Find the latest updated or the latest inserted record in a table

Hi All,
Thanks in advance
Just a simple question
How do we find the latest updated or the latest inserted record in a table ?
Provide some queries in SQL?

You can order by rowid desc to get lately inserted records, but I'm not sure about updated records.That is incorrect, Oracle might use old rowid's even in inserts and you cannot assure that the max(rowid) refers to the latest record.
If the table is created with rowdependencies one can use ORA_ROWSCN pseudo column to check on date/time when the last dml has been performed over that table. But, that has some limitations too, Old snapshots will be erased hence one can check the last dml with a time frame of few days.

Get the latest date record in Query

Hi, Expert:
Please help on this:
The requirement is to get the the latest date record in Query. For example:
Data in provider:
Plant          date            amount
A01         2007/04/08      30
A01         2007/06/09      70
A01         2007/12/08      30
we only want the query display:
A01         2007/12/08      30
I have tried exception aggregation, but it does not work. Any ideas are highly appreciated.

Or you can model the date as a key figure after 0date_kyf and set aggregation to max, you'll get something like
select plant, amount, max(date) from ... group by plant, amount
used it for inventory reporting (materials and their last movement date, days from the last movement etc.) and worked well.

How to get only latest Updated Record in OBIEE answers
Thanks&regards

HI,
agg function last doesn't help?
If not, create a new column upd_date in your database table and with triggers update it with sysdate.
Add it in repository, map it with max() function and then filter your data where upd_date = that max() column...
Or in presentation create an report that uses only that max() column and your report filter based on other report (that report)...
Haven't tried but I think it will work....
Hope It helps...

Fetching latest active records

Hi,
I have a scenario to take only the latest date record for each key column value (ID column). But the latest segment should not be a deleted one. Hereby i am providing an example of my input details and required output values. Thanks in advance!
Type O = Created
Type R = Updated
Type S = Deleted
CREATE TABLE #T (ID VARCHAR(16), SEGMENT INT, STYPE VARCHAR(1), Eff_dt Date)
INSERT INTO #T VALUES ('101',1,'O','2013-07-01')
INSERT INTO #T VALUES ('101',1,'S','2013-07-01')
INSERT INTO #T VALUES ('102',1,'O','2013-06-15')
INSERT INTO #T VALUES ('102',1,'S','2013-06-15')
INSERT INTO #T VALUES ('102',2,'O','2013-06-19')
INSERT INTO #T VALUES ('102',2,'R','2013-06-20')
INSERT INTO #T VALUES ('103',1,'O','2013-01-01')
INSERT INTO #T VALUES ('103',1,'R','2013-01-06')
INSERT INTO #T VALUES ('103',1,'R','2013-11-23')
SELECT * FROM #T
DROP TABLE #T
In the above example, the output should be
1.) The ID '101' should be ignored as it is created and deleted on the same date (which is latest date for ID 101)
2.) The ID '102' , Segment 2 value should be come as output, because Segment 1 is deleted earlier and segment 2 is created and updated recently.
3.) The ID '103' for 2013-11-23 should be come as this is the latest one and its not deleted.
I am attaching the expected output for my requirement.

Fazlu

Hi,
Thanks for your reply. But its not corrct for my scenario. As i said, ID '101' should not come in output as it is Created and Deleted on same day, I also tried your query, but it s fetching 101, which is not correct one for my situation.
If we took max day for each ID, 101 will have 2 values, which is both open and closed record, if same Segment is open and closed on same day, i should not consider that ID at all.
Regards,
Fazlu
Ok
what about this?
SELECT ID,SEGMENT,STYPE,Eff_dt
FROM
SELECT *,
DENSE_RANK() OVER (PARTITION BY ID ORDER BY Eff_dt DESC) AS Seq
FROM #T
)t
WHERE Seq = 1
GROUP BY ID,SEGMENT,STYPE,Eff_dt
HAVING SUM(CASE WHEN STYPE = 'S' THEN 1 ELSE 0 END)=0

Making system to use the latest Infotype Record for the Current Period

Hello,
I would like to know how the system behave if there is a record modified in the middle of the Pay Period, which record would the PY schema use? Ex: in IT0009 EE has selected multiple Bank Transfer. He say 100$ Bank 1 and Rest to Bank 2. In the middle if the Pay period, the EE comes and makes changes to his Bank Transfer, as he closed the account in Bank1, he creates new Bank and transfers 100$. Now when the PY run, it think both Banks (Bank1 prev and Bank 1 current ) are valid and tries to send 100$ to each back and sends rest to Bank2. Which is not correct. This issue happens when someone changes their record in the middle of the period. So It is assumed to change the process to not to change in the middle of the period. It has to be effecting of 1st of next period.
But I want to check is there anyway we can make the system to use the latest one if it finds multiple record for the same period?
any suggestion please.
Thank you.
Raj

Hi Donnie,
This system actually delimits the previous record but since the change is happened in the middle of the period, but record are considered as active.
For Ex: The Pay Period is 01/01/2009 to 01/15/2009 and There was a record for Bank1 for that period and user comes and creates a new record on 01/05/2009 for Bank1. Now for this payperiod since its with the period both records are becoming active. So system uses both the records and deducts. Hope you get what I'm saying.
Thanks,
Raj

Report the latest event (record) for a device

I could have sworn I had this one working before but for the life of me I cant remember how I did it and I cant seem to figure it out anew.
I'm tracking events per device. A device may have any number of events in a given time period. I need to track the MOST RECENT event for a device per device. I do not want to have multiple records per device, only the record with the MOST RECENT timestamp.
I made the following two attempts but I'm still getting nowhere.
select
device,
MAX(dt) KEEP (DENSE_RANK FIRST ORDER BY dt) as time_Var
from db_table partition (pPname)
where
    Lower(example) like '%example text%'
    and dt > sysdate - 5and
select DISTINCT
device,
       (select TO_CHAR( (MAX(table_name.dt)), 'HH24:MI:SS MM/DD/YYYY') "timeVar"
          from table_name partition (pPName)
          where
       Lower(Example) like '%example text%'
       and dt > sysdate - 5)
from table_name partition (pPName)
where
    Lower(Example) like '%example text%'
    and dt > sysdate - 5
order by device Asc;

Hi,
Salim's solution with
KEEP (DENSE_RANK FIRST ORDER BY dt)will show you the least recent event in the last 5 days.
If you want the most recent event, change "FIRST" to "LAST"
KEEP (DENSE_RANK LAST ORDER BY dt)or sort in DESCending order:
KEEP (DENSE_RANK FIRST ORDER BY dt DESC)If you want to display several columns from the most recent row, you'll have to use KEEP (DENSE_RANK ...) on each of them (except device).
In that case, you might find it easier to use an analytic function, such as ROW_NUMBER:
WITH     ranked_data AS
     SELECT     device, column_a, column_b, column_c
     ,     ROW_NUMBER () OVER ( PARTITION BY device
                               ORDER BY         dt     DESC
                       ) AS r_num
     FROM     your_table
     WHERE     LOWER (example)      LIKE '%example text%'
     AND     dt               > SYSDATE - 5
SELECT device, column_a, column_b, column_c
FROM     ranked_data
WHERE     r_num   = 1;

Problem in fetching the latest updated record.

Hello ,
I have a program in which i am creating a BDC session and submit the same in program rsbdcsub, now the problem is that i need to capture the Field Qstate from the table APQI, its not updated instantaneously, so i am not able to get the latest value of QSTATE from updated APQI table,
I have used commit work, commit work and wait , SET UPDATE TASK LOCAL, nothing is working, only if i put wait up to '1.5' seconds before fetching the value from table APQI i get the updated Qstate, but this will create a performance issue so please suggest.
Can any one please help me resolve this problem.
Regards,
Abhinav

it's quite normal that status is updated after the job is modified
and you cannot know beforehand how much time it will take to do it (even the start time is not sure because it could be delayed !)
you could select the value until it is one of a list that you expect (for example, finished or cancelled)

Varchar to Datetime conversion and selecting latest datead records

Hi:
I've a table as below:
ActionDate|Status|Name
23/10/2012|Block|James
24/10/2012|Open|James
25/10/2012|Block|James
20/09/2012|Block|Tanya
17/09/2012|Block|Fox
18/09/2012|Open|Fox
27/08/2012|Block|Martin
27/08/2012|Open|Martin
Desired Output is as follows:
ActionDate|Status|Name
25/10/2012|Block|James
20/09/2012|Block|Tanya
Select those records only which has Block staus on most recent date. It will also eliminate those which has Open status on the same date.
One more problem is the ActionDate field is actually Varchar2 type and there are mismatch as well. For example: some of those are in MM/DD/YYYY and
some are in DD/MM/YYYY
So, how can I convert these strings into formated date and make the desired output in a single query. Please let me know.
Thanks/Tanvir

Select those records only which has Block staus on most recent date. It will also eliminate those which has Open status on the same date.
One more problem is the ActionDate field is actually Varchar2 type That's not a very good idea. This problem shows just one of the many reasons why you should always use DATE columns for date information.
and there are mismatch as well. For example: some of those are in MM/DD/YYYY and
some are in DD/MM/YYYYThe you have no way of knowing if '01/12/2012' means January 12 or December 1. The query below arbitrarily assumes that will be December 1.
So, how can I convert these strings into formated date and make the desired output in a single query. Please let me know.

I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as INSERT) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Select latest two records per group

hi there,
i've been googling around and still can't really find an appropriate solution to retrieve two most recent records per group in one sql. Is this even possible?
Let's say there is a MyLife table :
ID, Event , RecordedDate
1. 1, 'Fell down the stairs', '20-DEC-07'
2. 1, 'Fell down the stairs', '22-DEC-07'
3. 1, 'Fell down the stairs', '23-DEC-07'
4. 2, 'Tried to kiss santa', '23-DEC-07'
5. 3, 'Reindeer stolen', '24-DEC-07'
6. 4, 'Chimney Broke', '25-DEC-07'
Output should be :
2. 1, 'Fell down the stairs', '22-DEC-07'
3. 1, 'Fell down the stairs', '23-DEC-07'
4. 2, 'Tried to kiss santa', '23-DEC-07'
5. 3, 'Reindeer stolen', '24-DEC-07'
6. 4, 'Chimney Broke', '25-DEC-07'

I believe that something along these lines would be portable to most other databases.
SQL> SELECT id, event, recordeddate

How to get the latest ALV record?

Hi all,
I have create a ALV in my module pool with delete row feature. The module pool is able to display the record into the ALV.
The user needs to delete some of the unwanted records. After that, my program needs to populate the record (after deleted rows), and save it into a customized table.
My question is, how can I get the most up-to-date record from the ALV and assign it into internal table?
Thanks in advance.

Hi,
Yes, I am using OOPs ALV
I have included this code into PAI, but how do I get it assigns to a internal table?
data: lv_valid type c,
      lv_refresh type c.
call method grid1->check_changed_data
importing
    e_valid = lv_valid
changing
    c_refresh = lv_refresh.
PBO
data grid1 type ref to cl_gui_alv_grid.
call method grid1->set_table_for_first_display
    exporting
      i_structure_name     = 'ZSTRUCTURE_EXCEL'
      it_toolbar_excluding = lt_exclude
      is_layout            = ls_layout
    changing
      it_outtab            = gt_export2excel.
FYI, my ALV is with delete row feature, the user will delete some of the row and now I need to get the remaining row and assign it to an internal table.
Please help with some sample code. Thanks.

Cross Join Records - only want the "latest valid" records depending on Shop-Level

Hi everyone,
I have a problem with the cross join for my retail application.
Initial Situation:
There are several Shops and in also several products. Usually the products are just created on global level so that all shops can access and sell them.
BUT there is a feature, that single shops can create derivations of articles to change some settings for them (e.g. a the price of a certain handy is global 90€ but in one flagship store the price is 80€).
Sample Tables
create table shops(
id number,
name varchar2(64) not null,
hierarchy varchar2(64) not null,
parent number,
PRIMARY KEY (id));
create table articles(
id number,
name varchar2(64) not null,
price number,
shop_id number not null,
PRIMARY KEY (id));
-- create 4 shops with the hierarchy
- Global
    |- Shop A
    |- Shop B
          |- Shop B.1
insert into shops values (0, 'Global', '.0.', null);
insert into shops values (1, 'Shop A', '.0.1.', 0);
insert into shops values (2, 'Shop B', '.0.2.', 0);
insert into shops values (3, 'Shop B.1', '.0.2.3.', 2);
-- insert some articles + derive the 'Article 2' for shop B.1
insert into articles values (0, 'Article 1', 100, 0);
insert into articles values (1, 'Article 2', 90, 0);
insert into articles values (2, 'Article 2', 80, 3); -- derive article 2 for the shop 2 and set price to 80 instead of 90
Sample Statements
-- restrict to 'Article 1' where no derivations exists
select s.*, a.*
from shops s, articles a
where s.hierarchy like '%.' || a.shop_id || '.%' -- ensures that derivations only appear at the level of the shop and not for each shop
and a.name = 'Article 1';
The result gets the one article for each shop. So I have no problem to restrict to a shop id, and getting the article even if it's not created for that shop level.

select s.*, a.*
from shops s, articles a
where s.hierarchy like '%.' || a.shop_id || '.%' -- ensures that derivations only appear at the level of the shop and not for each shop
and a.name = 'Article 2';
The result of this statement shows, that the "Article 2" is contained two times for the ShopID 3. This is because the Article exists two times in the articles table.

Problem1
The last result shows my problem very well. I just want to get the highest level of article if there are any derivations.
Problem2
The solution must be very fast, because I have about
3.000 Shops and about
700.000 different Articles (on global level)
Can somebody help my to find a performant solution for my problem?

Hi,
In the output for 'Article 2', do you really want prices of 100 and 65? I assume you meant 90 and 80, like this:
                                                           ARTICLE
SHOP SHOP                         ARTICLE ARTICLE          _SHOP
_ID _NAME      HIERARCHY PARENT _ID     _NAME      PRICE _ID
   0 Global     .0.               1       2          90    0
   1 Shop A     .0.1.           0 1       2          90    0
   2 Shop B     .0.2.           0 1       2          90    0
   3 Shop B.1   .0.2.3.         2 2       2          80    3
Here's how I got the output above:
WITH   joined_data     AS
    SELECT    s.id      AS shop_id
    ,         s.name    AS shop_name

    ,         s.parent
    ,         a.id AS article_id
    ,         a.name AS article_name
    ,         a.price
    ,         a.shop_id AS article_shop_id
    FROM             shops     s
    LEFT OUTER JOIN articles a ON   a.shop_id = s.id
                                  AND a.name     = 'Article 2' -- or whatever
SELECT    shop_id
,         shop_name
,         hierarchy
,         parent
,         REGEXP_SUBSTR ( SYS_CONNECT_BY_PATH (article_id, '/')
                        , '(\d+)/*$'
                        , 1, 1, NULL, 1
                        )    AS article_id
,         REGEXP_SUBSTR ( SYS_CONNECT_BY_PATH (article_name, '/')
                        , '(\d+)/*$'
                        , 1, 1, NULL, 1
                        )    AS article_name
,         REGEXP_SUBSTR ( SYS_CONNECT_BY_PATH (price, '/')
                        , '(\d+)/*$'
                        , 1, 1, NULL, 1
                        )    AS price

                        , '(\d+)/*$'
                        , 1, 1, NULL, 1
                        )    AS article_shop_id
FROM      joined_data
START WITH parent IS NULL
CONNECT BY parent = PRIOR shop_id
Like everything else in Oracle, it depends on your version.
I used '/' as a delimiter, assuming that character never occurs in the article_name, article_id, price or shop_id. If '/' can occur in any of those columns, you can use any other character as a delimiter. You don't have to use the same delimiter for all 4 columns, but remember to use the same delimiter in REGEXP_SUBSTR that you use in its nested SYS_CONNECT_BY_PATH.
Instead of doing 4 very similar REGEXP_SUBSTR (SYS_CONNECT_BY_PATH ... ) calls, you could do just 1, for article_id, and then join to the articles table to get the other columns. I suspect that the way I posted above is faster.
