• How to find special characters in a string of give/sentance

  Hi all
  
  I have a task to complete with the time to give. Because I'm not very good in PL/SQL, I need you're help.
  Condition is:
  
  I must come with the SQL or PL/SQL code which should return and find the hidden or special character in the name of the data files in a database. There are nearly 400 + database are present in almost any flavor of UNIX, and I need to check the database each.
  
  As you know, the name of the data file will be like this:

   /u02/instance_name\oradata\datafile_01.dbf 

  So, it should avoid these things and only discover the special characters in the name of the data file.
  

   
  a-z , A-Z , 0-9 and \ 

  Please keep in mind that... I'll be pulled the script Oracle the Oracle 9i client that will access all the databases of Oracle 9i to 11g in a short and give me the result.
  
  Please help me to solve this problem and let me know if you need more information.

  Hi Frank,.

  It is an excellent service. Thanks for you response.
  I want to change the query that... I should get only the name of these data files that are special characters of detention. I don't know how to put it in that condition. :(

  Here's one way:

  SELECT  file_name
  ,       ...     -- other expressions, if you want any
  FROM    dba_data_files
  WHERE   TRANSLATE ( file_name
                    , '?0123456789.ABCDEFGHIJKLMNOPQRSTUVWXYZ\_/abcdefghijklmnopqrstuvwxyz'
                    , '?'
                    ) IS NOT NULL
  

  Among other expressions, you can put in the SELECT clause (if you wish) is a copy of the TRANSLATE function, you had in your message. That would underline exactly what characters rendering invalid file name.

• Bunch of Oracle on the special characters in a string - translate?

  How to remove special characters in a string, it can contain. , (space), etc.

  SELECT TRANSLATE('123.456 (90-90)', '', '') FROM DUAL
  

  Basically I want to undress and to compare with the db value.

  WHERE TRANSLATE(TABLE.NUMCODE, '', '')  = TRANSLATE('123.456 (90-90)', '', '') 
  

  Use TRANSLATE, since you're on 9i. For example:

  TRANSLATE (your_string,'X,. #! % @$ ^ & * () _-+=', 'X')

  Removes all the s characters in ', #! % @$ ^ & * () _-+=' of your_string.

  Dear Experts,
  
  Your usual help is needed to resolve the query. My query is ' how to find all special characters such as (% $* & @, ' / +-etc. in a single query?).
  Thank you.

  This can work:

  select * from your_table where replace(translate(your_column,' abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890','x'),'x','') is not null
  

  Above code verifies an ascii and numbers. You can adjust the chain with other characters you want to see (exclude)

• REGEXP_REPLACE problem with special characters in the string

  Hi guys,.
  
  I have had problems using the REGEXP_REPLACE function and I'm trying to find a solution.
  
  The closest I can get is this thread:
  
  Re: How to replace the first occurrence of a substring
  
  and that's only because the solution, I'm trying to achieve is the one suggested. I did ppost my problem there, but because it is answered, I don't have an answer.
  
  I'm doing the following:
  

  select 
    regexp_replace('A*|A*|C11|A1|A*||_|OR|H452|C40|A|A*||_|AA|1151|G31|A1|A||_|EX|8HI01|H11|A1|A||_|OCR|H421|B11|A|||_|OR|H434|C11|A|||_|AQA|9990|E10|EP|||_|AA|2151|G31|A|||_|',
    '^(\w|-)*\|{1}',null)
  from dual

  Basically, replace it does not work, because the first part of the string contains an asterisk. If you delete the Asterix, then replace it won't work.
  
  How can I get around this? I can't use a regular REPLACEMENT as I want to remove the first instance of A * and not all instances of the A.
  
  Help, please! I don't know what to do... probably, I mustn't start a loop through the string?
  
  Thanks in advance guys!

  To decode your regular expression, it seems that you want to remove A * | and not just A *.

• Replace special characters in a string

  Let's say that someone copies the list as follows and the glue in a Javascript dialog box:

  302304

  305678

  245675

  How do I manipulate the string so that it reads:

  302304 305678 245675

  In other words, how to replace manual line breaks in a string with spaces?

  Thank you!

  It's the cleanest method that you are looking for:

  /[\n\r]/
  

  In this case, even a simple \s would work, but it's maybe not what the OP...

• JSON format - Date and special characters

  Hi all

  I had a JSON server in which, I have a few text values and date.

  1. How can I convert special characters to normal String.e.g. Comma etc. ?
  2. How can I convert long date, a string in the format e.g. "1345670466960-0400"?

  I really appreciate any help above.

  Solved... Where the above closure. For others, I will post the solution.

  Special characters-

  QByteArray buffer(bufSize, 0);
  int read = reply->read(buffer.data(), available);
  //response = QString(buffer); -- Wrong way to convert the bytes.
  response = QString::fromUtf8(buffer); // right way, so special character handled itself.
  

  Day fromatting - for example "/ Date (1345670466960-0400).

  QString getStringDate(QString k){
      QDateTime date = QDateTime::fromTime_t(getDate(k));
      QString strDate = date.toString("MM/dd/yyyy HH:mm:ss");
      return strDate;
  }
  long getDate(QString k) {
      long rc = 0;
      QString v = k;
      if (v.length() > 0 ) {
          int b = v.indexOf("/Date(");
          if (b >= 0) {
              b += 6;
              int e = v.indexOf(')', b);
              if (e > b) {
                  QString s = v.mid(b, e);
                  int sign = 1;
                  if (s.indexOf('-') > 0 || s.indexOf('+') > 0) {
                      sign = s.indexOf('-') > 0 ? -1 : 1;
                      e = sign < 0 ? s.indexOf('-') : s.indexOf('+');

• Special characters in the variable string sent from php.

  Hello. Assuming that I have send a php string variable in flash:

  AS3:

  var MyImportedString:String;

  var variables_page_text:URLVariables = new URLVariables();

  var varSend_page_text:URLRequest = new URLRequest("MyPHP.php");

  varSend_page_text method in the group URLRequestMethod.POST;

  varSend_page_text data in the Group variables_page_text;

  
  

  var varLoader_page_text:URLLoader = new URLLoader;

  varLoader_page_text the dataFormat group pouvez;

  varLoader_page_text. addEventListener (Event.COMPLETE, var_comp_page_text);

  varLoader_page_text. load (varSend_page_text);

  ( function var_comp_page_text() event: Event(): void {}

  MyImportedString = event.target.data. $myvariable;

  }

  PHP:

  <? PHP

  header (' Content-Type: text/html; charset = utf - 8');

  $mystring1 = "some text &";

  Print "$myvariable =" . $mystring1;

  ? >

  I noticed that the special '&' residing inside the string character, throws an error: #2101: the string passed to URLVariables.Decode must be a query string URL-encoded containing name/value pairs.

  My first thought was, it has something to do with the html entities, but other entities (such as <> or """) do not throw any error. In addition, the use of php functions like htmlentities(). or html_entity_decode(); makes no difference in this case:

  Print "$myvariable =" . htmlentities ($mystring1);

  or

  Print "$myvariable =" . html_entity_decode ($mystring1);

  I also noticed that the characters such as '%', ' ^', '+' appear at all;

  What it means? Any ideas?

  Reagards.

  This function generally works pretty well:

      function flash_encode($string)
    {
       $string = rawurlencode(utf8_encode($string));

  $string = str_replace("%C2%96", "-", $string);
         $string = str_replace("%C2%91", "%27", $string);
         $string = str_replace("%C2%92", "%27", $string);
         $string = str_replace("%C2%82", "%27", $string);
         $string = str_replace("%C2%93", "%22", $string);
         $string = str_replace("%C2%94", "%22", $string);
         $string = str_replace("%C2%84", "%22", $string);
         $string = str_replace("%C2%8B", "%C2%AB", $string);
         $string = str_replace("%C2%9B", "%C2%BB", $string);

  return $string;
