PL/SQL :: Continuous Data Range Algorithm?
May 3, 2013
I have in my database table 2 important date columns: StartDate (Not null) and EndDate(Allowed Null).I want to ensure that all records in the table would always create perfect contiues date ranges with no holes inside.Wor example there may not be records [1-may..1-may, 3-may-...] because there would be a hole [2-may...2-may]. Holes are not allowed.
And overlapping is not allowed, for example [1-may..1-may, 1-may-2may, 3-may-...] is not allowed because overlapping occures on day 1-may. Overlapping and holes are not allowed. But it is allowed that table has no records at all. But all DML manipulations with existing records must ensure that overlapping and holes won't occur.How to write such check? How to ensure that data ranges would stay continous with no holes and no overlaps?

For e.g.
if my data is as follows
EX_START_DATE EX_END_DATE EX_CHARGE
5/1/2005 5/5/2005 11:59:59 PM 10
5/6/2005 5/7/2005 11:59:59 PM 10
5/10/2005 5/15/2005 11:59:59 PM 10
5/17/2005 5/19/2005 11:59:59 PM 10
5/20/2005 5/25/2005 11:59:59 PM 20
the record
5/6/2005 5/7/2005 11:59:59 PM 10
is in continuation for
5/1/2005 5/5/2005 11:59:59 PM 10 with the same ex_charge
so i need the output as
5/1/2005 5/7/2005 11:59:59 PM 10
5/10/2005 5/15/2005 11:59:59 PM 10
5/17/2005 5/19/2005 11:59:59 PM 10
5/20/2005 5/25/2005 11:59:59 PM 20
and the remaining rows as it is
(Note :date in mm/dd/yyyy format)

We are attempting to configure/use OEM (Oracle 10.2.0.4) on Solaris, and when logging in to OEM we are directed to the Database Down page, stating Enterprise Manager is unable to connect to the database instance, but showing all the components as up/open. After checking the log, I found the following error:
IO exception: Unknown Encryption or Data Integrity algorithm
I checked the settings in emoms.properties and compared the encryption parameters to those in our SQLNet file, and all match up. We are NOT using Grid Control, just db control connecting to 1 instance.

I have dcs_sku table .The record count is 50 thousand in that table.My requirement is to fech every row,create an xml out of it and post the data to some third party.As the count is very huge,I can't select the entire record and do the operation at a time.way which I will run the sql query in a loop,which will fetch 1st from rown 1 to row 1000,next 1001 to 2000,2000 no 'n' row...
I tried the below query:
select * from dcs_sku where rownum between 1 and 200...This gave me the 1st 200 rows and worked fine.
but the moment I changed the query to :
select * from dcs_sku where rownum between 201 and 300:::No result was coming up.

i create form on which 3 window, 3 Canvas, 3 blocks are there.
1)first block contain 3 items from_date and to_date(nondatabase)and find button
2)second block contains 3 items segment1, quantity and payment_terms
when i enter 2 dates and click on find button 2nd window open. segment1 and quantity between this 2 dates comes from base table like
select segment1,quantity
from po_lines_all pll, mtl_system_items mts
where pll.ITEM_ID=mts.INVENTORY_ITEM_ID
and creation_date between :FROM_DATE and :TO_DATE
and payment_terms should enter manually
3)2nd block contains summary button when i click on it, it save segment1, quantity, payment_terms and open new window which contain segment1 ,qty, payment_terms and when i click on summary button data comes from custom table which group clause means
suppose
item qty terms
a 2 2days
a 3 2days
b 3 3days
then on third form i shows like this
a 5 2days
b 3 3days
i done all this things but problem is that
suppose once data between 21-aug-2010 and 24-aug-2010 comes on second form , i enter payment_terms and save it. sumaary form also run properly but if another user enter date between 22-aug-2010 and 30-aug-2010 then it will shows data between 21-aug-2010 to 24-aug-2010 from custom table i.e with payment terms as earlier it save and from 25-aug-2010 to 30-aug-2010 it shows data from base table
like
item qty terms date
a 2 2days 21aug
a 3 2days 22aug
b 3 3days 24aug
b 4 NULL(ENTER MANUALLY) 26aug
c 5 NULL 27aug

I would like to cretae 3 partitions for a table
partition 1 = < 2011
partition2 = <2012
partition 3 = any other value not staisfying partition 1 and partition 2
i would like to know how to create a partition 3 without specifying the range so that the data which are not coming under the range of other partitions (Partition 1 & 2) will automatically goes to this partition 3.
Also in the above case if i insert data of year 2009 then where will it go , to partition 1 (or) 2 since both of them matches the condition (<2011 and <2012) (or) do i need to use between clause while creating partitions?

I have seen in probably VB or Dot net software being used at some premises that there "formula computation is live and interactive".
What i means that suppose a cashier has made invoice having total of 83$. Mow in the text box for entering amount received, the cashier is about to enter 100 but surprisingly the returned value/remaining value (total invoice - amount received) is being computer LIVE.
This is what happens.
1) The cashier entered 1 and the remaining value instantly showed 82 (83-1)
2) then on other key stroke of 0 by cashier and then then the remaining value instantly showed 73 (83-10)
3) then on other key stroke of 0 by cashier and then then the remaining value instantly showed 17 (83-100)
Hence a continuous updation/changing of the remaining value on every key stroke is observed.

I've a holiday master in which date of holiday is present. It also contain all Sundays.
I've a process which is not executed on Sundays and Holidays. After holidays it must process all data.
E.g.
01-NOV-2011 --Holiday
02-NOV-2011 --Holiday
03-NOV-2011 --Sunday
On 31-OCT-2011 Process is executed for same day data. Since 1,2-Nov are holidays and 3-nov is Sunday. The process will be executed on 04-Nov-2011 for data between 01-Nov-2011 to 04-Nov-2011. On 05-nov-2011 process will be executed for same day data. Then the process will be executed on 07-nov for 6,7-nov data, because 6-nov was Sunday.
It's like
SELECT *
FROM TABLE_NAME
WHERE BUSINESS_DATE BETWEEN LV_START_DATE AND LV_END_DATE ;
How to select this LV_START_DATE, LV_END_DATE i.e. MIN & MAX date for a topmost continuous range less than the business date.
Sample Data.

I have table :TABLE_X and want to select some data locate into specific range of Day/Month. But so far i couldn't find out the way to.
For example, i want to select people born within specific range of date(range : sysdate to (sysdate+7months ahead) Year here should not be consider, only the day and month.
e.g. a range could be from today:Sept,20 to Apr,18.
so what i was trying is to select doing the following.
select TABLE_X_ID, TABLE_X_BIRTH_DATE
from TABLE_X
where to_date(TABLE_X_BIRTH_DATE, 'DD/MM')
between to_date (to_char(SYSDATE, 'DD/MM'), 'DD/MM')
and to_date (to_char(SYSDATE+210, 'DD/MM'), 'DD/MM')
first am not sure if BETWEEN & AND will work for this case, bt it was the most logical way i could think about to get such range.
