Converting a Clob to a String

I've had a search around for ways to do this on the forum, but most of the posts only deal with the conversion of a String to a Clob.
Is this conversion possible and does anybody have any pointers or know how to perform it?
Thanks for your time,
Tom.

what's wrong with doing this:
Clob c = rs.getClob("clobcol");
String cValue = c.getSubString(0, c.length());

Cannot convert type class java.lang.String to class oracle.jbo.domain.Clob

Cannot convert type class java.lang.String to class oracle.jbo.domain.ClobDomain.
Using ADF Business Components I have a JSFF page fragment with an ADF form based on a table with has a column of type CLOB. The data is retrieved from the database and displayed correctly but when any field is changed and submitted the above error occurs. I have just used the drag and drop technique to create the ADF form with a submit button, am I missing a step?

The workaround is to add a custom converter class to your ViewController project like this
package oow2008.view;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import oracle.jbo.domain.ClobDomain;
import oracle.jbo.domain.DataCreationException;
public class ClobConverter implements Converter {
     public Object getAsObject(FacesContext facesContext,
                               UIComponent uIComponent,
                               String string) {
       try {
         return string != null ? new ClobDomain(string) : null;
       } catch (DataCreationException dce) {
         dce.setAppendCodes(false);
         FacesMessage fm =
           new FacesMessage(FacesMessage.SEVERITY_ERROR,
                            "Invalid Clob Value",
                            dce.getMessage());
         throw new ConverterException(fm);
     public String getAsString(FacesContext facesContext,
                               UIComponent uIComponent,
                               Object object) {
       return object != null ?
              object.toString() :
              null;
}then to register the converter in faces-config.xml like this
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee">
<application>
    <default-render-kit-id>oracle.adf.rich</default-render-kit-id>
</application>
<converter>
    <converter-id>clobConverter</converter-id>
    <converter-class>oow2008.view.ClobConverter</converter-class>
</converter>
</faces-config>then reference this converter in the field for the ClobDomain value like this
          <af:inputText value="#{bindings.Description.inputValue}"
                        label="#{bindings.Description.hints.label}"
                        required="#{bindings.Description.hints.mandatory}"
                        columns="40"
                        maximumLength="#{bindings.Description.hints.precision}"
                        shortDesc="#{bindings.Description.hints.tooltip}"
                        wrap="soft" rows="10">
            <f:validator binding="#{bindings.Description.validator}"/>
            <f:converter converterId="clobConverter"/>
          </af:inputText>

Need to convert a long into a string, please

hi there
i need to convert a long into a string. can i just cast it like this:
(String)longNumber = some function that returns a long;

Why not just use Long.toString()? If you start with a long value, you can create a Long object and get it's value as a String.

How can I convert an ArrayList to a String[]

Hi,
How can I convert an ArrayList (only with strings) to a String[] ?
I've tried this :
     public static String listToString(List l) {
          StringBuffer sb = new StringBuffer();
          Iterator iter = l.iterator();
          while (iter.hasNext()) {
               sb.append(iter.next().toString());
               if (iter.hasNext()) {
                    sb.append(',');
          return sb.toString();
But what I get is an array of xxxxx@435634 (for example).
Thanks a lot !

Strings are Objects but not all Objects are Strings and at least one of the elements in your List is not a String.

How do I convert an int to a String?

You can also use any of these methods if you need to get more complicated:
Integer.toString(int i)
Integer.toBinaryString(int i)
Integer.toHexString(int i)
Integer.toOctalString(int i)
Integer.toString(int i, int radix)

Converting an int to a string

i want to know how to convert an int to a string .
I have tried toString() but it says can't dereference an int.
any ideas ????
thanks

What I mean by the object being null is, say for example, you have the following method:
   public String combine(Object o1, Object o2){
      return o1.toString() + o2.toString();
   }This method will throw a NullPointerException if either or both o1 and/or o2 are null. If you use it like so:
   public String combine(Object o1, Object o2){
      return String.valueOf(o1) + String.valueOf(o2);
   }This will always work. (I know someone out there would say that this would return a String like "nullnull" if both are null, and so forth and so on, but hey, you get my drift.) I'm also not saying the you can't not check if either o1 or o2 is null before proceeding, so the following also works:
   public String combine(Object o1, Object o2){
      String s = null;    // I'm using this instead of StringBuffer for
                          // simplicity's sake so don't get this wrong
      if (o1 != null){
          s = o1.toString();
      if (o2 != null){
          s += o2.toString();
      return s;
   }As you can see, there's no right or wrong way in programming as long as you achieve the result. The only thing that would matter is how clean your code is, how efficient your code is, and how maintainable your code is.

How do I convert a Variant of type=String to G data? (LV 5.1.1)

I've tried to return a string in the Variant return of a VB function in a DLL. (I want to do this so that I can retain the interface and thus binary compatibility in the DLL.)
When I use the DLL function in LabVIEW 5.1.1 I
get an error in the call library function call (returning). It looks like there is a way to handle this in v 6.0 but I have to use 5.1.1 for this application. Is there a way for LV 5.1.1 to handle a Variant containing a string?
Thanks

Hi Dave,
you can use the type conversion function located under advanced -> data
manipulation to convert the variant into a string.

How to convert a "text variable" to String with plugin

Hello,
I am currently developing a InDesign (CS5) plugin, where I need to manipulate text variable.
From the plugin I want to convert the "text variable" to string (in principle I should use the method "VariableToString (..)" of "ITextVariable")"
My problem is, how to find the text varial from its name (I think I should use the method "FindLocationsUsed(..)" of "ITextVariableSuite") and then convert it to String
I don't know how to use interfaces ITextVariable and ITextVariableSuite
Plugin implemented in C++ language
thank you

Anybody can help in this???

There has been talk about adding these config files, that fixes this kinda problems, to a separate pkg with a helper script you run 32bit programs with.
for quick fix
Link
Grab the 3 pango files, throw them somewhere, edit pangorc to corresponding paths for the 2 other files.
Start program with
export PANGO_RC_FILE="/path/to/pangorc"
program
for the string error, if its iconv
export GCONV_PATH=/opt/lib32/usr/lib/gconv
to previous command
Note, you cant start 64bit programs that use pango/iconv from the terminal you exported the variable.

How to convert an int variable into String type

hi everybody
i want to know how to convert an interger variable into string variable
i have to implement a code which goes like this
Chioce ch;
for(int i=0;i<32;i++)
// here i need a code to convert the int variable i into a string variable
ch.add(String variable);
how do i convert that int variable i into a String type variable??
can anyone help me?

Different methods:
int a;
string s=a+"";or
String.valueOf(int) is the better option because Int.toString() generated an intermediate object to get the endresult

How to convert a CLOB to BLOB

Hi,
Can any one tell me how to convert a CLOB into BLOB? In Oracle 10g there is a function which is converttoblob(). But in Oracle 9i there is no function as such. If i am using Hextoraw() function still then its giving some pointer error. please let me know the solution.

FUNCTION c2b( c IN CLOB ) RETURN BLOB
-- typecasts CLOB to BLOB (binary conversion)
IS
pos PLS_INTEGER := 1;
buffer RAW( 32767 );
res BLOB;
lob_len PLS_INTEGER := DBMS_LOB.getLength( c );

DBMS_LOB.createTemporary( res, TRUE );
DBMS_LOB.OPEN( res, DBMS_LOB.LOB_ReadWrite );

IF UTL_RAW.LENGTH( buffer ) > 0 THEN
DBMS_LOB.writeAppend( res, UTL_RAW.LENGTH( buffer ), buffer );
END IF;
pos := pos + 16000;
EXIT WHEN pos > lob_len;
