I am trying to make a query using a condition based in the amont of rows obtained in another query. But I cannot get the correct way. Does any body can help me ? What I am trying to do is :
SELECT ChildDummyTable.Id ChildDummyTableId,
ParentDummyTable.Id ParentDummyTableId
FROM [DummyTable] ChildDummyTable
INNER JOIN [DummyTable] ParentDummyTable
ON ParentDummyTable.Id = ChildDummyTable.ParentDummyRowId
where (SELECT DummyRow2 FROM DummyTable2 WHERE DummyTableId=ChildDummyTable.Id
except SELECT DummyRow2 FROM DummyTable2 ParentDummyTable2
WHERE ParentDummyTable2.DummyTableId=DummyTable.Id).COUNT(DummyRow2)>0
You can use EXISTS:
SELECT ChildDummyTable.Id ChildDummyTableId,
ParentDummyTable.Id ParentDummyTableId
FROM [DummyTable] ChildDummyTable
INNER JOIN [DummyTable] ParentDummyTable
ON ParentDummyTable.Id = ChildDummyTable.ParentDummyRowId
WHERE EXISTS(SELECT DummyRow2 FROM DummyTable2
WHERE DummyTableId=ChildDummyTable.Id
EXCEPT
SELECT DummyRow2 FROM DummyTable2 ParentDummyTable2
WHERE ParentDummyTable2.DummyTableId=DummyTable.Id)
with a as
(SELECT ChildDummyTable.Id ChildDummyTableId
,ParentDummyTable.Id ParentDummyTableId
,ROW_NUMBER() OVER(PARTITION by
ChildDummyTable.Id ChildDummyTableId
,ParentDummyTable.Id ParentDummyTableId
)
aS duplicateRecCount
FROM [DummyTable] ChildDummyTable
INNER JOIN [DummyTable] ParentDummyTable
ON ParentDummyTable.Id = ChildDummyTable.ParentDummyRowId
)
Select * from a
where duplicateRecCount > 1

In one of my SQL views I am using an inline select statement with a where clause.
The outline of my view is like
ALTER VIEW [dbo].[vw_autumn]
AS
SELECT
BookNumber, Title, shopNo
FROM
(SELECT
BookNumber, Title, shopNO
FROM
(SELECT DISTINCT
(sum_vnr) AS BookNumber,
navn1 AS Title,
tik AS ShopNO,
ROW_NUMBER() OVER (PARTITION BY sum_vnr, tik ORDER BY sum_vnr DESC) AS rownumber
FROM
sum s
INNER JOIN
hod h ON s.tik = h.tik
WHERE
s.aar = (SELECT currentyear
FROM SemesterInfo
WHERE SemName = 'Autumn')
AND CAST(s.sum_vnr AS BIGINT) > 10000
AND (s.id LIKE 'h%' OR s.id LIKE 'H%' OR s.id LIKE 'j%'
OR s.id LIKE 'J%')) a
WHERE rownumber = 1
) b
LEFT JOIN (
------
) p ON b.ShopNO = p.tikk
AND b.ISBN = p.vnr
LEFT JOIN table_k k ON p.aar = k.aar
GO
And if I remove the WHERE clause of
WHERE
s.aar = (SELECT currentyear
FROM SemesterInfo
WHERE SemName = 'Autumn')
and shorten it to
WHERE s.aar =19
I am getting the result of view very quickly. But I am trying to add some dynamic nature to this query and selecting this constant from a settings table
Any thoughts on this? Why is the query taking an indefinite time to load with an inline Where clause?
:try with IN insted of =
WHERE
s.aar in (SELECT currentyear
FROM SemesterInfo
WHERE SemName = 'Autumn')
Rewrite the subquery as a join.
INNER JOIN SemesterInfo si
ON s.aer = si.currentYear
WHERE si.SemName = 'Autumn'
If that doesn't do it, consider keeping this syntax and creating an index on SemName
SELECT pp.pat_key, MAX(pp.PROV_NPI) [Provider_ID], CONCAT(pp.LAST_NM,' ',pp.FIRST_NM) [Provider_Name]
INTO pat_primary_provider
FROM TRDW.dbo.PATIENT_PROVIDER pp
WHERE IS_PCP=1
AND pat_key IN (SELECT Consumer_ID FROM CareWire0521)
GROUP BY pp.PAT_KEY, pp.last_nm, pp.FIRST_NM;
SELECT ppp.*
INTO ppp1
FROM (SELECT PAT_KEY, MAX(provider_ID) AS maxprov FROM pat_primary_provider GROUP BY PAT_KEY) AS x
INNER JOIN pat_primary_provider AS ppp ON ppp.PAT_KEY = x.PAT_KEY AND ppp.Provider_ID = x.maxprov;
I need to get the results of ppp1 only using one query (no INTO statements) in SQL Server. Please help.
Simply put the first query into a CTE (without the INTO clause). Then select from that.
;WITH pat_primary_provider AS
(
-- The first query goes here
)
-- The second query goes here
But something like below might also return the PAT_KEY's with the maximum PROV_NPI:
SELECT TOP 1 WITH TIES
PAT_KEY,
MAX(PROV_NPI) AS [Max_Provider_ID],
CONCAT(LAST_NM,' ',FIRST_NM) AS [Patient_Provider_Full_Name]
FROM TRDW.dbo.PATIENT_PROVIDER pp
WHERE IS_PCP = 1
AND PAT_KEY IN (SELECT Consumer_ID FROM CareWire0521)
GROUP BY PAT_KEY, LAST_NM, FIRST_NM
ORDER BY row_number() over (order by MAX(PROV_NPI) desc);
Whats wrong with just inserting the first query as subqueries into the second?
SELECT ppp.*
FROM (SELECT PAT_KEY, MAX(provider_ID) AS maxprov FROM (SELECT pp.pat_key, MAX(pp.PROV_NPI) [Provider_ID], CONCAT(pp.LAST_NM,' ',pp.FIRST_NM) [Provider_Name]
FROM TRDW.dbo.PATIENT_PROVIDER pp
WHERE IS_PCP=1
AND pat_key IN (SELECT Consumer_ID FROM CareWire0521)
GROUP BY pp.PAT_KEY, pp.last_nm, pp.FIRST_NM) GROUP BY PAT_KEY) AS x
INNER JOIN (SELECT pp.pat_key, MAX(pp.PROV_NPI) [Provider_ID], CONCAT(pp.LAST_NM,' ',pp.FIRST_NM) [Provider_Name]
FROM TRDW.dbo.PATIENT_PROVIDER pp
WHERE IS_PCP=1
AND pat_key IN (SELECT Consumer_ID FROM CareWire0521)
GROUP BY pp.PAT_KEY, pp.last_nm, pp.FIRST_NM) AS ppp ON ppp.PAT_KEY = x.PAT_KEY AND ppp.Provider_ID = x.maxprov;
Trying to use Distinct in select statement but not getting the desired result. I want CaseID to be returned for the last updated comment only. Below is the query that I am trying to use.
Select Distinct av.CaseID,fr.Rule_Description, av.Date, av.Status, fr.RULE_PRIORITY, ac.User_comments, max(ac.Comment_PostDate),ac.UserID
From tblAlertView av
Join tblAlertComment ac
on av.CaseID = ac.CaseID
Join tblFBLRule fr
on av.RuleID = fr.Rule_ID
Join TBLUSER usr
on ac.UserID = usr.USERID
group by av.CaseID, fr.Rule_Description, av.Date, av.Status, fr.RULE_PRIORITY, ac.User_comments, ac.Comment_PostDate,ac.UserID
Query Result
Remove
ac.Comment_PostDate
from group by clause
Rather than using JOIN to get to tblAlertComment, if you use CROSS APPLY you can specify to just return the top 1 comment per case:
SELECT av.CaseID,
fr.Rule_Description,
av.Date,
av.Status,
fr.RULE_PRIORITY,
ac.User_comments,
ac.Comment_PostDate,
ac.UserID
FROM tblAlertView AS av
INNER JOIN tblFBLRule AS fr
ON av.RuleID = fr.Rule_ID
CROSS APPLY
( SELECT TOP 1 ac.User_comments, ac.Comment_PostDate, ac.UserID
FROM tblAlertComment AS ac
INNER JOIN tblUser AS usr
ON usr.UserID = ac.UserID
WHERE ac.CaseID = av.CaseID
ORDER BY ac.Comment_PostDate DESC
) AS ac;
How to use this below query as join instead of subquery. It's resulting poor performance
SELECT EBIJ.* FROM BUDLINEITEMS EBIJ

WHERE E.ImportKeyId IS NULL
OR

WHERE NOT EXISTS (SELECT 1
FROM External_Blk_Itm_JounalEntries E
WHERE EBIJ.ReferenceId = E.ImportKeyId )
I am currently having trouble with my query after joining two tables I am getting duplicated records. What i want to do is get the details from table 1 and the payment record from table 2 with same date.. here is my query.
SELECT dbo.tblautoipekonek.ipno,
dbo.tblautoipekonek.awbno,
dbo.tblautoipekonek.ipamount,
dbo.tblautoipekonek.orno,
dbo.tbladdfunds.username,
dbo.tbladdfunds.newctfbal,
dbo.tbladdfunds.addedctfamt,
dbo.tbladdfunds.oldctfbal,
dbo.tbladdfunds.newipbal,
dbo.tbladdfunds.addedipamt,
dbo.tbladdfunds.oldipbal,
dbo.tbladdfunds.date,
dbo.tblautoipekonek.date AS Expr1
FROM dbo.tblautoipekonek
LEFT OUTER JOIN dbo.tbladdfunds
ON dbo.tblautoipekonek.date = dbo.tbladdfunds.date
WHERE
( dbo.tblautoipekonek.date = '06/06/2014' )
Hi you can use "Distinct" keyword at after "select" keyword. it will get the single record.
Good to replace dbo.tablename with alias name give to tablename as
select
distinct
auto.IPNo, ... ---here you can add other column of this table.
fund.AddedCTFAmt --same thing done here.
FROM tblAutoIPEkonek auto
LEFT OUTER JOIN dbo.tblAddfunds fund
ON auto.Date = fund.Date --try to add more join condition so filteration done here of data which is fastest/
WHERE (auto.Date = '06/06/2014')
SELECT DISTINCT dbo.tblautoipekonek.ipno,
dbo.tblautoipekonek.awbno,
dbo.tblautoipekonek.ipamount,
dbo.tblautoipekonek.orno,
dbo.tbladdfunds.username,
dbo.tbladdfunds.newctfbal,
dbo.tbladdfunds.addedctfamt,
dbo.tbladdfunds.oldctfbal,
dbo.tbladdfunds.newipbal,
dbo.tbladdfunds.addedipamt,
dbo.tbladdfunds.oldipbal,
dbo.tbladdfunds.date,
dbo.tblautoipekonek.date AS Expr1
FROM dbo.tblautoipekonek
LEFT OUTER JOIN dbo.tbladdfunds
ON dbo.tblautoipekonek.date = dbo.tbladdfunds.date
WHERE
( dbo.tblautoipekonek.date = '06/06/2014' )
GROUP BY dbo.tblautoipekonek.ipno,
dbo.tblautoipekonek.awbno,
dbo.tblautoipekonek.ipamount,
dbo.tblautoipekonek.orno,
dbo.tbladdfunds.username,
dbo.tbladdfunds.newctfbal,
dbo.tbladdfunds.addedctfamt,
dbo.tbladdfunds.oldctfbal,
dbo.tbladdfunds.newipbal,
dbo.tbladdfunds.addedipamt,
dbo.tbladdfunds.oldipbal,
dbo.tbladdfunds.date,
dbo.tblautoipekonek.date AS Expr1
Not sure if this will work for you but this is what I would use:
SELECT
p.ipno,
p.awbno,
p.ipamount,
p.orno,
f.username,
f.newctfbal,
f.addedctfamt,
f.oldctfbal,
f.newipbal,
f.addedipamt,
f.oldipbal,
f.date,
p.date Expr1
FROM
dbo.tblautoipekonek p
CROSS APPLY
(
SELECT TOP 1
*
FROM
dbo.tbladdfunds f
WHERE
p.date = f.date
ORDER BY
f.newipbal DESC
) f
This will get you one line from each entry in dbo.tblautoipekonek joined with the matching date entry from dbo.tbladdfunds which has the highest value in newipbal
