Poller DB to select records based on the timestamp
Hi all
I want select records from the coloumn timestamp where the timestamp is older than an hour. Is it possible to do this through poller db? I tried but unable to pass the dynamic value (currently - 1 hr)
Thanks in advance!
Eventually create a view based on the timestamp and singled out the dbpoller view.

Select records based on the monthly anniversary date
Hello
I have a table with a field of date_added and I want to select records from monthly birthday of this field.
for example. ID, Date_added
1, DECEMBER 10, 2012
2, 11 NOVEMBER 2012
3, 10 MARCH 2012
4, FEBRUARY 28, 2012
5, 30 DECEMBER 2012
So for January 10, 2013, I would like to return the documents 1 and 3 only
I started watching the extract function, but this little falls down to the records at the end of the month. For example, on 28 February, I also include records where 29, 30 or 31 is the day of date_added. So, in the above table, I won't return documents 4 and 5, but retrieves only returns 4.
Is there a simple function to make the request of birthday this month - have I missed something very obvious? Or I have to write a query to explicitly dates at the end of the month? So far I have not found a reasonable solution!
I use 11g
Thank youuser11259857 wrote:
Hi Al,.No I don't think that there is a flaw. For example, the 30 Jan is not the last day of the month, but is June 30. Thus, on 30 January I want only to interrogate all the dates falling on the 30th - 28 February, after already being interrogated on the 28 Jan. However, on 30 June, I would query the 30th of each month, as well as the 31 January, March, may, July, Aug, Oct, dec. February is a special case, being both shorter and a leap year
Thank you

Hi Richard,
so, we can assume that your needs are:
If the day is the last day of that month, interview the day of the other months being > = day of the current month.
That is to say:
Jan-30 = query only 30 other months
Jan-31 = query only 31 of the other monthsFeb-28 (non-leap years) = question 28, 29, 30 and 31 other months
29 February (leap year) = query 29,30,31 to other monthsMar-30 = query only 30 other months
Apr-30 = query 30 and 31 other monthsThis hypothesis is correct?
If so, then something like this should work:
WITH mydates(id, date_added) AS ( SELECT 1, TO_DATE('10-DEC-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL SELECT 2, TO_DATE('11-NOV-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL SELECT 3, TO_DATE('10-MAR-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL SELECT 4, TO_DATE('28-FEB-2012', 'DD-MON-YYYY') FROM DUAL UNION ALL SELECT 5, TO_DATE('30-DEC-2012', 'DD-MON-YYYY') FROM DUAL ) SELECT id, date_added FROM mydates WHERE (:input_date = LAST_DAY(:input_date) AND TO_CHAR(:input_date,'DD') <= TO_CHAR(date_added, 'DD')) OR TO_CHAR(:input_date,'DD') = TO_CHAR(date_added, 'DD'); with input_date = 28/02/2013 id date_added 4 28/02/2012 5 30/12/2012Kind regards.

Hello
You can use the ROW_NUMBER analytic function.
I don't have a copy of your table, so I'll use scott.emp to illustrate. In scott.emp, there may be several lines for a single job. To display only 1 row per job, hiredate line with the most recent:
WITH got_r_num AS
(
SELECT empno, hiredate-, deptno, job or whatever columns you want
ROW_NUMBER () taken OVER (PARTITION OF work
ORDER BY hiredate DESC
) AS r_num
FROM scott.emp
-WHERE--if you need a filter put it here
)
SELECT *- or the list of all columns except r_num
OF got_r_num
WHERE r_num = 1
;
What results do you want in the case of links? Depending on your needs, you can add expressions of tiebreaker to the analytical ORDER BY clause or the use of RANK instead of ROW_NUMBER.
I hope that answers your question.
If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.
If you change the query at all, post your modified version.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).See the FAQ forum: https://forums.oracle.com/message/9362002

Delete records based on the foreign keys of oracle 11 g
I have a requirement to remove the records from the tables in the order according to
the existing foreign keys.
I for example, the following tables and the pk, fk constraints:
create table one
(aa number (1),)
descr varchar2 (20));
ALTER table one
Add constraint a_pk key (aa) primary;
create table b
(aa number (1),)
descr varchar2 (20));
ALTER table b
Add constraint b_pk key (aa) primary;
create table c
(aa number (1),)
descr varchar2 (20));
ALTER table c
Add constraint c_pk key (aa) primary;
create table a2
(aa number (2),)
id_aa number (1).
descr varchar2 (20));
ALTER table a2
Add constraint a2_pk key (aa) primary;
ALTER table a2
Add constraint a2_fk foreign key (id_aa)
references a (aa);
create table b2
(aa number (2),)
id_aa number (1).
descr varchar2 (20));
ALTER table b2
Add constraint b2_pk key (aa) primary;
ALTER table b2
Add constraint b2_fk foreign key (id_aa)
references b (aa);
create table z
(aa number (3),)
id_aa number (1).
id_bb number (1).
descr varchar (20));
ALTER table z
Add constraint z_pk key (aa) primary;
ALTER table z
Add constraint z_fk1 foreign key (id_aa)
references a (aa);
ALTER table z
Add constraint z_fk2 foreign key (id_bb)
references b (aa);
So, I want to choose the names of the tables in such an order so as
deleting records will succeed...
I built the following sql query (using the recursive subquery factoring):
[p]
with q (r_constraint_name, table_name, constraint_name, lvl) as
(select table_name, constraint_name, r_constraint_name 1 lvl
from user_constraints one
where a.constraint_type = 'P '.
Union of all the
Select b.table_name b.constraint_name, b.r_constraint_name, q.lvl + 1 lvl
from user_constraints b
Join q
on (q.constraint_name = b.r_constraint_name)
where b.constraint_type = 'R '.
)
Select f.table_name, f.constraint_name, f.r_constraint_name, f.lvl
q f
[/ p]
I want the results as the following list:
Table-name
----------------
B2
A2
Z
A
B
C
The table - B2, A2, Z - (in any order) must first referred in the list
because they are based on the other three tables - A, B, C. Thus, in order to remove the
A, B, C table records the B2, A2, table Z records must be beleted first.
The query I posted above has the problem that it displays tables A2, B2 twice
(1 because they have a pk and 2 because they have fk referring A, B relatively tables).
Is there a solution for this problem?
Note: I use db11g v2
I wrote not all relationships of tables user_constraints (only argument constraint_name = r_constraint_name)
Thank you

Yes - the 'solution' is to use ON DELETE CASCADE, as appropriate or write a procedure that removes tables in the proper order.
The solution is NOT to try to use dynamic sql statements to do so.
You already know the good parent/child relationships. Simply create a procedure that uses the correct order.
Analyses are necessary in any case to determine the proper order AND press the appropriate values to use to remove the appropriate lines
Your DDL for tables and constraints must be in a version control system
Update the procedure when / if new constraints or tables are added to the application
IMHO, you must use dynamic SQL NOT to try to adjust automatically if a new constraint appears. New constraints should not appear by accident - they appear ONLY as part of a well planned release.

Retention of records based on the end of the calendar year
Content using WebCenter 11 g and Records Management, I'm looking for a way to create a rule of provision based on the end of a calendar year. For example, the rule might wait two years after the end of the calendar year in which the content item has been published. Does anyone know how to do this? I'm looking for something that is easy to maintain, but right now my best option is to create a metadata field to end of calendar year and then do a little iDoc script to set point which is archived for each content. I would really like to avoid this if possible. Any ideas?
I think what you're trying to do is to "synchronize on the period start date. It is part of the definition of the trigger.
http://docs.oracle.com/cd/E21764_01/doc.1111/e10640/e01_interface.htm#RMDSG620.
Assuming that the trigger is based on the release date:
-An item is activated in June 30, 2016.
-After the date of recording, wait two years. This makes the eligible trigger on June 30, 2018.
- But you want to wait until the end of 2018 to make available.
-Check the above mentioned framework would force alienation to fire on January 1, 2019, instead of June 30, 2018.

Need to set the attribute of the current record based on the value of the next record
With the help of forms 6, I have a form that displays the list of folders. There may be multiple records with the same ID, but with different expiration dates. I need set attributes for hilite only the record with the latest expiration date. The current list points of interest reviews of future expiration dates - but we found that, sometimes, the subscription is renewed before the expiration date has been reached, causing two records with the same ID with expiry dates in the future.
I can (and do) sort the records by date of expiry and the identification for the record with the latest expiration date is always the last to this ID, so what I want to do is to check the next record to see whether or not it has a different ID. If the current record is the last expiration date, & must be hilited. Because I might want to hilite the current record, I can't simply navigate to another record, according to the description I found, what makes the next_record builtin. Anyone know how I can check for a value in the next record without making the current record?
Thank you.What I would do:
-Create a DB view based on your table and including the function call DRIVE as a separate column.
-Base that block you on this point of view

I have a timestamp in a picture and I build metrics on this basis.
If the time stamp is equal to or after 18:00 every day, so, I need to create a column B with a value of 1 and if this isn't a 0
Ex:
Thanks in advance...Column A 12/12/2011 05:34:45 AM 12/1/2011 06:32:45 PM My output would look like: Column A Column B 12/12/2011 05:34:45 AM 0 12/1/2011 06:32:45 PM 1user517674 wrote:
The solution works for all, except if the timestamp is left saying 17:32 in this case.
Use:
SELECT a , CASE WHEN TO_CHAR (a, 'HH24MISS') < '173200' THEN 0 ELSE 1 END AS b FROM table_x ;SY.

Filter records based on the selection in adf 11.6
Hello
I have page, on the top section af:table displayed and tabs (af:showdetaiItem), in the section displayed below each tab having slumped workflow as a region (each workflow with the table)
After selecting any line on table top, then should filter the corresponding records on table region taskflow I am able to get the selected value to the region through input parameters task flow.
I have question concern, how to run the workflow after the selection of each row in the table? (see communication of the region)
Please suggest good approach, as appropriate
Thank you
you are correct. by passage of parameter is an approach. Another approach is contextual event...

Select a record based on the date field MAX
I have the following query that works, but does include all the necessary columns. I need to JOIN the run_events table, which is a child of the runroute table, such that I choose not only the run_code and max event_timestamp, but also the LATITUDE, LONGITUDE columns. Each run_code has many events associated with it.
Any help or pointers would be appreciated!
Thank you

Hello
One way is to use the MAX function analytical rather than the MAX aggregate, like this:
WITH
ETV as (select run_code
LATITUDE, LONGITUDE
, event_timestamp-* ADDED *.
, max (event_timestamp) OVER (PARTITION BY run_code)-* CHANGED *.
as TS
of run_events
-Group by run_code-* REMOVED *.
)
SELECT all THE RR.run_code,
substr(PODDept.POD_NAME,1,10) DEPT,
To_char (ETD ' HH: mi: SS AM') r_ETD,.
To_char (ATD, ' HH: mi: SS AM') r_ATD,.
substr (PODDest.POD_NAME, 1, 10) Dest,
To_char (ETA, "HH: mi: SS AM'") r_ETA,.
To_char (ATA, ' HH: mi: SS AM') r_ATA - if ATA is NULL, what's the point?
ETV. LATITUDE, ETV. LONGITUDE
to_char (VTE. TS, ' dd-mm-yyyy hh: mi: SS AM') TS
OF routerun RR
PADE LEFT JOIN PODDest ON RR. PODEST_CODE = PODDest.POD_ID
LEFT JOIN PADE PODDept ON RR. PODEPT_CODE = PODDept.pod_id
ETV LEFT JOIN ON RR.run_code = VTE.run_code
AND VTE.event_timestamp = VTE.ts-* ADDED *.
WHERE ATA IS NULL
ORDER BY RR. ETA, RR. RUN_CODE
/
If you would care to post, CREATE TABLE and INSERT statements for some sample data and the results you want from this data, then I could test it.
What happens if there is a tie for the final event_timestamp (i.e. 2 or more lines with the same exct run_code and event_timestamp)? You can use the analytic ROW_NUMBER function instead of MAX.
