SQl join with count group by - sql-server-2008

I have two tables
one is
Receivesms(Matchdate,Matchtime,Keyword,SmsMessage,Mobileno)
another is
QAoptios(Keyword,Question,Answeroption,Matchdate,Matchtime)
I need to find the count of SmsMessage which have the value same as Answeroption on same Matchdate,Matchtime and same Keyword. and also i need to filter on Receivesms.Matchdate='2012-12-25 00:00:00.000'


SELECT
q.AnswerOption,
COUNT(SmsMessage) TheCount
FROM Receivesms r
INNER JOIN QAoptions q ON r.Matchdate = q.Matchdate
AND r.Matchtime = q.Matchtime
AND r.Keyword = q.keyword
GROUP BY q.AnswerOption;


use can use:
select count(*) from Recievesms r,QAoptios q
where
r.Matchdate = q.Matchdate
and
r.Matchtime = q.Matchtime
and
r. Keyword =q.Keyword
and
r.SmsMessage = q.Answeroption;
or
select count(*) from from Recievesms as r
inner join
QAoptios as q
on
r.SmsMessage = q.Answeroption;


try this one
SELECT count(*) from Receivesms as a inner join QAoptios as b on a.keyword=b.keyword
and a.matchtime=b.matchtime and a.matchdate=b.matchdate and a.value=b.answeroption


SELECT COUNT(R.SmsMessage)
FROM Receivesms R
INNER JOIN QAoptios Q ON
R.Keyword=Q.Keyword AND
R.Matchdate=Q.Matchdate AND
R.Matchtime=Q.Matchtime AND
R.SmsMessage=Q.AnswerOption
Or you can add GROUP BY clause if you want to show AnswerQuestion, like this:
SELECT Q.AnswerOption, COUNT(R.SmsMessage) as TheCount
FROM Receivesms R
INNER JOIN QAoptios Q ON
R.Keyword=Q.Keyword AND
R.Matchdate=Q.Matchdate AND
R.Matchtime=Q.Matchtime AND
R.SmsMessage=Q.AnswerOption
GROUP BY Q.AnswerOption

SQL Query that inner joins on a certain condition

I have this Sql query which I use to create a view. But I need to refactor it, thus it will only perform inner join when SALES.PKY has a duplicate value or is not unique. How can I do it in a single query?
SELECT *
FROM SALES
INNER JOIN MAIN ON
REPLACE(MAIN.KEY,'-','') = SALES.PKY
AND REPLACE (MAIN.B,' ','') = SALES.SK
AND REPLACE (MAIN.P,' ','') = SALES.SP

could you use a with statement to filter like this?
with dups as (
select *
from sales
group by dup_value
having dup_value>1
)
select
dups.*
,main.*
from dups
inner join main
on dups_key=main_key

Here is one method:
SELECT *
FROM SALES INNER JOIN
MAIN
ON REPLACE(MAIN.KEY,'-','') = SALES.PKY AND
REPLACE(MAIN.B,' ','') = SALES.SK AND
REPLACE(MAIN.P,' ','') = SALES.SP JOIN
(SELECT s.PKY
FROM SALES s
GROUP BY s.PKY
HAVING COUNT(*) > 1
) ss
ON ss.PKY = SALES.PKY;

How to convert this to LINQ

I want to convert this query to LINQ.
select sup.firstname, sup.lastname, sup.bankaccountnumber, tbl.total from (select nfcids_id, sum(purchasecost) as total
from tbl_milkpurchases
group by nfcids_id) tbl inner join tbl_nfcids nfc on tbl.nfcids_id = nfc.id inner join tbl_suppliers sup on nfc.suppliers_id = sup.id

Try this query
var obj= from a in Context.tbl_milkpurchases.GroupBy(x=>x.nfcids_id).Select(x=>new{x.nfcids_id,total=Sum(x.purchasecost)})
from b in Context.tbl_nfcids.where(x=>x.id==a.nfcids_id)
from c in Context.tbl_suppliers.where(x=>x.id==b.suppliers_id)
Select new{c.firstname, c.lastname, c.bankaccountnumber, a.total}

Trying to add one last SUM() column to my query in SQL Server 2008

I have the first query which is producing correct results. What I need is I need to add the sum of values as a last column grouped by surveyid. I can't insert Sum(c.value) into the first query because it is an aggregate function. I have the correct query as my second query below. I know there's pivot functionality but not sure if it can be used here. I do realize that there will be repetition but that's okay.
'first query
SELECT
A.PATIENTID, B.STUDENTNUMBER, c.surveyid,
convert(varchar, A.CreatedDate, 107),
C.QuestionID, C.Value, D.Question
FROM
dbo.Survey A, dbo.Patient B, [dbo].[SurveyQuestionAnswer] C, [dbo].[LookupQuestions] D
WHERE
A.PATIENTID = B.ID
and c.SurveyID = A.ID
and c.QuestionID = d.ID
and c.questionid <> 10
ORDER BY
A.PATIENTID
'second query
select
c.surveyid,SUM(c.value) as scores
from
dbo.SurveyQuestionAnswer c
group by
c.SurveyID
order by
SurveyID '---not important

You can use SUM if you add the OVER clause. In this case:
SELECT
A.PATIENTID, B.STUDENTNUMBER, c.surveyid,
convert(varchar, A.CreatedDate, 107),
C.QuestionID, C.Value, D.Question,
SUM(c.Value) OVER(PARTITION BY c.surveyid) scores
FROM
dbo.Survey A
INNER JOIN dbo.Patient B
ON A.PATIENTID = B.ID
INNER JOIN [dbo].[SurveyQuestionAnswer] C
ON c.SurveyID = A.ID
INNER JOIN [dbo].[LookupQuestions] D
ON c.QuestionID = d.ID
WHERE
c.questionid <> 10
ORDER BY
A.PATIENTID

You could use something like this:
SELECT
s.PATIENTID, p.STUDENTNUMBER, sqa.surveyid,
CONVERT(varchar, s.CreatedDate, 107),
sqa.QuestionID, sqa.Value, lq.Question,
Scores = (SELECT SUM(Value) FROM dbo.SurveyQuestionAnswer s2 WHERE s2.SurveyID = s.ID)
FROM
dbo.Survey s
INNER JOIN
dbo.Patient p ON s.PatientID = p.ID
INNER JOIN
[dbo].[SurveyQuestionAnswer] sqa ON sqa.SurveyID = s.ID
INNER JOIN
[dbo].[LookupQuestions] lq ON sqa.QuestionID = lq.ID
WHERE
sqa.questionid <> 10
ORDER BY
s.PATIENTID
By having a subquery with the SUM(...) you should be able to get that sum as a single value and you don't need to use any grouping function

Getting the latest date from a id

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

How to write a select statement inside another select in SQL

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.
