are some special characters are got inserted in the column.
how do i find out the rows in the column which has special characters, Please help ASAP...
Thanks

Hi,
What do you mean by "special characters"?
SQL> With T As(Select 'A?BC' txt from dual union all
2            Select 'AB%C' txt from dual union all
3            Select 'ACAA' txt from dual)
4 Select txt from t where Regexp_Like(txt,'[[:punct:]]');
TXT
A?BC
AB%C
[:punct:]      Punctuation symbols
                % . , " ' ? ! : # $ & ( ) * ;
                + - / < > = @ [ ] \ ^ _ { } | ~

Finding special characters in a columns using SQL

Hi,
I have a column (Object_Name) which accepts character values. I want to find out such kind of records which has special charaters in my columns Object_Name. Please let me know, how do I write SQL statement for the same.
Thanks for your time in advance.

To find, for example, a comma in the OBJECT_NAME column try:
SELECT OBJECT_NAME
FROM MYTABLE
WHERE INSTR(OBJECT_NAME,',')>0;To find multiple special characters, for example @ # + - _ , . : ; at same time try:
SELECT OBJECT_NAME
FROM MYTABLE
WHERE INSTR(TRANSLATE(OBJECT_NAME,'@#+-_,.:;','@@@@@@@@@'),'@')>0;add a @ to the string '@@@@@@@@@' each time you add a character to the string '@#+-_,.:;'

Dynamic SQL Query to Find Special Characters in Table columns

Hi,
I am new to OTN FORUMS.
I am trying to find the columnsi of a table which have special characters in them.
I am planning on using this query
select ' select INSTR('||column_name||', chr(0))
from '||table_name||'where INSTR('||column_name||', chr(0)) >0' from user_tab_columns
where table_name='Account'
and spool the output to run as a script.
Is this the right way or do u suggest any modifications to the query?
Thanks in advance.

Hi,
I think your basic approach is right. Since you can't hard-code the table- or column names into the query, you'll need dynamic SQL.
Instead SQL-from-SQL (that is, writing a pure SQL query, whose output is SQL code), you could do the whole job in PL/SQL, but I don't see any huge advantage either way.
When you say "Special character<b>s</b>", do you really mean "one given special character" (in this case, CHR(0))?
Will you ever want to search for multiple special characters at once?
What if table foo has a column bar, and in 1000 rows of foo, bar contains CHR (0). Do you want 1000 rows of output, each showing the exact position of the first CHR(0)? If the purpose is to look at theese rows later, shouldn't you include the primary key in the output? What if CHR(0) occurs 2 or more times in the same string?
If you'd rather have one row of output, that simply says that the column foo.bar sometimes contains a CHR(0), then you could do something like this:
SELECT     'foo',     'bar'
FROM     dual
WHERE     EXISTS (
            SELECT NULL
            FROM       foo
            WHERE       INSTR ( bar
                        , CHR (0)
                    ) > 0
            );

Finding special characters in a string

Hi all, I'm using Oracle 10g.
I have a column name with special characters. how can i replace the special characters in the column with space and no space depending on the special character. please see the example below. can i use REGEXP_REPLACE?
create table
create table sample_test (
Name    VARCHAR2(20 BYTE))insert table
insert into sample_test values ('O''NEIL')
     insert into sample_test values ('B.E.VICTOR')
      insert into sample_test values ('WILLIAM,L')
       insert into sample_test values ('MARY-ANNE')
           insert into sample_test values ('VON_ANCKEN')
            insert into sample_test values ('BROWN;L')i would like the output as follows
Special Character         Name         Expected Name                  Remarks
Single Quotes            O'NEIL                  ONEIL                          Remove quotes and no space
Dot                      B.E.VICTOR         B E VICTOR                          Replace with space
Comma                      WILLIAM,L         WILLIAM L                          Replace with space
Hyphen                      MARY-ANNE         MARY ANNE                          Replace with space
Underscore                VON_ANCKEN         VON ANCKEN                          Replace with space
Semi Colon              BROWN;L          BROWN L                          Replace with space      Please advise.
Thanks
Bob

A simple solution without regexp usage:
-- Test Data
with sample_test as
select 'O''NEIL' name from dual union all
select 'B.E.VICTOR' name from dual union all
select'WILLIAM,L' name from dual union all
select'MARY-ANNE' name from dual union all
select'VON_ANCKEN' name from dual union all
select'BROWN;L' name from dual
-- Query:
select name old_name,
       translate(replace(name,'''',''),'.,-_;','     ') new_name
from sample_test;Explanation:
REPLACE deletes the quote
TRANSLATE replaces dot, comma, hyphen, semicolon and underscore

I have a MacBook purchased in 2009 with Snow Leopard. I tried to access "special characters" from the Finder menu and an intermittent blank pop ups and will not stop. It also happens when I run Word or Pages.

The blank pop up began as I tried to access "special characters" from the finder menu. I restarted, turned off and restarted and it did not work. It interferes with any application because I cannot work fast. Every new step takes a few seconds longer such as saving, finding text, check spelling and many more. I am desperate to solve this. Thanks in advance for any help given.

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

How can I find special characters in a string

Hi,
I have a small task where I have to find special characters in a given string, Can anyone suggest.......................

What is your definition of a "special character", could you be a bit more specific?
Do you simply want to find the position of a specific character in the string?
Can it occur more than once and you want to find all occurences?
What should happen if the special character does not exist?
For programming purposes, all 256 possible 8 bit characters (x00-xFF) can be treated the same. Non-printing characters can be entered in \-codes or hex display if needed.

Issue while generating MD5 if there are any special characters in the CLOB

Hi Guys,
I need your help...
We are using dbms_crypto.hash to generate the MD5 hash value for a CLOB that will be sent to other feeder systems. The feeder systems validate the file by generating the MD5 hash value on their end and compare with the MD5 generated in Oracle and accept the file only if the MD5 hash value matches.
The MD5 file matches between both the systems except in the case where there are special characters in the CLOB. Somehow, MD5 is prefixing Â character before any special character and calculating the MD5 value. In our case, our special characters being ®, §, ™, ©....
This is a high priority issue for us and it is holding our UAT.
We are using Oracle 11.2.0.2.0.
Your response is really appreciated.
Best Regards
Gupta

See if my reply in this thread addresses your problem.
Re: MD5 HASH computed from DBMS_CRYPTO does not match .NET MD5
The fix in almost all of these cases is to understand that the Crypto package always converts everything to AL32UTF8 before hashing.
ALWAYS.
ALWAYS.
ALWAYS.
Unless the 'other' hash generators (substitute any generator you wish) do it the Oracle way you will NEVER get a match.
NEVER.
NEVER.
NEVER.
There are no workarounds.

Reg Special Characters in The Names causing the problems EX: Bu00E1rbara u00E1u00EDu00F1u00E9

Hi Friends,
In the Infotype 0002 I am able to observe the Special characters in the First Name & Last Name.
When I run standard SAP report i.e. Birthday list and trying to save the output to the *clipboard option and paste it to the notepad*, I observed that last some characters were missed out depends on the special characters available in the First Name Last Name.
Assume if there are 5 special characters avialble in the Names, then 5 characters will be missed out in the output.
Please help on this issue.

OK....!!!!!
just download the Excel file (*.xls) and try open with Word-MS. In the document search by the string that you have mentioned in the question. (Use Ctrl +F).
If you see something like "ABC bla bla ba & instead of &amp , then you have to pass the data through the code I've mentioned.
You can get more details on encoding special characters UTF-8 in Google.com or Sun Websites etc.
You can also encode the & in hexadecimal format to get the desired output.

Special characters in the shared key when importing firewalls

Hello
We are using CWVMS to import and configure PIX firewalls.
The shared isakmp key of one of the firewalls has not been accepted during import because it contains special characters.
The problem is that the customer does not have authority to change the key.
Does Management Center for Firewalls really accept only alphanumeric isakmp keys ? Is there another alternative to changing the key ?
Thank you sincerely for your help.

I am not sure what your problem is. But ISAKMP keys can be changed directly on the PIX using the command line interface. I have not used any special character in the ISAKMP keys. Can anyone confirm that special characters can be used within ISAKMP keys?

Entering special characters at the command line.

I'm writing a simple program in java that automates certain processes in learning a foreign language.
This includes holding a database of vocabulary within the context of a sentence and testing a student on words they have encountered.
Nothing too tricky, except that I am having trouble with entering special characters at the command line. I'm not really surprised by this and was hoping that someone could help me.
I'm using a mixture of Solaris 8 and Mac OS X 10.3 for running the software, so anyone with any input on either of these systems will be able to help.
The characters I am trying to enter are the following:
�,�,�,�,�,�,�,�,�,�,�,�.
They are latin, and used in Spanish amongst other languages.
I'm a little confused by the implementation of character sets. I can enter these characters in applications such as word or textedit or an email, but just not at an X window.
From looking at the web it appears that these characters can be input using the
Latin1 (ISO 8859-1) character set or the ISO 10646-1/Unicode extension.
I'm just not sure what I actually have to do to get it to work.
If anyone can offer any help I'd be really grateful.
Ian Stanton

It's a problem that could be encountered in different circumstances, in this circumstance it is with a program I am writing in java.
I anticipate that these days not that many applications are delivered that require use of the command line, but since I am still learning Java it is necessary to explore this avenue.
It's interesting actually since presumably developers writing code for the international market need to accomodate characters similar to those I am attempting to enter, and more that are less familiar to me such as far and middle eastern scripts, and of course many others.
We (possibly) assume that since a character is printed on our keyboard it is a simple matter to read it in. But what if I was a Spanish student wanting to type a character into the command line and that character wasn't there? I believe that Spanish (and variants of that language) is the third most spoken language on the planet.
These characters are often relatively easy to enter in office and internet applications amongst others but apparetly not so at the command line.
Maybe this question is more suitably asked of the Unix community but I thought it a good idea to try Java since i was writing Java code and that many Java programmers could have encountered the same problem.

How set maximum of characters for the columns

Hello I use a JTable and I want to set maximum of characters for the columns.
For example column 1 max 10 characters, column 2 max 20 characters, etc..
How can I do this?

The principle is as follows: a table uses certain input components for editing a cell value, e.g. a JCheckBox for Boolean-type values or a JTextField for textual/numerical values. By default, a JTextField doesn't have any size limit, so you can enter as many chars as you want. In order to change this behaviour, you'll have to
1.) create a JTextField that does have a size limit and
2.) set a CellEditor on the JTable which uses this manipulated JTextField.
An easy way for 1.) is to create a custom Document (the internal data representation for text components, the M-part of the MVC -- see javax.swing.text.Document) that doesn't accept any text beyond a given limit, e.g.:
public class LimitedDocument extends PlainDocument {
private int max = 0;
public LimitedDocument(int max) {
    this.max = max;
public void insertString(int offset, String str, AttributeSet a) throws BadLocationException {
    // too long for the limit; get current contents, insert, and cut off trailing chars
    if ((getLength() + str.length()) > max) {
      StringBuffer buf = new StringBuffer(getText(0,getLength()));
      buf.insert(offset,str);
      remove(0,len); // remove current text contents
      super.insert(0,buf.toString().substring(0,max),a); // insert whole text
    // no problem, will fit
    else {
      super.insertString(offset,str,a);
}Then, in order to set the cell editor -- for example for the first column --, you can do as follows:
myTable.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(new JTextField(new LimitedDocument(5),"",5)));This will create a new DefaultCellEditor (see javax.swing.table) and initialize it with a given text field which will be responsible for any edition in this column. As the text field itself is created using a limit of 5, it should accept no text insertion beyond 5 chars.
