change it to:-
LEFT OUTER JOIN

SELECT DOM.`User` AS DomUser, COUNT(DISTINCT DOM.CustomerID) AS anakykl_endiaf

Here's the query:
SELECT h.idhour, h.`hour`, outnumber, count(*) as `count`, sum(talktime) as `duration`
FROM (
SELECT
`cdrs`.`dcustomer` AS `dcustomer`,
(CASE
WHEN (`cdrs`.`cnumber` like "02%") THEN '02'
WHEN (`cdrs`.`cnumber` like "05%") THEN '05'
END) AS `outnumber`,
FROM_UNIXTIME(`cdrs`.`start`) AS `start`,
(`cdrs`.`end` - `cdrs`.`start`) AS `duration`,
`cdrs`.`talktime` AS `talktime`
FROM `cdrs`
WHERE `cdrs`.`start` >= #_START and `cdrs`.`start` < #_END
AND `cdrs`.`dtype` = _LATIN1'external'
GROUP BY callid
) cdr
JOIN customers c ON c.id = cdr.dcustomer
LEFT JOIN hub.hours h ON HOUR(cdr.`start`) = h.idhour
WHERE (c.parent = _ID or cdr.dcustomer = _ID or c.parent IN
(SELECT id FROM customers WHERE parent = _ID))
GROUP BY h.idhour, cdr.outnumber
ORDER BY h.idhour;
The above query results skips the hours where there is no data, but I need to show all hours (00:00 to 23:00) with null or 0 values. How can I do this?
SELECT h.idhour
, h.hour
,IFNULL(outnumber,'') AS outnumber
,IFNULL(cdr2.duration,0) AS duration
,IFNULL(output_count,0) AS output_count
FROM hub.hours h
LEFT JOIN (
SELECT HOUR(start) AS start,outnumber, SUM(talktime) as duration ,COUNT(1) AS output_count
FROM
(
SELECT cdrs.dcustomer AS dcustomer
, (CASE WHEN (cdrs.cnumber like "02%") THEN '02' WHEN (cdrs.cnumber like "05%") THEN '05' END) AS outnumber
, FROM_UNIXTIME(cdrs.start) AS start
, (cdrs.end - cdrs.start) AS duration
, cdrs.talktime AS talktime
FROM cdrs cdrs
INNER JOIN customers c ON c.id = cdrs.dcustomer
WHERE cdrs.start >= #_START and cdrs.start < #_END AND cdrs.dtype = _LATIN1'external'
AND
(c.parent = _ID or cdrs.dcustomer = _ID or c.parent IN (SELECT id FROM customers WHERE parent = _ID))
GROUP BY callid
) cdr
GROUP BY HOUR(start),outnumber
) cdr2
ON cdr2.start = h.idhour
ORDER BY h.idhour
You need a table with all hours, nothing else.
Then use LEFT JOIN with the hours table on the "left" and your current query on the "right":
SELECT b.*
FROM hours h
LEFT JOIN ( ... ) b ON b.hr = h.hr
WHERE h.hr BETWEEN ... AND ...
ORDER BY hr;
Any missing hours will be NULLs in b.*.
I have a strange problem with mysql sum() result.
SELECT `users_limits`.times, SUM( l.times ) AS `result`
FROM `users_limits`
INNER JOIN `users_limits` AS `l`
INNER JOIN `vacation_types` AS `v` ON l.id_vacation_type = v.id_vacation_type
WHERE l.year =2014 AND v.type =0
This query give me result:
times = 10;
result = 30;
But should give me result 10 too, because I have only one record in my db, with these conditions.
you need GROUP BY . try add this
GROUP BY l.times
like that
WHERE l.year =2014 AND v.type =0
GROUP BY l.times
EDIT-:
SELECT `users_limits`.times, SUM( l.times ) AS `result`
FROM `users_limits` l
INNER JOIN `vacation_types` AS `v` ON l.id_vacation_type = v.id_vacation_type
WHERE l.year =2014 AND v.type =0
GROUP BY l.times
