Function to extract only numeric value

Hi
I have a column which contains alphanumeric number like LAX4308720
Is there any function in oracle so that I could extract only the numeric values like
4308720 from that string..?
Please provide me some solutions
Shelly

You can use translate as demonstrated above.
You just have to make sure you translate out all the characters that you don't want that may appear in the string. e.g. if the only other characters are uppercase A-Z then you can just use:
SQL> ed
Wrote file afiedt.buf
1* select replace(translate('LAX4308720', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789','??????????????????????????0123456789'),'?') from dual
SQL> /
REPLACE
4308720

Hi all.
Can some one please tell me Is there any Function Module to validate only numeric values?
Like in year variable, it can never contain alphanumeric values or special symbols?
Is there any function module to check, wheather the variable contains only numeric values, no alphanumeric value or special symbol?
If there is no as such function module then what is the alternative approach we can take?
Plz help me .

How to restrict the user to enter only numeric values in a input field

How to restrict the user to enter only numeric values in a input field.
For example,
i have an input field in that i would like to enter
only numeric values. no special characters,alphabets .
reply ASAP

Hi Venuthurupalli,
As valery has said once you select the value to be of type integer,once you perform an action it will be validated and error message that non numeric characters are there will be shown. If you want to set additional constraints like max value, min value etc you can use simple types for it.
On the project structure on left hand side under local dictionary ->datatypes->simple types create a simple type of type integer
The attribute which you are binding to value property ;make its type as simple type which you made
Hope this helps you

Extracting only Scale value ..how to do this

Hi,
How to fetch only scale value from a number value..?
example from 1000.1212 i have to select 1212 only..
I want any oracle supplied function to do this..
i tried substr and instr but i want can we do this a function available in oracle
Thanks

No you have to use the existing sql functions:
SQL> select to_char(sysdate,'YYYY') from dual;
TO_C
2006
SQL> select to_char(to_date('2003-08-22','YYYY-MM-DD'),'YYYY') from dual;
TO_C
2003
which you can include in your own function:
create or replace function extract (p_1 in varchar2,p2 in varchar2) return integer is
begin
declare v_return varchar2(30);
begin
    if p_1 = 'YEAR FROM DATE' then
      select to_char(to_date(p2,'YYYY-MM-DD'),'YYYY')
      into v_return
      from dual;
    end if;
    return to_number(v_return);
end;
end;
/SQL> select extract('YEAR FROM DATE','2003-08-22') from dual;
EXTRACT('YEARFROMDATE','2003-08-22')
2003

SUBSTR function to extract an specific value

I have data like this in a columnn
RA&(44)RC&(44)RF&(44)RJ&(44)RN&(44)RU
RI&(44)RQ&(44)RR&(44)RS
RQ&(44)RR&(44)RS
RG&(44)RP
I want to be able to ectract just the values RA,RC,RF ETC..ETC...
I try substr does not work:
SELECT SUBSTR(szcasup_activities,1,2),
      SUBSTR(szcasup_activities,8,9) ,
      SUBSTR(szcasup_activities,15,16)
      FROM szcasup
{code}
I also try
{code}
SELECT
     REGEXP_REPLACE (szcasup_activities,
                                         '&(44)',
                                         NULL)
                                         FROM szcasup
{code}
to eliminate &(44) does not work
Any ideas?

Not sure how you'd expect your final output, so maybe
SQL> with t as (
select 'RA&(44)RC&(44)RF&(44)RJ&(44)RN&(44)RU' szcasup_activities from dual union all
select 'RI&(44)RQ&(44)RR&(44)RS' from dual union all

Validation on numerical values in webdynpro

Hi Friends,
I am facing one probelem with validation on numerical values. In my application there is a scenario.. Input fields are Mibile number and email id.
when i enter the invalid phone number like : 09988wertyy    it should throw the error like enter only numerical values.
In the same way i should validate the email id with format .. like ratnakar.alwala@ accenture.com. if it is in valid then it should throw the error.
could any body please give me the approach.
Thanks and Regards
Ratnakar reddy alwala

Hi Ratnakar,
For number validation, what I did was :
1. Bind a context variable (Say Number) of type String to the input Field
2. At the time of submission, do the following
String num=wdContext.xurrentContextElement().getNumber();
if(num!=null)
try
        double num=new Double(amnt.trim()).doubleValue();
catch(NumberFormatException exc)//IF AMOUNT ENTERED IS NOT VALID
   wdComponentAPI.getMessageManager().reportException("Invalid Number",true);

Limiting entry in a JTextField to numeric value and "%" value

Hi,
I want to allow the user to enter numeric value and % value
How can I limit the user to make such a entry in JTextField

Use the code given below to make your textfield accept only numeric values. You can modify itto include % values too.
textField.setDocument( new TextFieldVerifier() );
class TextFieldVerifier extends PlainDocument {
public void insertString( int offset, String str, AttributeSet attSet ) throws BadLocationException {
boolean valid = false;
if ( str == null ) {
return;
String old = getText( 0, getLength() );
/* insert the new string at the given offset, into the old string */
String newStr = old.substring( 0, offset ) + str + old.substring( offset );
try {
/* check if the new string is a valid integer */
Integer.parseInt( newStr );
valid = true;
} catch ( NumberFormatException ne ) {
/* invalid, if not an integer */
valid = false;
Toolkit.getDefaultToolkit().beep();
if ( valid ) {
super.insertString( offset, str, attSet );
}

Need to extract non empty value thru MDX

Hi All,
I have a requirement where there are 2 measures A and B.. I need to populate the first non-missing value from a layer from A in to B..
tried using HEAD function however looks like in ASO MDX member formulas does not support this ..
Any help would be highly appreciated
Thnks,

I believe the issue is that the formula you are using returns a set and you are looking for a value. Therefore, you need to use the Head function with a function that returns a numeric value (ie: Sum, Max, Avg, etc). In instances like this I typically use the Sum function. Depending on your cube and the rest of your formula, you may need to put some additional work into the formula so that the Sum returns just the value you need, but it just requires getting more specific in your arugments.
The Head formula will bring back the first member or tuples specified, but won't evaluate for non-missing. You may need to also combine the Head forumla with the Filter formula. ex: Sum(Head(Filter([Dimension or Member].SetFunction,[A] <> Missing)),1) You will mostly need to select some other dimension to apply the filter to (like period or scenario). Examples of the SetFunction are Children, Members, Levels(0), etc. If you end up going this route you may want to write out your Sum(Head()) function and and Sum(Filter()) function and validate each independently and then merge. I find this helps when trying to build larger nested functions.
Hope this helps!

Version 2(PL/SQL) above is not clear enough, It can be tuned to the following:
-- Create a function
Create or replace function IsVARCHAR(pCol VARCHAR2) return VARCHAR2
AS
vNumber NUMBER := 0;
begin
vNumber := to_number(pCol);
RETURN NULL;
Exception
When Others Then
RETURN pCol;
End;
-- To See VARCHAR values (alpha-numeric) only!
SELECT col1 FROM tab1
WHERE IsVARCHAR(col1) IS NOT NULL;
-- To See NUMBER values only!
SELECT col1 FROM tab1
WHERE IsVARCHAR(col1) IS NULL;Versatility here with PL/SQL, but I personally like SQL versions.

Function to check whether a value is NUMERIC

Hi
I have a requirment, where I need to check for a field whether it contains a valid numeric value or not.
Could you please suggest a function.
If I use TO_NUMBER(VAL1) it throws an exception in case of an non_numeric value.
The requirement is as follows.
If the field 'val1' contains a numeric value then the function should return the coressponding nueric value. If it is not,then return a boolean value are a return code instead of exception.
Is there are built in function in ORACLE to acheive the same , please advice.

Hi,
The best way to do it is using User Defined Function, i have written a function as per your Requirement...It is give the data if it is numeric else it will return FALSE
create table Testdata
as
select '10' n from dual
union all
select 'xx' from dual
union all
select '20' from dual
union all
select '3YY' from dual;
CREATE OR REPLACE FUNCTION IsNumeric
(p_col_value IN VARCHAR2)
RETURN     VARCHAR2
AS
v_val NUMBER;
BEGIN
v_val := TO_NUMBER (p_col_value);
RETURN 'TRUE';
EXCEPTION
WHEN VALUE_ERROR THEN
          RETURN 'FALSE';
     WHEN OTHERS THEN
          RETURN 'FALSE';
END IsNumeric;
Select Decode(IsNumeric(n),'TRUE',n,'FALSE') from Testdata

How to 'Only' allow Numeric value in the Edit Box in AcroDialogs

Hi all,
I've create an AcroDialog wizard, I need to allow onlu numeric values in the Edit Box. Can someone please help me with this validation?
Regards,
Chris

There isn't a keystroke event for custom JavaScript dialogs, or any proper interactive events for the fields. You can validate fields when the user presses OK, and you can test fields when the user changes focus by setting the "Action" property for the field. But the only practical way to restrict user input to numbers is to use George's suggestion. There is a number property for the fields but it has an undesirable side affect and I never use it.

How do I copy/paste full numerical-only account strings into the Projects WebADI template when the account segment fields in the template require use of the dropdown because they're formatted as alpha-numeric values?

How do I copy/paste full numerical-only account strings into the Projects WebADI template when the account segment fields in the template require use of the dropdown because they're formatted as alpha-numeric values? I'm using the Integrator named "Projects - Transaction Import" and a custom Layout created based on the seeded Layout named "Transaction Import - Accounted". Do I need to somehow change my Layout to make the Document accept numerical values instead of requiring alpha-numeric values? I need to be able to populate the Document with a large amount of transactions and cannot feasibly go through every transaction to add the alpha-valued name of the account segment to every segment that requires it. The segments in particular causing the problem are "Expnd Type" and "Organization Name" which are both alpha-numeric and as such contain the segment number and name; I need to be able to only have to enter the Natural Account Number (6-digit number only) and the Organization Number (5-digit number only).
