Date tracking in oracle

Hello all,
I'm good in sql but whenever it comes to date tracking, i'm always confused. I struggle a lot. Not sure why but there will be lot of scenarios in date tracking. How to logically resolve the date tracking issues in sql.
Any advice is appreciated.

Date tracking in Oracle HRMS

Hello,
in PER_ALL_ASSIGNMENTS_F AND PER_ALL_PEOPLE_F and other data tracked tables, is there any way to find out when a new record is going to be inserted and when an existing record is updated? For example when a job of a person is changed, a new assignment record is added. Similarly at what circumstances these date tracked tables are changed? Is there any document to find out a way to figure out?
Thanks a lot in advance.

Hi,
If I understand you correctly ypu want some npiece of code which does this checking for you and takes proper action.
There is a specific api DT_API which helps you do that.
I am posting a piece of code from that API (Spec from 11.5.10 instance)
dt_api.find_dt_upd_modes_and_dates
( p_effective_date                in     date
,p_base_table_name               in     varchar2
,p_base_key_column               in     varchar2
,p_base_key_value                in     number
,p_correction                       out nocopy boolean
,p_update                           out nocopy boolean
,p_update_override                  out nocopy boolean
,p_update_change_insert             out nocopy boolean
,p_correction_start_date            out nocopy date
,p_correction_end_date              out nocopy date
,p_update_start_date                out nocopy date
,p_update_end_date                  out nocopy date
,p_override_start_date              out nocopy date
,p_override_end_date                out nocopy date
,p_upd_chg_start_date                out nocopy date
,p_upd_chg_end_date                  out nocopy date
)Now there are numerous boolean variables and based on their values the action gets decoded.
For example if you want to check for a record started on 01-JAn-2012 and you want to check what will be mode on 01-SEP-2012 then
p_effective_date := '01-SEP-2012'
p_base_table_name := 'PER_ALL_PEOPLE_F'
p_base_key_column := 'PERSON_ID'
p_base_key_value := 1234
where 1234 is value of person_id.
IF ( p_update_override = TRUE OR p_update_change_insert = TRUE )
    THEN
        -- UPDATE_OVERRIDE
        gc_dt_ud_mode := gc_upd_override; -- UPDATE OVERRIDE
    END IF;
    IF (p_correction = TRUE )
    THEN
        -- CORRECTION
        gc_dt_ud_mode := gc_correction; -- Correction
    END IF;
    IF (p_update = TRUE )
    THEN
        -- UPDATE
        gc_dt_ud_mode := gc_update; -- UPDATE
    END IF;

Date Track history tables in Oracle HRMS & Discoverer

Hello experts,
I will be glad if anyone can help thru. I am trying to develop the DIS report for Audit purpose that tracks all the changes entered by Data Entry clerks, regardless of effective date. Mainly from Person Form and Assignment Form.
Is there anyway I can include the exact date/time the change made/status updated. Is the 'Effective date' clue?
e.g. There is an Assignment Change - from 'Global Operations' organization to 'Domestic Application' organization. The change is suppose to be effective from 05/02/2011 but I am entering the action on 04/18/2011. Similar for past events - if I make date tracked Assignment change suppose to be effective from 04/04/2011.
How can I accommodate this in a report. I just have EUL rights of Discoverer10g. (Oracle R12)
Thanks a lot.

Hello
The effective date is used for date tracking, but not to determine when a change was made. To determine when a change was made you need to look at the date last updated. Bear in mind though that only tables which can be updated have this field. If a table is only used for inserts then you will not find this field.
The effective dates are used to tie records in different tables together. Some tables have just an effective date, some have an effective start and an effective end, while others have a FROM date and a TO date. All of these can be used together to determine the state of play as it was at a certain point in time. The current records can have their effective dates compared to SYSDATE like this:
EFFECTIVE_START_DATE <= SYSDATE and EFFECTIVE_END_DATE >= SYSDATE
Records from one table can be tied to records in another to ensure for example that an assignment is tied correctly back to the right person record. In this case you would need to make sure that the effective date on the assignment is greater than or equal to the effective start date of the PERSON and less than or equal to the effective end date.
Date last updated will be used to determine exactly when a record was updated. Sometimes a date last updated will pre-date an effective date when companies enter records in advance of when they will be active. For example, in payroll where it is very common to enter new salaries many weeks in advance or in your situation where a change is supposed to be effective from 05/02/2011 but is entered on 04/18/2011. In this case the date last updated will say 04/18/2011 and the effective date or effective start date, depending which is in use, will have 05/02.2011. The effective date, effective start date and date from should never change and should always reflect a record's effectiveness, regardless of many times the record gets updated. The effective end and from dates will be updated to a real date a new record is added and sometimes these will be NULL so you have to take that into account too.
Data warehouses will generally load data based on the date last updated so that, for example, all records updated in the last 24 hours can be selected.
Hope this helps

What is the best way to put LabVIEW DSC data into an Oracle database?

I have been collecting data using LabVIEW DSC 7.0 for several years and have always accessed the data from the Citadel database via the Historical Data Viewer. I would now like to begin putting this data into an Oracle database. My company stores all their data in Oracle and it would provide me all the benefits of their existing infrastructure such as automated backups, data mining tools, etc.
My initial thought is to use "Read Trace.vi" in LabVIEW to pull historical data from the citadel database at regular intervals (e.g. 1 minute) and insert this data into Oracle via ODBC. In this way, I do not need to track the value changes in order to know when to write to Oracle. I also considered replicating the citadel database using some other method, but I recall that the tables used by citadel are somewhat complicated. I only need a simple table with columns for channel, timestamp, and data. The "Read Trace.vi" will provide me data in this format.
I do not need to update the Oracle database in real time, a few minute delay is acceptable. If anyone has a better idea or additional insight please let me know. Thanks.

In terms of connectivity, you want to use ADO, not ODBC. Beyond that, it all depends on the structure of the data and what you are going to want to do with it. This is a very big question that you need to be getting some in-depth assistance.

What is the purpose of Date From and Date To In Oracle HRMS ?

hi
I have doubt on
What is the purpose of Date From and Date To In Oracle HRMS?
Thanks

Where do you see these fields? Please give full details (eg, the navigation path).
If you're referring to Effective Start Date and Effective End Date (effective_start_date, effective_end_date) these are two fields that appear on many HRMS entities. They're used to store dated history over time. For example:
14-Jan-2009 to 19-Apr-2009 - Pam Stephens
20-Apr-2009 to date - Pam Erickson
In this example Pam got married on the 20th April 2009 and changed her surname from Stephens to Erickson. Here the history of changes are kept so that if we date-track to any time prior to the 20th April 2009 we'll see Pam Stephens and if we date-track on or after the 20th April 2009 we'll see Pam Erickson.
Check out the following Oracle Support article for more information:

View of Date track history change field summary

Hi experts,
In Oracle HRMS, we have the function "Date Track History" in People/assignment. In the summary window of Date Track history, we have column which is named "Change Field Summary". For reporting purpose, I am looking for the view/function/package/... which can show type of data.
For example:
- If I give certain assignment number/assignment id, view/function can return "Birth Date, Full Name, Known As" in "Change Field Summary".
Thanks in advance.

Hi Vigneswar,
Thanks for reponse.
The view PER_ASSIGNMENT_HISTORY_VIEW shows data changes in columns, it is similiar with HRFV_PERSON_ASSIGNMENT_HISTORY view. However It does not show us which columns were changed like in "Date track history change field summary" window. I don't have access to Unix server, so that I can't do the trace stuff.
Thanks and Regards,
Hieu

Assignment Date Track History-Changed Field Summary

Hi all,
We have Oracle HR 11.5.7 FP.G.
In the HRMS there is a for the Employee's Assignment Date Track History showing the Changed Field Summary.
We want to specify the exact field(s) changed in Assignment for a period using SQL or Discoverer for Reporting Purposes.
Does anyone have any sample coding or idea on how to perform this?That is to specify exactly what fields changed in an assignment change.
What I can think of is to compare values but I'm not sure how I can get the desired result.
I would appreciate any feedback.
Thanking you in advance
Elena

Elena,
To meet you're requirement: changes per person during a period
- done this before using audit trail, be aware that the reports that comes out standard, does not resemble anything a HR user can read. Quite often it says this ID has change to that ID. Building a reports that changes this into something meaning full for a HR/Payroll person does require a considerable effort.
- using the change event log (system extract) or the retro notification report (payroll) will give you're results in a better format. Problem you may encounter here, is that not all entities are available (by default). You may have to add some dynamic triggers.
- if you want to understand how the datetrack functionality is deriving the data, this paper on metalink may help : Create and Modify DateTrack History Views Note:177734.1

Data Tracking

I found out there is a great possibility to keep the history of changes to data in tables, using version-enabled tables with Workspace Manager. However; we have been suggested to use date tracking logic incorporated in the EBS HR modules.
What is the difference between the two ? Is one way better then the other ? Has someone experience using one of the two and tell me about the pros and the cons of the solution?
Thanks,
Bart

I'm not familiar with any change logics of EBS, but as always if it's built in (and known, tried, etc) you should compare the cost of using that and the cost of building, maintaining and supporting your own Workspace objects to do the same thing. Also, does EBS has the capabilities you need and want?

Doubt in Date tracking update of person records

Dear all,
I have a doubt on the approach to be followed for a particular scenario. The following is the explanation:
Let us say we have a person record as follows:
Employee_No      Effective start Date         Marital status
100                    01-Jan-2000                  Single
Let us say HR user date tracked to 01-Jan-2010 and updated to Married
So we have the following :
Employee_No      Effective start Date    Effective end date      Marital status
100                    01-Jan-2000                31-Dec-2009            Single
100                    01-Jan-2010                31-Dec-4712            Married
Later HR found that the date of updation was not correct it should be 01-Jan-2011, which was wrongly entered as 01-Jan-2010.
Now should the HR
1) Go to the earliest record and delete the next change and then re enter with correct date? or
2) Go to 01-Jan-2010 , Correct the record to Single, go to 01-Jan-2011 update to Married.
Because Oracle allows both. In the second case, per_all_people_f will have 2 records with the same set of data but with different start and end dates.
Can any body say which is correct approach and why?
Thanks
Raj

Hi Raj,
In terms of business both the actions will fine as in reports it will show the same result.
From technical (data level) It is your decision on the way you want to go ahead.
In case of a error it is better practice to purge the next changes and update the record with correct details.
Thanks,
Sanjay

Problem with date format from Oracle DB

Hi,
I am facing a problem with date fields from Oracle DB sources. The date format of the field in DB table is 'Date base type is DATE and DDIC type is DATS'.
I mapped the date fields to Date characters in BI. Now the data that comes to PSA is in weird format. It shows like -0.PR.09-A
I have changing the field settings in DataSource to internal and external and also i have tried mapping these date fields to text fields with out luck. All delivers the same format.
I have also tried using conversion routines like, CONVERSION_EXIT_IDATE_INPUT to change format. It also delivers me the same old result.
If anybody of you have any suggestions or if anybody have you experienced such probelms, Please share your experience with me.
Thanks in advance.
Regards
Varada

Thanks for all your reply. I can only the solutions creating view in database. I want some solution to be done in BI. I appreciate if some of you have idea in it.
The issue again in detail
I am facing an issue with date fields from oracle data. The data that is sent from Oracle is in the format is -0.AR.04-M. I am able to convert this date in BI with conversion routine in BI into format 04-MAR-0.
The problem is, I am getting data of length 10 (Output format) in the format -0.AR.04-M where the month is not in numericals. Since it is in text it is taking one character spacing more.
I have tried in different ways to convert and increased the length in BI, the result is same. I am wondering if we can change the date format in database.
I am in puzzle with the this date format. I have checked other Oracle DB connections data for date fields in BI, they get data in the format 20.081.031 which will allow to convert this in BI. Only from the system i am trying creating a problem.

When attempting to view the date track history for one employee, errors out

Hi All
When I attempt to view the date track history for one employee, it gives errors.
To get the details, the navigation is :
1. Search for employee xxxxxx
2. click on Assignment button
3. click on Date Track History.
4. Receive error APP-DT-52554.
5. Click OK on error message
6. click on Full History button.
7. Receive error APP-PAY-06153
What could be the problem and how to solve this?
Regards
Rahman

Sounds as if there is an inconsistency with the date tracked records. Can you check the records through TOAD or SQL Plus?
Have alook at MetaLInk article 343070.1 which refers to the second error message.

Using Web Service as Data source (Pluggable Data Source) in Oracle Reports

Anyone using Webservice as a pluggable data source in oracle 10g reports.(Report builder version:10.1.2.0.2)? We need to be able to use web service as one of the data source to create reports.Tried the following and ran into issues:
Imported the wspds.jar fle from oracle plugin exchage. When tried using it received the following error in oracle reports trace file.
04/26 22:27:22 java.lang.NoSuchMethodError: oracle.xml.parser.schema.XSDBuilder.build([Loracle/xml/parser/v2/XMLDocument;Ljava/net/URL;)Ljava/lang/Object;
By troubleshooting issue found out that xmlparserv2.jar in 10g is newer than xmlparserv2.jar in 9i. wspds.jar is using xmlparserv2.jar in 9i as it was developed and tested for 9i only. Believe there is no newer wspds.jar file developed specifically for 10g?
Is there a better/standard solution to use webservice as data source in oracle 10g reports? Does later version of oracle reports supports webservice as a data source without any additional plugins? Any suggestion would be helpful.

Please provide support for the above request.
It appears that Oracle 10g reports doesn't support Web Service as pluggable data source. Is this option is available in Oracle 11g Reports or Oracle Discoverer Or OBIEE?

How can i save the data from the Oracle database to my local directory

How can i save the data from the Oracle database to my local directory instead Of saving the data file to the Directory created on the Oracle Server ?
I require to design the Procedure which will pull the data from various tables and needs to store the data in the Client's local directory.

Since SQL*PLUS runs on the client, you can use SQL*PLUS to spool data to your local drive.
You could also use the database to write a a specified drive where all users have access to (mapped network drive, e.g.). I wouldn't recommend doing it that way, but it is sometimes useful when the files are created in some nightly batch run.
