Removing non-alphanumeric characters

Hello,
New to Oracle (not so new to SQL) and this is my first post ... please be kind :-)
Anyway, I have a variable length string that I would like to separate into separate rows/columns. the structure is as follows:
|G^7130^R|C^7130^R|G^7131^R|C^7131^R|G^9900^R|C^9950^R|C^9951^R
... the leading alpha following the pipe is required in a column as is the numeric that follow. I have tried ...
REGEXP_REPLACE(string, '[^[:digit:]]',',') which gave me ...
,,,7130,,,,,7130,,,,,7131,,,,,7131,,,,,9900,,,,,9950,,,,,9951,,
..wrong...
I am trying to produce ..
code value
G 7130
C 7130
etc
Anyway any help would be appreciated .... and yes I am going through the literature as fast as I can ... well at least as fast as I can comprehend.
Thanks.

I am seeking some assistance on the implemenation of the above solution. I have modified the query (below) and am unsure of why the performance is so poor (no crticism to the contributers). When I run the Explain Plan against the SQL the total cost is very low (<50) ... yet when I run the query it does not return within hours (I cancel the process). Does anyone have any advice on this one? I have to be missing something here. Any help would be appreciated. Thanks.
Regards,
Al

Removing Non-numeric characters from Alpha-numeric string

Hi,
I have one column in which i have Alpha-numeric data like
COLUMN X
+91 (876) 098 6789
1-567-987-7655
so on.
I want to remove Non-numeric characters from above (space,'(',')',+,........)
i want to write something generic (suppose some function to which i pass the column)
thanks in advance,
Mandip

This variation uses the like operators pattern recognition to remove non alphanumeric characters. It also
keeps decimals.
Code Snippet
CREATE FUNCTION dbo.RemoveChars(@Str varchar(1000))
RETURNS VARCHAR(1000)
BEGIN
declare @NewStr varchar(1000),
@i int
set @i = 1
set @NewStr = ''
while @i <= len(@str)
begin
--grab digits or (| in regex) decimal
if substring(@str,@i,1) like '%[0-9|.]%'
begin
set @NewStr = @NewStr + substring(@str,@i,1)
end
else
begin
set @NewStr = @NewStr
end
set @i = @i + 1
end
RETURN Rtrim(Ltrim(@NewStr))
END
GO
Code to validate:
Code Snippet
declare @t table(
TestStr varchar(100)
insert into @t values ('+91 (8.76) \098 6789');
insert into @t values ('1-567-987-7655');
select dbo.RemoveChars(TestStr)

Non-alphanumeric characters in textarea causing 404 errors

I'm only just becoming acquainted with Coldfusion, as I've been asked to fix a problem in an existing system. The system consists of a simple html form containing a text area, among other input fields. The form is submitted to a cfm script, which displays a confirmation page and sends a couple of emails. The problem is that whenever the user enters any (as far as I can tell) non-alphanumeric characters, e.g. quotes, commas or brackets, in the textarea field, they get a 404 response from the server.
I tried a number of things to identify the problem, including escaping the text in javascript before submission, but didn't get anywhere. The last thing I tried was installing a local version of the CF on my workstation, hoping to reproduce the problem and thus debug it more easily. However, on my local CF setup the problem does not occur.
Can anyone help me debug this please? Thanks,
Marcin

Thanks for your response. The form method is "post". The only thing that the CFM handler does with this field (gametestexperience) is include it at the bottom of an email message:

[solved] Non-alphanumeric characters broken in TinyChat

Hello, fellow archers.
I've been having a bit of trouble with the TinyChat site. Most non-alphanumeric characters are being displayed as crossed-out boxes. This problem is exclusive to TinyChat and has not occured in any other Flash applications.
An example of the broken characters:
Note how the / and > characters are not broken.
This is the second installation of ArchLinux on my computer, the problem occured on the current install only. I suspect the problem is caused by a missing package, though the only hint I was able to find was installing the ttf-ms-fonts package (https://wiki.archlinux.org/index.php/br … ash_Player). This did not resolve the issue.
Package versions:
firefox 34.0.5-1
flashplugin 11.2.202.425-1
I'll gladly provide any other information that could help resolve this issue.

Whops. The subject length was exactly at the maximum length, and since I couldn't edit the title any further, I thought a moderator had to edit it. Apologies!

How to discard non alphanumeric key in a string ?

Dear all,
To start an application that i have developped, i would like that the user write its password in the first panel but i want that each time that user enter a character in the string control Hide_Password (see attached picture), this one is automatically convert in a "." to hide the password . The real password is saved in a second string control. It is actually what my vi is doing by using a Key Up event. But now i want to prevent any non alphanumerical character to be enter in the password, especially i do not want that the user can press the menu key as <Ctrl>, <Shift>, <Alt>, <Command>, and <Option> and also the <Left>, <Up>, <Right>, <Down>. I suppose that i have to use Key Down? event by discarding all the key that i do not want but i am sure that there is a more easy way to do it.
Do you have any idea ?
Morover, If you think that there is something wrong in my vi, please let me know.
Thanks
Philippe

The real password is saved in a second string control.
One thing you shouldn't do is use a (hidden?) String control for data storage. Use the one control for data input (as a password as others have suggested) and pass the data throughout your program with a wire.

Non-Alphanumeric Character in a String

I understand if we have a non-alphanumeric character in a String, we have to put a backward slash in front of that character. For example, we have to put a backward slach in front of a "backward slash". Eg. we do \\ to put a backward slash in a String.
What about a dot (.) or a dash (-)? Do we have to do the same thing?

No, it's only for control characters like "newline", characters with special meaning in strings i.e. " and \ and any character that can't be represented in the character encoding of your java source file.

How to support non alphanumeric characters when using WORLD_LEXER?

BASIC_LEXER has an attribute of printjoins which we can specify the non alphanumberic characters as normal alphanumberic in query and included with the token. However, WORLD_LEXER doesn't have this attribute. So in order to use some non alphanumberic characters and treat them as alphanumberic characters in Oracle Text Index, such as ><$, what should I can?
Thanks in advance for any help.

I use WORLD_LEXER to create Oracle Text Index to support UTF-8.
Below is the script to create table and index:
REM Create table
CREATE TABLE my_test
( id VARCHAR2(32 BYTE) NOT NULL,
code VARCHAR2(100 BYTE) NOT NULL,
CONSTRAINT "my_test_pk" PRIMARY KEY ("id"));
REM create index
exec ctx_ddl.create_preference('stars_lexer','WORLD_LEXER');
exec ctx_ddl.create_preference('stars_wordlist', 'BASIC_WORDLIST');
exec ctx_ddl.set_attribute('stars_wordlist','substring_index','TRUE');
exec ctx_ddl.set_attribute('stars_wordlist','PREFIX_INDEX','TRUE');
-- create index for Table corrosion level
CREATE INDEX my_test_index
ON my_test(code)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('LEXER stars_lexer STOPLIST stars_stop WORDLIST stars_wordlist SYNC(EVERY "SYSDATE+5/1440") TRANSACTIONAL');
INSERT INTO my_test('1', 'English word1');
INSERT INTO my_test('2', '违违');
INSERT INTO my_test('3', '违违&^|违违');
When I query:
select * from corrosion_levels r where contains(r.CORROSION_LEVEL, '{%违${|违%}') > 0
ID CODE
3 违违$(|违违
2 违违
Actually, the result what I want is: 3 违违$(|违违
So the requirement is that all non-alphanumeric characters should be treated as normal alphanumeric charcters. Please tell me how to implement it.

BUG: registered servers missing when password contains non-alphanumeric

I have a fresh installation of DS7 using Sun Java Web Server 7 to host DSCC7. Using DSCC7 web interface I click New Server and the procedure appears to complete successfully (no errors during creation, registration successful). However in the web interface the new server is not listed.
From the command line the new server is listed.
$ /opt/SUNWdsee7/bin/dsccreg list-servers
Hostname Port sPort Type Owner Flags iPath Description
www-c-directory 389 636 DS nobody /var/opt/SUNWdsee7/internal
Cause: the DSCC administrator's password contained non-alphanumeric characters (e.g. a left-angle bracket plus a few other punctuation characters) with about 10 characters in total.
Solution: from the web interface I navigated to Settings, Directory Service Managers, and changed the password for "admin" to a simpler password containing only alphanumeric characters.
Resolution: the registered servers now appear in the DSCC7 web interface as well as the command line. Oddly I can now return the password back to its original value and the servers still appear in the web interface.

Removing non-numeric characters from string

Hi there,
I need to have the ability to remove non-numeric characters from a string and I do not know how to do this.
Does any one know a way?
Example:
Present String: (02)-2345-4607
Required String: 0223454607
Thanks in advance

Dear NickM
Try this this will work...........
create or replace function char2num(mstring in varchar2) return integer
is
-- Function to remove Special characters and alphebets from phone no. string field
-- Author - Valid Bharde.(India-Mumbai)
-- Date :- 20 Sept 2006.
-- This Function will return numeric representation.
-- The Folowing program is gifted to NickM with respect to his post on oracle site regarding Removing non-numeric characters from string on the said date
mstatus number :=0;
mnum number:=0;
mrefstring varchar2(50);
begin
mnum := length(mstring);
for x in 1..mnum loop
if (ASCII(substr(upper(mstring),x,1)) >= 48 and ASCII(substr(upper(mstring),x,1)) <= 57) then
mrefstring := mrefstring || substr(mstring,x,1);
end if;
end loop;
return mrefstring;
end;
copy the above program and use it at function for example
SQL> select char2num('(022)-453452781') from dual;
CHAR2NUM('(022)-453452781')
22453452781

Removing non printable characters from an excel file using powershell

Hello,
anyone know how to remove non printable characters from an excel file using powershell?
thanks,
jose.

To add - Excel is a binary file. It cannot be managed via external methods easily. You can write a macro that can do this. Post in the Excel forum and explain what you are seeing and get the MVPs there to show you how to use the macro facility
to edit cells. Outside of cell text "unprintable" characters are a normal part of Excel.

Merge files and remove non-static elements

Where is the feature that allowed images to be merged while removing non-static elements. I saw a demonstration of removing people from a scene when multiple pictures were taken and the people had changed their positions. This was touted as a feature found only in PS extended a few years ago. I have never been able to locate it.

This involves an "Image Stack". See http://help.adobe.com/en_US/photoshop/cs/using/WS1E389632-4B37-425e-8EAB-1384C0B432D3a.htm l
