Is there a function to predict the next point accoding to the known point?

For example
ten points arranged in a parabola,
is there a function to predict the coordinates of the six point behind according to the four points in front of?

The ability to predict data values is predicated on your data having some sort of inherent structure. In cases where your data has that structure, curve fits can be very helpful. However, if your data does not have any inherent structure, or is too noisy to
be able to see the structure, you can run curve-fits and still get results
that look reasonable. Unfortunately those results would probably correlate better with the
phase of the moon than they would what you are measuring. No matter how fancy, mathematics can only predict a probable value based on what it was given - and as in all things computer: GIGO. Hence, when working with this sort of thing, I always bear in mind this definition of a pocket calculator:
"...a device that can divide a ball park estimate by a wild-ass guess and come up with an answer accurate to 13 decimal places..."

IS THERE A FUNCTION TO RETURN THE NUMBER OF MONTHS OR DAYS?

I know that you can do a months between function between 2 dates divided by 12 and get years but is there a function that can return the number of months between 2 dates or the number of days between 2 dates in a select statement for a report? These 2 dates are entered in an Oracle forms.
I have 2 dates.
BEG_SVC_DT 30-JUL-1995 DATE FORMAT
END_SVC_DT 981007 VARCHAR2 FORMAT Positions 5 and 6 are the days.
I must subtract BEG_SVC_DT from END_SVC_DT.
In PLSQL I add 31 to 07 and get 38. I subtract 30 from 38 and get 8.
or I have 2 dates
BEG_SVC_DT 10-JAN-2003 DATE FORMAT
END_SVC_DT 050924 VARCHAR2 FORMAT Positions 5 and 6 are the days.
I must subtract BEG_SVC_DT from END_SVC_DT.
In PLSQL I subtract 10 from 24 and get 14.
In both scenarios the end_dt field must be VARCHAR2 because the user has to enter the word 'PRESENT' . Is there a function in SQL that would compute the
number of days between 2 dates?

BEG_SVC_DT 12-JUL-2004 DATE FORMAT
END_SVC_DT 050807 VARCHAR2 FORMAT Positions 3 and 4 are months.
I must subtract BEG_SVC_DT from END_SVC_DT
JUL is the 7th month.
In PLSQL, I subtract 07 from 08 and get 01
Or I have 2 dates
BEG_SVC_DT 13-NOV-2004 DATE FORMAT
END_SVC_DT 050429 VARCHAR2 FORMAT Positions 3 and 4 are months.
I must subtract BEG_SVC_DT from END_SVC_DT.
NOV is the eleventh month. 04 is less than 11.
In PLSQL I have to add 12 to 04 and subtract 11 from 16 to get 05.
In both scenarios, the end_dt field must be VARCHAR2 because the user has to enter the word 'PRESENT'. In SQL, is there a function to compute the number of months between 2 dates?
I am doing my calculations this way because this is the way that the user has been doing them when they created the report manually.
The database that I am using is Oracle 9.2.0.6
Report Writer Report Builder 6.0.8.22.0
Forms 6.0.8.22.1

In your example:
BEG_SVC_DT 30-JUL-1995 DATE FORMAT
END_SVC_DT 981007 VARCHAR2 FORMAT Positions 5 and 6 are the days.
I must subtract BEG_SVC_DT from END_SVC_DT.
In PLSQL I add 31 to 07 and get 38. I subtract 30 from 38 and get 8.
Where is the "31" depending on, on year and month of BEG_SVC_DT or END_SVC_DT?
What would be the answer for the following example
BEG_SVC_DT 25-FEB-1995 DATE FORMAT
END_SVC_DT 980407 VARCHAR2 FORMAT
Do I add 28 (=number of days in FEB-1995),
or 30 (=number of days in APR-1998),
or 31 (= max number of days in any month?)

Is there a function to get the IP of this remote system

Hello EveryBody
Currently I have an application that runs on our network. When someone logs on to the network it checks there system and gets the pc name. I would like to also get the IP address of that system. As well I may later like to ping that computer.
1) Is there a function to get the IP of this remote system?
2) IS the a function to ping a remote system and receive back the response?
Thanks a lot.

Because if wan or internet then the remote computer would have to have an address that is reachable from your computer. For the internet this would mean it would have to be public. And for a wan the IP would have to be unique across the wan.

Is there a function to open the outlook mail and to attach certain..

Hello,
Is there a function to open the outlook mail and to attach certain selected files?

here is a code snippet from one of our programs
data: out type ole2_object,
        outmail type ole2_object,
        att type ole2_object,
        atts type ole2_object.
      create object out 'Outlook.Application'.
      call method of out 'CREATEITEM' = outmail
        exporting
          #1 = 0.
      set property of outmail 'SUBJECT' = 'Smartform Output from SAP'.
      call method of outmail 'ATTACHMENTS' = atts.
      call method of atts 'ADD'
        exporting
          #1 = p_file.
      call method of outmail 'DISPLAY'.
in our case, we save the data to a local file with the path p_file.
so, we create the attachment on a local drive, at path p_file
we open outlook
we create a mail item
we set the subject
we add the attachment
and we call disply, to pop the email up for any changes the user wants to make.
in other programs we also use
set property of outmail 'TO' = alvline-prc_email.
to set the TO address of the email
hope this helps

Is there any function to get the name of the days?

But just want to know whether there is any other way.
I need to show the 7 days in a poplist in my form, thats the requirement
Thanks

I think you should use a pl/sql function for this.
Nah ... just joking.
I'd be tempted to just use a union all statement to return the seven literals. People will look at it and know exactly what it does.Yeah, agreed, I was just demonstrating that the format mask of a to_char(..., 'Day') pads with spaces, which seems to have been missed in the above answers. ;)

Is there a way to predict the AppStore link

I want to include a send to friend function in my installed application what would include a link to itself on the AppStore. Is there a way to predict ahead of time what the AppStore link will be.

There is no easy predictor. If the source data is text, it will compress amazingly well. If it is an already compressed format, like video, you may end up with a larger file than the original.
You can always make the tarball, and then see how big it is..if it is too large to fit on a single CD, maybe consider DVDs, or use a file splitter so your tar can span more than one CD.

Is there a function to adjust the touch on the touch screen? Its been very sensitive lately

iphone has been very sensitive to my touch. Is there a setting or function to adust the touch on the touch screen?

Based upon your OP, I don't think Assistive Touch is what you want. For more info on AT, see p. 155 of the User Guide.
For your problem, try cleaning the screen and/or removing your screen protector. It's a long shot but quick and easy to do.
If still a problem, try restoring with your backup.
FYI, there is no adjustment for the touch screen sensitivity.

Is there a function to calculate the period range?

E.g. the program input the 10.2008 - 01.2009 (MM/YYYY), so how can the program knows there are 4 months: 10/08, 11/08,12/08, 01/09 between them?
Is there function can do so?
P.S. yes it can be done, if calculate it manuly via while(in ABAP) clause

Hi,
Check this code..
DATA: V_FROM(6) TYPE N VALUE '200810'.
DATA: V_TO(6) TYPE N VALUE '200901'.
DATA: V_DATE TYPE D.
* Get the periods.
DO.
CONCATENATE V_TO '01' TO V_DATE.
* Decrease one day.
V_DATE = V_DATE - 1.
WRITE: / V_DATE(6).
* Exit condition.
IF V_DATE(6) = V_FROM.
EXIT.
ENDIF.
ENDDO.

Is there a function to output the crossing point of two plotted lines

I got some data plotted on a graph, I need to find the crossing point of the plotted lines on the graph (The plotted data curves are not linear lines) and detect it by an indicator. I could compare the to data arrays plotted and output the two closest data numbers, but the really crossing pionts is sertainly an intercept of two Interpolated values made by the graph, wich are not in my data buffers. any suggestions will be full Stared

I only did a cursory look and didn't find any built-in function that jumped up screaming "I'm it! I'm it!", but that doesn't mean something doesn't exist given the large number of functions available with LabVIEW. An alternate solution is to use linear interpolation between successive points. If the points are close together then you can assume a straight line between the points and break this down to the simple case of finding the intersection of two lines, which is trivial. Not sure how computationally intensive of an algorithm this would be, and there would clearly be some error involved, and you will need to determine if the error is tolerable for you.

Is there any function that returns the latest DDL statement

can anyone tell me if there is any FUNCTION that returns latest DDL statement performed in a schema.
OR
if there is any TABLE that will be populated with latest
DDL statement in schema.
THANK YOU.

The table all_objects (and/or dba_objects) contains a column called last_ddl_time. Thus, a query like
scott@jcave > SELECT max(last_ddl_time)
2 FROM all_objects
3 WHERE owner = 'SCOTT';
MAX(LAST_DDL_TI
28-NOV-03will tell you the last time any object owned by SCOTT had DDL issued against it.

I am trying to write a backup script that will create gzipped tarballs that will fit on a CD.
Maybe I am approaching this from the wrong direction, any advice is much appreciated.
