Query to find the latest two transactions for each Group

Hi All,
Consider the following sets of records in a table test.
Group---Tran_Dt---SlNo
c1 10/10/2003 1
c1 10/10/2003 2
c1 10/10/2003 3
c1 11/10/2003 1
c2 10/10/2003 1
c2 10/10/2003 2
c2 11/10/2003 1
c2 11/10/2003 2
c2 11/10/2003 3
c3 10/10/2003 1
c3 10/10/2003 2
c3 10/10/2003 3
I want to list out the latest two transactions for each group irrespective of the slno and trans_dt as below:
group tran_dt SlNo
c1 11/10/2003 1
c1 10/10/2003 3
c2 11/10/2003 3
c2 11/10/2003 2
c3 10/10/2003 3
c3 10/10/2003 2
Any help on this would be appreciated.
Thanks
Walter Nicholas T

Hi Walter,
Please try following query.
select Group,tran_dt,sino from
select Group,tran_dt,sino,(DENSE_RANK()OVER (PARTITION BY Group ORDER BY tran_dt desc,sino desc)) rank from test
) where rank between 1 and 2
Thanks,
Samir

Need to find the latest security update for firefox browser

Due to PCI SOX compliance i need Firefox should be updated with latest security updates.
Please let me know the way from where i can get the latest security update for different version of Firefox.

Hello,
If you update Firefox and its plugins to the last versions you will have the last security updates:
*[http://www.mozilla.org/en-US/firefox/new/ Firefox]
*[http://www.mozilla.org/en-US/plugincheck/ Check Plugins]

Where can I find the latest security hotfix for CF 9.0.2?

ZDNet announces there is a security hotfix for ColdFusion but provides no link to where I can read about it or download it. I go to the Adobe site and look for it by browsing and searching and can't find it. It's been hidden well.
Maybe the ZDNet announcement was made prior to Adobe updating their website? Or maybe I just can't find what is obvious for others.

Adobe published it yesterday, you just have to know where to look: http://helpx.adobe.com/security.html is always updated with the latest from the Adobe Security team. More specifically you are looking for this: http://helpx.adobe.com/security/products/coldfusion/apsb14-23.html

Query to find the latest record with respect to the current status

Dear gurus
I have the following data in a table
Customernum
bkcode
reqtdate
Prevstat
currstat
The data will be like this
CustomerNum bkcode reqdate prevstat currstat
5900 1 03-Aug-12 0 1
5900 1 06-Aug-12 1 0
5900 5 22-Jun-12 0 1
If a customer has an issue to solved, a record is added with bkcode , register date and currstat will be 1
If the issue is resolved for the bookingcode,a new record is added, the currentstatus will become 0. and prev stat will show 1. Row no 1 and 2 reflects this case
If this table is queried for finding the unresolved issues. the output should be only the Last row of the above example. since issue with bookingcode 1 has been resolved
I have trying hard to get this thing confused what to use Lead or Max
Kindly guide me

Hi,
one way here:
WITH mytable(CustomerNum, bkcode, reqdate, prevstat, currstat)
AS
   SELECT 5900, 1, TO_DATE('03-Aug-12', 'DD-Mon-YY'), 0, 1 FROM DUAL UNION ALL
   SELECT 5900, 1, TO_DATE('06-Aug-12', 'DD-Mon-YY'), 1, 0 FROM DUAL UNION ALL
   SELECT 5900, 5, TO_DATE('22-Jun-12', 'DD-Mon-YY'), 0, 1 FROM DUAL
SELECT CustomerNum, bkcode, reqdate, prevstat, currstat
FROM (SELECT a.*
             , ROW_NUMBER() OVER (PARTITION BY CustomerNum, bkcode
                                       ORDER BY reqdate DESC) AS rn
          FROM mytable a
WHERE rn=1
   AND currstat=1;
CUSTOMERNUM     BKCODE REQDATE     PREVSTAT   CURRSTAT
       5900          5 22-JUN-12          0          1Regards.

Need to find the dependent object details for an object.

Hi,
Is there any query to find the dependent object details for any object. Like if mview is built on a table, then i should be able to find the table name with out checking code of the mview. Thanks in-advance for your support. similar way for view and functions or procedures etc...
Regards
DBA.

Hi all,
Thanks a lot for your inputs. seems i have not given full details in my post. I need to have a SQL Query to find the dependent object details not DDL.
if i give a metriealized view name, i should get the base table names directly not DDLs...
if i give index name i should get its corresponding table name(off course i got this already)...
if i give a function name, i should get all the tables which are being in the function...etc...
i am looking for a script which will cover all the aspects.....i hope i have given now enough information for this....

How to handle goup sub total for each group in oracle query ?

hi,
i want to handle one complex thing in oracle query.
i have a grouping in my oracle query.
i want to do sub total for each group in query and after that i want to subtract one group sub total from previous group subtotal ?
so how can i handle this in oracle query ?
any help is greatly appreciated.
thanks.

Hello
Interesting requirement.
I wonder why are you not using these calculation during the display time. If it is acceptable then you can try using the custom formula with the running total combination in crystral report to achieve to get the required results.

Please reply

To get the first two rows from each group, you could do this:
Use the ROW_NUMBER() analytic function (see http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions137.htm#i86310)
Now, your question isn't clear what you mean by "last" two rows. Last in what order? Whatever it is, you can use the ORDER BY part of the ROW_NUMBER() function to specify the ordering, and reverse it using DESC - for example:
select acn, adate, cost, appl from (
 select acn, adate, cost, appl,
 row_number() over (partition by acn order by adate desc) as rn
 from acntab
where rn <= 2
order by acn, rnHTH

Last() not returning correct value within for-each-group

I've found inconsistent results between JDeveloper and SOA Suite using the xslt 2.0 for-each-group construct.
<xsl:for-each-group select="Po/PoLine" group-by="itemId">
<xsl:if test="position()=1">
<GroupCount>
<xsl:value-of select="last()"/>
</GroupCount>
</xsl:if>
</xsl:for-each-group>
What I expect is the function last() to give me the number of groups which is the unique number of itemIds.
In JDeveloper 10.1.3.4, testing this construct gives me what I expect.
At run-time (deployed to 10.1.3.3 SOA Suite), the value returned is the total number of records, not the number of groups.
For example, given the following XML
<Po>
<PoLine>
<itemId>001</itemId>
<description>Hammer</description>
<quantity>10</quantity>
</PoLine>
<PoLine>
<itemId>001</itemId>
<description>Hammer</description>
<quantity>10</quantity>
</PoLine>
<PoLine>
<itemId>002</itemId>
<description>Nail</description>
<quantity>10</quantity>
</PoLine>
</Po>
Grouping by itemId, last() should return 2 as there are two groups (001 and 002). JDeveloper does this.
When deployed to SOA Suite, last() returns 3.
Any ideas?

Hi,
if JDeveloper is doing the right thing then this issue should be reported to the SOA Suite forum or BPEL BPEL , what do you think ?

Top N for each grouping?

Is there a way to show in OBIEE the Top N results for each group?
I want to show the top 10 amounts for each region in my table. If using a Top N filter, it returns the Top N overall results. I tried creating a pivot table and using 'Region' as the section separator, but got the same results. It's only returning 10 amounts total, and I want to see 10 amounts for each region.
Kevin

Yep,
Use the by statement:
TOPN("F1 Revenue"."1-01 Revenue (Sum All)", 10 by "D2 Market"."M01 Market")
