I have a PL/SQL select query like,
select
a.sgm,
b.numbr
from tbl1 a, tbl2 b
where b.itemId = a.itemId
and b.orgId = a.orgId
and a.srvCode = 'F'
and a.nbrCode <> 1
and rownum <= 7
Right now it retrieves like ,
sgm-|-numbr
-----------
abc-|-123
abc-|-678
abc-|-78
abc-|-099
bcd-|-153
bcd-|-123
bcd-|-123
I need to retrieve like ,
sgm-|-numbr
-----------
abc-|-123
bcd-|-153
ie, I need to remove the repeated ones in the first column. ie sgm shouldn't repeat.
Since you are using Oracle, then try this simplified version using a CTE:
WITH CTE as (
SELECT sgm, numbr,
rownum rn
FROM YourTable
)
SELECT CTE.sgm, CTE.numbr
FROM CTE
JOIN (
SELECT sgm, MIN(rownum) minrn
FROM CTE
GROUP BY sgm) t ON CTE.sgm = t.sgm AND CTE.rn = t.minrn
http://sqlfiddle.com/#!4/8d6fb/10
You can replace your query in the CTE above.
Good luck.
SELECT a.sgm, MAX(b.numbr)
FROM tbl1 a INNER JOIN tbl2 b
ON a.itemID = b.itemId
AND a.orgId = b.orgId
WHERE a.srvCode= 'F'
AND a.nbrCode <> 1
AND rownum <= 7
GROUP BY a.sgm
Apply a group function of your choice like MAX() on b.numbr, and apply the grouping on a.sgm, this should do what you need.
Advice : do your joins explicitly, see the difference between your query and mine.
select a.sgm,MAX(b.numbr)
from tbl1 a, tbl2 b
where b.itemId = a.itemId
AND b.orgId= a.orgId
and a.srvCode= 'F'
and a.nbrCode <> 1
and rownum<=7
group by sgm
The value of sgm wont repeat, but maximum value of number will be selected, similarly you can also select the minimum value using the Min function
Use group by function
select
a.sgm,
b.numbr
from tbl1 a, tbl2 b
where b.itemId = a.itemId
and b.orgId = a.orgId
and a.srvCode = 'F'
and a.nbrCode <> 1
and rownum <= 7
group by a.sgm
Select a from tbl a , tbl b WHERE a.userid > b..userid and
a.sgm = b.sgm;

I have the following table:
ID Number Revision
x y 0
x y 1
z w 0
a w 0
a w 1
b m 0
b m 0
I need to return rows that for the same Number thare are more then one ID with the same Revision.Number can be "Null" and I don't need those values.
The output should be:
z w 0
a w 0
I have tried the following query:
SELECT a.id,a.number,a.revision,
FROM table a INNER JOIN
(SELECT id, number, revision FROM table where number > '0'
GROUP BY number HAVING COUNT(*) > 1
) b ON a.revision = b.revision AND a.id != b.id
A little addition- I have rows in my table with the same Number, ID and Revision- I don't need those rows in my query to be displayed!
It is not working! Please help me to figure out how to fix it.
Thanks.
Select t.Id,s.number,t.revision
from (Select number,count(*) 'c'
from table t1
where revision=0
group by number
having count(*) > 1
) s join table t on t.number= s.number
where revision = 0
Another simple approach:
SELECT DISTINCT b.id, b.Number, b.Revision
FROM tbl a
INNER JOIN tbl b
ON a.ID != b.ID AND a.Number = b.Number AND a.Revision = b.Revision;
This is tested in MySql 5, syntax might differ slightly.
You are not that far away with your query:
SELECT a.id,a.number,a.revision
FROM table a
JOIN (
-- multiple id for the same number and revision
SELECT number, revision
FROM table
GROUP BY number, revision
HAVING COUNT(*) > 1
) b
ON a.revision = b.revision
AND a.number = b.number
Untested, but you should get the idea. If your sql-server is a resent version you can solve this with OLAP functions as well.
To filter out rows where the whole row is duplicated we can select only unique rows via group by and having:
SELECT a.id,a.number,a.revision
FROM table a
JOIN (
-- multiple id for the same number and revision
SELECT number, revision
FROM table
GROUP BY number, revision
HAVING COUNT(*) > 1
) b
ON a.revision = b.revision
AND a.number = b.number
GROUP BY a.id,a.number,a.revision
HAVING COUNT(1) = 1
I found a similar problem here: Move duplicated values into unique columns, but I'm not sure that is going to work for me.
The data provided looks like this:
email_address barcode value
1#aol.com 9X3BZBK9CPWVDT16 25
123#verizon.net 9X3L6RD1Y83J8Z6Q 50

456#yahoo.com 9X3BCJ3YXFQ1RFGU 50
456#yahoo.com 9X3L1DVG89CGDBB0 25
But I would like to have it look like this:
EMAIL_ADDRESS BURNED_BARCODE1 value1 BURNED_BARCODE2 value2
1#aol.com 9X3BZBK9CPWVDT16 25
123#verizon.net 9X3L6RD1Y83J8Z6Q 50 9X3PWCQRNX2CNJBC 50

456#yahoo.com 9X3BCJ3YXFQ1RFGU 50 9X3L1DVG89CGDBB0 25
I am trying to consolidate the duplicate coupon codes and values into a BARCODE_2 and value2. I have thought about pivot tables but i cannot seem to get the logic to work.
Any thoughts? Thank you in advance!
You could use the ROW_NUMBER() function for this and a self-join:
;WITH cte AS (SELECT *, ROW_NUMBER()OVER(PARTITION BY email_address ORDER BY barcode) AS RN
FROM Table1)
SELECT a.email_address, a.barcode, a.value, b.barcode AS barcode2, b.value AS value2
FROM cte a
LEFT JOIN cte b
ON a.email_address = b.email_address
AND a.RN = b.RN -1
WHERE a.RN = 1
Demo: SQL Fiddle
Update: You could add a 3rd:
;WITH cte AS (SELECT *, ROW_NUMBER()OVER(PARTITION BY email_address ORDER BY barcode) AS RN
FROM Table1)
SELECT a.email_address, a.barcode, a.value
, b.barcode AS barcode2, b.value AS value2
, c.barcode AS barcode3, c.value AS value3
FROM cte a
LEFT JOIN cte b
ON a.email_address = b.email_address
AND a.RN = b.RN -1
LEFT JOIN cte c
ON a.email_address = c.email_address
AND a.RN = c.RN -2
WHERE a.RN = 1

I have a query like this:
SELECT TV.Descrizione as TipoVers,
sum(ImportoVersamento) as ImpTot,
count(*) as N,
month(DataAllibramento) as Mese
FROM PROC_Versamento V
left outer join dbo.PROC_TipoVersamento TV
on V.IDTipoVersamento = TV.IDTipoVersamento
inner join dbo.PROC_PraticaRiscossione PR
on V.IDPraticaRiscossioneAssociata = PR.IDPratica
inner join dbo.DA_Avviso A
on PR.IDDatiAvviso = A.IDAvviso
where DataAllibramento between '2012-09-08' and '2012-09-17' and A.IDFornitura = 4
group by V.IDTipoVersamento,month(DataAllibramento),TV.Descrizione
order by V.IDTipoVersamento,month(DataAllibramento)
This query must always return something. If no result is produced a
0 0 0 0
row must be returned. How can I do this. Use a isnull for every selected field isn't usefull.
Use a derived table with one row and do a outer apply to your other table / query.
Here is a sample with a table variable #T in place of your real table.
declare #T table
(
ID int,
Grp int
)
select isnull(Q.MaxID, 0) as MaxID,
isnull(Q.C, 0) as C
from (select 1) as T(X)
outer apply (
-- Your query goes here
select max(ID) as MaxID,
count(*) as C
from #T
group by Grp
) as Q
order by Q.C -- order by goes to the outer query
That will make sure you have always at least one row in the output.
Something like this using your query.
select isnull(Q.TipoVers, '0') as TipoVers,
isnull(Q.ImpTot, 0) as ImpTot,
isnull(Q.N, 0) as N,
isnull(Q.Mese, 0) as Mese
from (select 1) as T(X)
outer apply (
SELECT TV.Descrizione as TipoVers,
sum(ImportoVersamento) as ImpTot,
count(*) as N,
month(DataAllibramento) as Mese,
V.IDTipoVersamento
FROM PROC_Versamento V
left outer join dbo.PROC_TipoVersamento TV
on V.IDTipoVersamento = TV.IDTipoVersamento
inner join dbo.PROC_PraticaRiscossione PR
on V.IDPraticaRiscossioneAssociata = PR.IDPratica
inner join dbo.DA_Avviso A
on PR.IDDatiAvviso = A.IDAvviso
where DataAllibramento between '2012-09-08' and '2012-09-17' and A.IDFornitura = 4
group by V.IDTipoVersamento,month(DataAllibramento),TV.Descrizione
) as Q
order by Q.IDTipoVersamento, Q.Mese
Use COALESCE. It returns the first non-null value. E.g.
SELECT COALESCE(TV.Desc, 0)...
Will return 0 if TV.DESC is NULL.
You can try:
with dat as (select TV.[Desc] as TipyDesc, sum(Import) as ToImp, count(*) as N, month(Date) as Mounth
from /*DATA SOURCE HERE*/ as TV
group by [Desc], month(Date))
select [TipyDesc], ToImp, N, Mounth from dat
union all
select '0', 0, 0, 0 where (select count (*) from dat)=0
That should do what you want...
If it's ok to include the "0 0 0 0" row in a result set that has data, you can use a union:
SELECT TV.Desc as TipyDesc,
sum(Import) as TotImp,
count(*) as N,
month(Date) as Mounth
...
UNION
SELECT
0,0,0,0
Depending on the database, you may need a FROM for the second SELECT. In Oracle, this would be "FROM DUAL". For MySQL, no FROM is necessary
I have 2 tables as below-
Table I
ID DATE
1 05/11/12
2 23/11/12
3 29/11/12
4 04/10/12
5 20/11/12
And another table (IH) with the following info-
ID RECNO NOTE
1 1 Open
1 2 Update
1 3 Close
2 1 Open
2 2 Update
2 3 Hold
2 4 Close
3 1 Open
4 1 Open
4 2 Update
5 1 Open
I would like to output a result as shown below, displaying the Note field using the highest value of RecNo for each ID. So using the data above the output should be-
ID DATE NOTE
2 23/11/12 Close
3 29/11/12 Open
The code I have is-
SELECT I.ID, I.DATE, IH.NOTE FROM
I I, IH IH
JOIN (SELECT MAX([RECNO]) [RECNO] FROM
IH
GROUP BY RECNO) IH2 ON IH2.ID = IH.ID AND
IH2.[RECNO] = IH.[RECNO]
JOIN I I2 ON I2.ID = IH.ID WHERE
(I2.DATE>={TS ‘2012-11-22 00:00:002}) GROUP BY I2.ID
However when I execute the code I get-
Invalid Column Name 'RECNO'. Statement(s) could not be prepared.
How about this? Note, haven't tried it, I'm on my Mac at the moment.
SELECT I.ID, I.DATE, IH.NOTE
FROM I I
OUTER APPLY
(SELECT TOP 1 *
FROM IH
WHERE IH.ID = I.ID
ORDER BY RECNO DESC) IH
WHERE I.DATE >= '2012-11-22'
Your SQL is rather, uh, messy.
Assuming you are using SQL Server 2005 or greater, you can use the row_number() function, as follows:
SELECT I.ID, I.DATE, IH.NOTE
FROM I join
(select ih.*, ROW_NUMBER() over (PARTITION by id order by recno desc) as seqnum
from IH
) ih
on IH2.[RECNO] = IH.[RECNO] and seqnum = 1
WHERE I2.DATE>='2012-11-22 00:00:002'
This is assigning a sequence number in the IH table, for each id with the highest record number getting the value "1". The rest is just SQL.
Your original query is simply not correct syntactically, but I think this is what you want based on the description.
and another one
SELECT I.ID, I.DATE
,(Select TOP 1 IH.NOTE FROM IH where IH.ID=i.ID Order by Recno DESC) as Note
from I
WHERE
I.DATE>'20121122'
maybe this will help
SELECT a.ID, a.DATE, b.NOTE FROM a
inner join b on a.ID = b.ID
where b.recno in (select max(bb.recno)
from b as bb where bb.id = b.id)
http://sqlfiddle.com/#!3/fd141/2
If you don't mind the different identifiers, look at this solution:
select t1.MyID, t1.MyDate, y.Note
from t1
join
(
select MyID, max(RecNo) as RecNo
from t2
group by MyID
) x
on t1.MyID = x.MyID
left join
(
select *
from t2
) y
on t1.MyID = y.MyID
and x.RecNo = y.RecNo
where t1.MyDate >= '2012.11.22'
The complete solution is here: http://sqlfiddle.com/#!3/4ca09/3
Update: Oops, forgot to bring in the date in where clause. Updated SQL Fiddle and the query above.
I have query that work for me only when values in the StakeValue don't repeat.
Basically, I need to select maximum values from SI_STAKES table with their relations from two other tables grouped by internal type.
SELECT a.StakeValue, b.[StakeName], c.[ProviderName]
FROM SI_STAKES AS a
INNER JOIN SI_STAKESTYPES AS b ON a.[StakeTypeID] = b.[ID]
INNER JOIN SI_PROVIDERS AS c ON a.[ProviderID] = c.[ID] WHERE a.[EventID]=6
AND a.[StakeGroupTypeID]=1
AND a.StakeValue IN
(SELECT MAX(d.StakeValue) FROM SI_STAKES AS d
WHERE d.[EventID]=a.[EventID] AND d.[StakeGroupTypeID]=a.[StakeGroupTypeID]
GROUP BY d.[StakeTypeID])
ORDER BY b.[StakeName], a.[StakeValue] DESC
Results for example must be:
[ID] [MaxValue] [StakeTypeID] [ProviderName]
1 1,5 6 provider1
2 3,75 7 provider2
3 7,6 8 provider3
Thank you for your help
There are two problems to solve here.
1) Finding the max values per type. This will get the Max value per StakeType and make sure that we do the exercise only for the wanted events and group type.
SELECT StakeGroupTypeID, EventID, StakeTypeID, MAX(StakeValue) AS MaxStakeValue
FROM SI_STAKES
WHERE Stake.[EventID]=6
AND Stake.[StakeGroupTypeID]=1
GROUP BY StakeGroupTypeID, EventID, StakeTypeID
2) Then we need to get only one return back for that value since it may be present more then once.
Using the Max Value, we must find a unique row for each I usually do this by getting the Max ID is has the added advantage of getting me the most recent entry.
SELECT MAX(SMaxID.ID) AS ID
FROM SI_STAKES AS SMaxID
INNER JOIN (
SELECT StakeGroupTypeID, EventID, StakeTypeID, MAX(StakeValue) AS MaxStakeValue
FROM SI_STAKES
WHERE Stake.[EventID]=6
AND Stake.[StakeGroupTypeID]=1
GROUP BY StakeGroupTypeID, EventID, StakeTypeID
) AS SMaxVal ON SMaxID.StakeTypeID = SMaxVal.StakeTypeID
AND SMaxID.StakeValue = SMaxVal.MaxStakeValue
AND SMaxID.EventID = SMaxVal.EventID
AND SMaxID.StakeGroupTypeID = SMaxVal.StakeGroupTypeID
3) Now that we have the ID's of the rows that we want, we can just get that information.
SELECT Stakes.ID, Stakes.StakeValue, SType.StakeName, SProv.ProviderName
FROM SI_STAKES AS Stakes
INNER JOIN SI_STAKESTYPES AS SType ON Stake.[StakeTypeID] = SType.[ID]
INNER JOIN SI_PROVIDERS AS SProv ON Stake.[ProviderID] = SProv.[ID]
WHERE Stake.ID IN (
SELECT MAX(SMaxID.ID) AS ID
FROM SI_STAKES AS SMaxID
INNER JOIN (
SELECT StakeGroupTypeID, EventID, StakeTypeID, MAX(StakeValue) AS MaxStakeValue
FROM SI_STAKES
WHERE Stake.[EventID]=6
AND Stake.[StakeGroupTypeID]=1
GROUP BY StakeGroupTypeID, EventID, StakeTypeID
) AS SMaxVal ON SMaxID.StakeTypeID = SMaxVal.StakeTypeID
AND SMaxID.StakeValue = SMaxVal.MaxStakeValue
AND SMaxID.EventID = SMaxVal.EventID
AND SMaxID.StakeGroupTypeID = SMaxVal.StakeGroupTypeID
)
You can use the over clause since you're using T-SQL (hopefully 2005+):
select distinct
a.stakevalue,
max(a.stakevalue) over (partition by a.staketypeid) as maxvalue,
b.staketypeid,
c.providername
from
si_stakes a
inner join si_stakestypes b on
a.staketypeid = b.id
inner join si_providers c on
a.providerid = c.id
where
a.eventid = 6
and a.stakegrouptypeid = 1
Essentially, this will find the max a.stakevalue for each a.staketypeid. Using a distinct will return one and only one row. Now, if you wanted to include the min a.id along with it, you could use row_number to accomplish this:
select
s.id,
s.maxvalue,
s.staketypeid,
s.providername
from (
select
row_number() over (order by a.stakevalue desc
partition by a.staketypeid) as rownum,
a.id,
a.stakevalue as maxvalue,
b.staketypeid,
c.providername
from
si_stakes a
inner join si_stakestypes b on
a.staketypeid = b.id
inner join si_providers c on
a.providerid = c.id
where
a.eventid = 6
and a.stakegrouptypeid = 1
) s
where
s.rownum = 1
