VINCENNES     VINCENNES SUB     12/29/2009 16:23In the above set of records i want to show only the latest record based on the time stamp, so i used the following calculation:LAST_VALUE(Os Activity.Rec Timestamp) OVER(PARTITION BY Os Activity.Sub District )
But for some reason its giving me the following set:

How to find out the latest Record in per_all_people_f and per_all_assignme

Hi ,
How to find out the latest Record in per_all_people_f and per_all_assignments_f
Requirement : Need to find out the latest record in per_all_people_f and per_all_assignments_f to update the attribute column with pre defined value . Its not possible to track only with person_id / assignment_id and effective end date
SELECT pp_id
FROM (SELECT app.person_id pp_id,
asf.*
FROM apps.per_all_people_f app,
apps.per_all_assignments_f asf
WHERE --app.person_id=123568 and
asf.person_id = app.person_id AND
app.effective_end_date = to_date('31-dec-4712') AND
asf.effective_end_date = to_date('31-dec-4712')
GROUP BY app.person_id)
HAVING COUNT(pp_id) > 1
GROUP BY pp_id
This query also returns more than 1 value for person_id .
It would be great if you put comment on this .. Thanks in advance ,
Arya

Latest record to get from MSEG Table

Hi frnds,
I am getting multiple records against material no. i want single record and latest one.
SELECT DISTINCT MBLNR MATNR LIFNR
        FROM MSEG
        INTO TABLE IT_MSEG
        WHERE MATNR IN S_MATNR
        ORDER BY MATNR MBLNR DESCENDING.
S_MATNR = multiple matnr
eg: matnr   mblnr lifnr
      test     1        abc
      test     2        abc
      test2   4        xyz
      test3   3        abc
      test3   5        vvvv
I want in my ITAB.
eg: matnr   mblnr lifnr
      test     1        abc
      test2   4        xyz
      test3   5        vvvv
Here I am sorting with mblnr to pick latest record.
How i will get.

Hi,
    just do one thing if after sorting you are getting first record of latest record in each material then use
delete adjacent duplicates from itab comparing matnr.

Display latest Record First

Hi,
Could someone tell me where in forms builder you can configure the form so the latest record is displayed first in the application.
As an example i query someones name in the application and i'd like to view the latest record saved to that person (there is a join between people and my new table). At the moment my custom form returns the first record entered against them.
Thanks
Steve

You will have to identify this record in some way, e.g. by an increasing primary key number, or a date_created column. Then you have to order by this column in descending order in your form.

Can any one tell me how to select latest record

Hi,
Can any one tell me how to select latest record. Below is the requirement
select * from a where a_Date=v_date.
out of thousand records with matched condition i need to select latest record
Thanks in advance

out of thousand records with matched condition i need to select latest recordHow do you determine the "latest" row? From your description it sounds like the following SQL will define the latest:
select max(a_date) from aThis will return the last/latest date used from the table.
Secondly, you now want to select the last row - or rows. As a_date may not be a primary key (you did not state it was and usually a date column make poor choice as unique identifier), there could be more than one row with that "+latest date+".
So to find the latest row(s):
select * from a where a_date = (select max(a_date) from a)Or you could do the following:
declare
latestDate date;
begin
// find the latest date and store it for use and re-use
select max(a_date) into latestDate from a;
// now process the last row(s) - and consider rewriting this
// as a bulk processing loop
for c in (select * from a where a_date = latestDate)
loop
.. do something with the row
end loop;
// now use latestDate variable for some other
// required processing
.. code goes here ...
end;

Latest record need to show in report

Hi all,
I have a requirment on shippment is as below.
I want track a perticulat shippment based on shippment number.
I am loading the shippment details to My ODS and the key's are 'Shippment number' and 'Date' and 'time'.
Now my user don't want to see all the records that are relevent to perticulat shippment in bex report, he wants to see only latest record based on date and time by entering the shippment number only as input in the report.
Can any one advice me on this, Points will be assigned.
Regards,
Raja reddy.

Reddy,
Did you try using a replacement Path variable on Date?
If your req is to show all the shipment no.s for a date which is latest, you can do this by condition as TOPN.
(If date is in KF list)
But if Date is a charecteristic in the Provider, Use repl path and then put TOP N condition on it.
Try it! You must get that.
Cheers,
Sri

Formula to get the latest record

Hi,
I looking to have only the last record logged displayed on my report, can any one help me with the formula ?
Sorry,
Actually to be more precise I'm looking to the latest record for each equipment (where there are many records for the equipment during the day).
Many thanks,
Andreia

Hi,
You could use a SQL Expression field. The following example uses the Northwind database (SQL Server) as an example.
Type the following query in the SQL Expression editor
(SELECT MAX("Orders"."OrderDate")
FROM Orders
WHERE CustomerID = Customers.CustomerID)
Then create a record selection formula:
{Orders.OrderDate} = {%datum}
{%datum} is the sql expression
When you run the report, you will see only the last order for each customer

Select the one record with the latest record

I have the following table called tblSales:
SKU   TransDate   Color
===   ====== ====
123   1/1/2015    Red
123   1/2/2015    Red
123   1/5/2015    Red
123   1/1/2015    White
123   1/2/2015    White
123   1/3/2015    White
123   1/1/2015    Blue
123   1/2/2015    Blue
123   1/5/2015    Blue
I need to create a query along the lines "SELECT the latest record FROM tblSales WHERE Color = 'White''
In this example, the record dated 1/3/2015 would be the result. I know that MAX(TransDate) is used here, but not sure how.
Thanks.
Ken

Karl,
I had already tried that. It returns all 3 records having SKU = 123 and Color = White.
Worst case scenario is I can always search for White 123s using a query with TransDate DESC and then get the first record. I was just hoping for something a bit more elegant.
Thanks for your help though.
Ken

Fetching latest records

Hi All,
I want to fetch some records from a database table which are the latest entries. How can I fetch these records?
Regards,
Jeetu

Hi,
Method 1:
1) check whether you have DATE field in your database table.
2) fetch all records into your internal table.
3) sort internal table by date descending.
4) you will get the latest records on top in your internal table.
Method 2:
If you want only latest 10 records from your internal table
data: begin of itab occurs 10,
Declare your fields here make sure that you have DATE field in your internal table.
end of itab.
Select <fields> from <database table> into itab.
append itab sorted by date.
endselect.
note: Date should be one of teh fields of itab.

Latest record with active flag 'Y' (if only N, select that record)

Hi All,
I am having some records in table emp and need to select one record per id, which meets following criteria:-
(1) if there is only one record for given id, select them. eg- '0154', '0155'
(2) if more than one record then
(2a) select record with active_flag = 'Y'.
(2b) if more than one record with flag 'Y', select latest record where flag = 'Y'. Max eff_date.
Emp table:-
with emp as (
select '0066' id, 'ABC' name, 'Y' active_flag, to_date('01-01-2009', 'dd-mm-yyyy') eff_date from dual union
select '0066', 'PQR', 'N', to_date('01-01-2010', 'dd-mm-yyyy') from dual union
select '0066', 'XYZ', 'N', to_date('01-03-2010', 'dd-mm-yyyy') from dual union
select '0154', 'PQR', 'N', to_date('01-05-2010', 'dd-mm-yyyy') from dual union
select '0155', 'DEF', 'Y', to_date('01-05-2010', 'dd-mm-yyyy') from dual union
select '8686', 'THY', 'N', to_date('01-10-2010', 'dd-mm-yyyy') from dual union
select '8686', 'QWE', 'N', to_date('01-01-2010', 'dd-mm-yyyy') from dual union
select '8686', 'POI', 'Y', to_date('01-04-2010', 'dd-mm-yyyy') from dual union
select '8686', 'MNB', 'Y', to_date('01-03-2010', 'dd-mm-yyyy') from dual
select * from emp;
Output records:-
with emp_selected as (
select '0066' id, 'ABC' name, 'Y' active_flag, to_date('01-01-2009', 'dd-mm-yyyy') eff_date from dual union
select '0154', 'PQR', 'N', to_date('01-05-2010', 'dd-mm-yyyy') from dual union
select '0155', 'DEF', 'Y', to_date('01-05-2010', 'dd-mm-yyyy') from dual union
select '8686', 'POI', 'Y', to_date('01-04-2010', 'dd-mm-yyyy') from dual
select * from emp_selected;Request you to please look at it.

Ritesh

Thanks for posting the sample data and expected resutls in such a useful way. It makes life so much easier.
Assuming that the only valid values in active_flag are Y and N, and that there are no nulls, then this is one way:
SQL > with emp as (
2   select '0066' id, 'ABC' name, 'Y' active_flag, to_date('01-01-2009', 'dd-mm-yyyy') eff_date from dual union
3   select '0066', 'PQR', 'N', to_date('01-01-2010', 'dd-mm-yyyy') from dual union
4   select '0066', 'XYZ', 'N', to_date('01-03-2010', 'dd-mm-yyyy') from dual union
5   select '0154', 'PQR', 'N', to_date('01-05-2010', 'dd-mm-yyyy') from dual union

If there could be values other than Y and N, then use a case statement in the order by to fix the order to give preference to what you want.
For example, if valid values could be Y, N, P and you wanted them selected in that order, then neither ascending nor descending sorts would be right, so you could do something like:
ORDER BY CASE active_flag WHEN 'Y' THEN 1
                          WHEN 'N' THEN 2
                          WHEN 'P' THEN 3

Returning latest records based on specific conditions

Hi Everyone, Thanks for everyone response for my queries. All responses are highly appreciated. I need one help in developing Sql query. I am
using Oracle 11.2.
I have table Test as below having columns as, ID;Name;Position;Level;Date_Added;Flag_Name;
Suppose I have below data in table:
ID       Name      Position      Level              Date_Added                Flag_Name
1       Jack       Manager        10         10/29/2013 11:00:00 PM          Match
2       Tom        Supervisor     20            10/31/2013 9:00:00 AM       NoMatch
1       Jack       Manager        15          11/1/2013 10:00:00 AM          Error
1       Jack       Manager        20         10/1/2013 9:00:00 AM           NoMatch
3       John       Salesman      5           10/4/2013 2:00:00 PM           Error
1       Jack       Manager        17         9/28/2013 2:00:00 AM           NoMatch
2       Tom        Supervisor     12         11/2/2013 10:00:00 AM          NoMatch

4       Remy       Accountant     19         11/3/2013 2:00:00 AM           Error
2       Tom        Supervisor     10            10/29/2013 7:00:00 PM           Error
I need to return latest data in query based on combination of (ID;Name;Position) and date range with below conditions:
1) Need to return latest records for Flag_Name other than Match.
2) If latest record for combination of (ID;Name;Position) will come with Flag_Name as Error in that specified date range, then we need to look for this combination has Flag_Name as NoMatch anywhere before in table.
3) If Flag_Name as NoMatch is found for this, then we need to return it. In this case also, if we found multiple records with Flag_Name as NoMatch for combination of (ID;Name;Position), then we need to return latest one.
4) Else we find no record for combination of (ID;Name;Position) with Flag_Name as NoMatch in table, then we can return the latest record with Flag_Name as Error.
While select ID;Name;Position should be unique combination, as we always return latest data for it.
As per above table, if I need to return data for date range between 29-Oct-2013 and 5-Nov-2013, expected result will be like below:
ID       Name      Position      Level         Date_Added                      Flag_Name
1       Jack       Manager        20              10/1/2013 9:00:00 AM           NoMatch
2       Tom        Supervisor     12             11/2/2013 10:00:00 AM          NoMatch
3       John       Salesman        5              10/4/2013 2:00:00 PM           Error
4       Remy       Accountant     12           11/4/2013 1:00:00 PM           Error
Please let me know if anyone has any doubt about the logic. Is it possible if we can do it in select statement rather than pl/sql code?
All comments/suggestions will be highly appreciated.
Thanks in advance.

How to get only the latest record in a folder

Hi all,
We have an OA SIT that is not a "standard" SIT in that it does not have the traditional Begin and End date. It only has an Effective date. Is there some way I can filter this table to only give me the latest record in the series? I know how to do this in SQL, but don't see how it would be possible in the EUL.
We're trying to avoid creating database views, but at this point, I'm thinking it may be the easiest way to address this. Any other suggestions?
Thanks in advance,
Jewell

Jewell.
Of course I'm not going to mention that I have no idea what a 'standard' SIT is compared to your basic 'non-standard' SIT ... and I have to watch my spelling of such ... but however ...
As you're most likely aware, in SQL you would get all the 'standard' SIT records first by going through the table. Then you'd go back through them all and find the most recent one.
Because of this 2 table pass, I agree that just putting the SQL code in a custom folder (as you're not using views) would make the most sense.

Query to find 10 latest records

hi all,
i have 100 records with following attributes.
username
mobile no
date
i want to select 10 latest rocords for a perticular mobile no(based on date attribute).
regards,
uttam

Hi Mohan,
I would use the same analytic function to get the records. However, I will have to modify the expression to get the records starting from the latest date as posted by Uttam. I just added the option DESC to start from the latest record and run down to the earliest.
select * from(
select username, mobile_no, date,
rank() over(partition by mobile_no order by date DESC) rn
from tabl1)
WHERE rn<=10;

Latest record
