I am trying to run this query with using subquery but not able to fetch my result .is any one here to help me in geting it correct.
SELECT u.uv_id ID
, d.sd_code Code
, u.uv_name Title
, u.uv_nirf Nirf
, (SELECT sd_code
FROM vm_university_type t
JOIN vm_seo_detail d
ON t.ut_id = d.sd_ty_id
AND d.sd_ty = 'vm_university_type') AS 'University Type'
, a.ab_name 'Approved By'
, u.uv_seats Seats
, g.ug_name 'University Group'
FROM vm_universities u
JOIN vm_seo_detail d
ON u.uv_id = d.sd_ty_id
AND d.sd_ty = 'vm_universities'
JOIN vm_university_type t
ON u.uv_ut_id = t.ut_id
JOIN vm_approved_by a
ON u.uv_ab_id = a.ab_id
JOIN vm_caste c
ON u.uv_c_id = c.caste_id
JOIN vm_university_groups g
ON u.uv_ug_ids = g.ug_id;
i got this error Subquery returns more than 1 row
(SELECT `sd_code` FROM vm_university_type INNER JOIN vm_seo_detail ON (vm_university_type.ut_id = vm_seo_detail.sd_ty_id AND vm_seo_detail.sd_ty = 'vm_university_type') WHERE vm_university_type.ut_id=vm_universities.uv_ut_id ) AS 'University Type' ,
You do not need subquery at all. The column Code in SELECT statement contains University Type
Try below query.
SELECT vm_universities.uv_id AS 'ID' , vm_seo_detail.sd_code AS 'Code',
vm_universities.uv_name AS 'Title' , vm_universities.uv_nirf AS 'Nirf',
vm_approved_by.ab_name AS 'Approved By' , vm_universities.uv_seats as 'Seats',
vm_university_groups.ug_name AS 'University Group'
FROM vm_universities INNER JOIN vm_seo_detail
ON (vm_universities.uv_id = vm_seo_detail.sd_ty_id
AND vm_seo_detail.sd_ty = 'vm_universities')
INNER JOIN vm_university_type
ON (vm_universities.uv_ut_id = vm_university_type.ut_id)
INNER JOIN vm_approved_by
ON (vm_universities.uv_ab_id = vm_approved_by.ab_id)
INNER JOIN vm_caste
ON (vm_universities.uv_c_id = vm_caste.caste_id)
INNER JOIN vm_university_groups
ON (vm_universities.uv_ug_ids = vm_university_groups.ug_id);
SELECT `sd_code` FROM vm_university_type INNER JOIN vm_seo_detail ON (vm_university_type.ut_id = vm_seo_detail.sd_ty_id AND vm_seo_detail.sd_ty = 'vm_university_type')
looks like you forgot WHERE section in subquery, that will bind it to main query. something like
WHERE vm_university_type.ut_id=vm_universities.uv_ut_id
ps. and why you need this subquery at all, if you already join with vm_university_type in main query?

Please check the below code.
SELECT
`order`.idorder
, order_status_code.idorder_status_code
, order_status_code.order_status_code
, user.iduser
, `order`.required_delivery_date
, `order`.cancel
, `order`.date_created
, `order`.last_updated
, COUNT(order_item.idorder_item)
from
`order`
INNER JOIN order_status_code
ON `order`.idorder_status_code = order_status_code.idorder_status_code
INNER JOIN user
ON `order`.iduser = user.iduser
INNER JOIN order_item
ON order_item.idorder = `order`.`idorder`
WHERE
`order`.iduser = 1
In here, I want the COUNT(order_item.idorder_item) to return the number of items under the idorder. In other words, if I run that SQL Part along, that would be like below
SELECT
COUNT(`idorder_item`)
from
order_item
where
idorder = 1
How can I get this done in my main query?
SELECT `order`.idorder,
order_status_code.idorder_status_code,
order_status_code.order_status_code,
user.iduser,
`order`.required_delivery_date,
`order`.cancel,
`order`.date_created,
`order`.last_updated,
COUNT(order_item.idorder_item),
(SELECT COUNT(`idorder_item`)
from order_item
where idorder=1) as count_idorder_item
from `order`
INNER JOIN order_status_code ON `order`.idorder_status_code = order_status_code.idorder_status_code
INNER JOIN user ON `order`.iduser = user.iduser
INNER JOIN order_item ON order_item.idorder = `order`.`idorder`
WHERE `order`.iduser= 1
I have this query which i believe can be optimized:
SELECT floors.id, floors.floor FROM floors
WHERE floors.societies_id = 1
AND floors.status = 'Y'
AND floors.id NOT IN (
SELECT DISTINCT(floors.id) FROM floors
INNER JOIN societies ON societies.id = floors.societies_id
INNER JOIN resident_floors ON resident_floors.floors_id = floors.id
WHERE societies.id = 1
AND floors.status = 'Y'
)
Is this query fine to use or there it can be improved..?
It looks like you want to get all floors that aren't present in resident_floors. For this we can left join RF in and ask for only rows where the join failed resulting in a null in RF:
SELECT floors.* FROM floors
INNER JOIN societies ON societies.id = floors.societies_id
LEFT JOIN resident_floors ON resident_floors.floors_id = floors.id
WHERE societies.id = 1
AND floors.status = 'Y'
AND resident_floors.floors_id IS NULL
Got 2 tables as shown above. I want to update 'leaverecord.Consumed' from 'approved.Consumed' WHERE the leaverecord.name = approved.name and leaverecord.leavetype = approved.leavetype. Tried below query by getting error of 'Invalid use of group function
UPDATE leaverecord r INNER JOIN approved a
ON r.name = a.name
SET r.Consumed = SUM(DATEDIFF(a.todate,a.fromdate))
WHERE r.leavetype = a.leavetype AND
r.name = a.name
Calculate the consumed in a subquery and INNER JOIN it with leaverecord and then do the UPDATE like below. No WHERE clause needed.
Try this:
update leaverecord r
inner join (
select name, leavetype, sum(datediff(todate,fromdate)) consumed
from approved
group by name, leavetype
) a on r.name = a.name
and r.leavetype = a.leavetype
set r.consumed = a.consumed;
I run the above sql statement and i got this.[IMG]http://i1093.photobucket.com/albums/i422/walkgirl_1993/asd-1_zps5506632e.jpg[/IMG] i'm trying display the latest date which you can see the 3 and 4. For caseid 3, it should display the latest row which is the 2012-12-20 16:12:36.000. I tried using group by, order by. Google some website said to use rank but i'm not sure about the rank as i dont really get rank. Some suggestions?
select [Case].CaseID, Agent.AgentName, Assignment.Description, A.AgentName as EditedBy, A.DateEdited from Agent inner join [Case-Agent] on [Case-Agent].AgentID = Agent.AgentID inner join [Assignment] on Assignment.AssignmentID = [Case-Agent].AssignmentID inner join [Case] on [Case].CaseID = [Case-Agent].CaseID inner join (select EditedCase.CaseID, [EditedCase].DateEdited, [Agent].AgentName from EditedCase inner join [Agent] on [Agent].AgentID = [EditedCase].AgentID) A on A.CaseID = [Case].CaseID where [Assignment].AssignmentID = 0
To do it using RANK you just need to add the RANK to the subquery and get to rank the DateEdited for each CaseID and Agent and then in the main query put a WHERE clause to only select rows where the rank is 1. I think I have got the partition clause right - its a bit hard without seeing your data.
Like this:
SELECT
[Case].CaseID
,Agent.AgentName
,Assignment.Description
,A.AgentName AS EditedBy
,A.DateEdited
FROM Agent
INNER JOIN [Case-Agent] ON [Case-Agent].AgentID = Agent.AgentID
INNER JOIN [Assignment] ON Assignment.AssignmentID = [Case-Agent].AssignmentID
INNER JOIN [Case] ON [Case].CaseID = [Case-Agent].CaseID
INNER JOIN (SELECT
EditedCase.CaseID
,[EditedCase].DateEdited
,[Agent].AgentName
,RANK ( ) OVER (PARTITION BY EditedCase.CaseID, [Agent].AgentName
ORDER BY [EditedCase].DateEdited DESC ) AS pos
FROM EditedCase
INNER JOIN [Agent] on [Agent].AgentID = [EditedCase].AgentID) A on A.CaseID = [Case].CaseID
WHERE [Assignment].AssignmentID = 0
AND pos = 1
You could also change the sub query into an aggregate query that brings back the MAX date like this:
SELECT
[Case].CaseID
,Agent.AgentName
,Assignment.Description
,A.AgentName AS EditedBy
,A.DateEdited
FROM Agent
INNER JOIN [Case-Agent] ON [Case-Agent].AgentID = Agent.AgentID
INNER JOIN [Assignment] ON Assignment.AssignmentID = [Case-Agent].AssignmentID
INNER JOIN [Case] ON [Case].CaseID = [Case-Agent].CaseID
INNER JOIN (SELECT
EditedCase.CaseID
,MAX([EditedCase].DateEdited) AS DateEdited
,[Agent].AgentName
FROM EditedCase
INNER JOIN [Agent] on [Agent].AgentID = [EditedCase].AgentID
GROUP BY
EditedCase.CaseID
,[Agent].AgentName) A on A.CaseID = [Case].CaseID
WHERE [Assignment].AssignmentID = 0
AND pos = 1
You were on the right track; you need to use a ranking function here, for example row_number():
with LatestCase as
(
select [Case].CaseID
, Agent.AgentName
, Assignment.Description
, A.AgentName as EditedBy
, A.DateEdited
, caseRank = row_number() over (partition by [Case].CaseID order by A.DateEdited desc)
from Agent
inner join [Case-Agent] on [Case-Agent].AgentID = Agent.AgentID
inner join [Assignment] on Assignment.AssignmentID = [Case-Agent].AssignmentID
inner join [Case] on [Case].CaseID = [Case-Agent].CaseID
inner join
(
select EditedCase.CaseID
, [EditedCase].DateEdited
, [Agent].AgentName
from EditedCase
inner join [Agent] on [Agent].AgentID = [EditedCase].AgentID
) A on A.CaseID = [Case].CaseID where [Assignment].AssignmentID = 0
)
select *
from LatestCase
where caseRank = 1
Can anyone tell me what is wrong with this query?
it gives a syntax error near the 2nd select
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition)
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
looks like you are missing a comma after MAX(h.edition)
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition),
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
besides the comma, you are selecting two fields in your subquery
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition),
(SELECT preview FROM title_history WHERE idtitle_history = MAX(h.idtitle_history)),
(SELECT [file] FROM title_history WHERE idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
Adding to bluefeet's answer, you may want to check for reserved words. "File" for example is a reserved word in sql server.
Alias it as a virtual table. Change something like
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition)
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder) as virtual_column_alias;
Check this out. Hope this will work.
