How to cast a BLOB to OrdImage

Hi,
How can I cast or convert a BLOB to OrdImage? For example,
<import...>
public class ConvertBlobToOrdImage {
public static void main(String args[]) throws Exception {
// Load the Oracle JDBC driver:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database:
Connection conn =
DriverManager.getConnection(<"Your database connection">);
conn.setAutoCommit(false);
// Create a Statement:
Statement stmt = conn.createStatement();
String query = "SELECT blob FROM image_t where image_id = 1";
OracleResultSet rset = (OracleResultSet) stmt.executeQuery(query);
rset.next();
OrdImage imageProxy = (OrdImage) rset.getCustomDatum(1, OrdImage.getFactory()); // <-- java.lang.ClassCastException: oracle.sql.BLOB
rset.close();
int height = imageProxy.getHeight();
int width = imageProxy.getWidth();
System.out.println("Image Dimension: " + height + " x " + width);
System.out.println("Image Mime Type: " + imageProxy.getMimeType());
TIA,
Henry

HOW TO CAST NVARCHAR2 TO BLOB

Hello
i must stock my data to a nvarchar2 data (unicode) and i must also make full text search on this column, oracle does not support full text search on unicode data, so i have decided to stock my unicode data to a blob clomun, after i can create a full text index and search data.
my problem is how to cast nvarchar2 to blob in oracle. i'm using a vb program with adodb to write and read data from the db and i must write the data (unicode text) in the blob column using the right cast which allows me to use directly adodb to read information (i have tried this with sql server with a varbinary(max) column and it works : i write a nvarchar data to the verbinary(max) column using the cast function, after, adodb can read directly the information without any explicit cast) is this possible on oracle
thank you for your help

What is your database character set? If it's AL32UTF8 you shouldn't really need to use NVARCHAR2 at all - you can store Unicode data in a VARCHAR2 or CLOB column.
BLOB doesn't seem like the right datatype to use - if it's text you want to index then it should be in a VARCHAR2 or a CLOB column. If you put it in a BLOB then you'll have to explicity tell Oracle not to treat it as a binary document, and you will have to handle all character set issues manually.
I'm afraid I know nothing about VB or ADODB.

How to Get a BLOB Field from JDBC Coding

Hi,
I have written the JDBC Code to get the field values from the Table.
There is a BLOB field in that table.
How to get the BLOB ? What is the return type we should use.
If it is Varchar then we can use rs.getString().
If it is BLOB then what is the return type?
Thanks in Advance

Blob.
You know, people like you really give me the urge to print out several hundred pages of Java API and smack them on their heads.

How to cast an Object into a specific type (Integer/String) at runtime

Problem:
How to cast an Object into a specific type (Integer/String) at runtime, where type is not known at compile time.
Example:
public class TestCode {
     public static Object func1()
Integer i = new Integer(10); //or String str = new String("abc");
Object temp= i; //or Object temp= str;
return temp;
     public static void func2(Integer param1)
          //Performing some stuff
     public static void main(String args[])
     Object obj = func1();
//cast obj into Integer at run time
     func2(Integer);
Description:
In example, func1() will be called first which will return an object. Returned object refer to an Integer object or an String object. Now at run time, I want to cast this object to the class its referring to (Integer or String).
For e.g., if returned object is referring to Integer then cast that object into Integer and call func2() by passing Integer object.

There is only one way to have an object of an unknown type at compile time. That is to create the object's class at runtime using a classloader. Typically a URLClassloader.
Look into
Class.ForName(String)

Hi Smirt
You could do:
ClsMyTypeCollection* operator->() {
returnthis;};
// operator pointer to ->
operatorClsMyTypeCollection*()
{returnthis;};
public:
vector<ClsMytype>
m_t_Col;//??
The last line with "vector<xClsMytype>
m_t_Col;". It compiles but I doubt that is what you want.

How to modify the blob size, or how to set the size?

i want to know how to modify the blob size, or how to set the size?
what's the default size of blob?
Thanks in advance.

Blob datatype can contain binary data with a maximum size of 4 GB.
when you enter 10kb file, the database will only use 10kb to store the file (depending on block size etc)
if you want to modify the blob size, you may do like this:
SQL> create materialized view t_mv refresh fast on commit
2 as select id, dbms_lob.getlength(x) len from t;
Materialized view created.
SQL> alter table t_mv add constraint t_mv_chk check (len < 100);
Table altered.

How to cast an object in JSF?

I am working on a travel application. A user can have several bookings and a booking can have several components. A component can be either air or hotel. I want to list the user's bookings on the client using JSF datatable.
<h:dataTable var="component" value="#{booking.components}">
Now depending upon the class of component I need to present different information.
My question is how to cast the variable in JSF ?
Thanks

You can use the String value of Object#getClass()#getName() to lookup the classname and evaluate it in the 'rendered' attribute.
Basic example:
package mypackage;
public class Animal {}
package mypackage;
public class Cat extends Animal {}
package mypackage;
public class Dog extends Animal {}
package mypackage;
public class Fish extends Animal {}MyBeanpublic List<Animal> getList() {
    List<Animal> animals = new ArrayList<Animal>();
    animals.add(new Dog());
    animals.add(new Cat());
    animals.add(new Fish());
    return animals;
}JSF<h:dataTable value="#{myBean.list}" var="item">
    <h:column>
        <h:outputText value="It's a Cat" rendered="#{item.class.name == 'mypackage.Cat'}" />
        <h:outputText value="It's a Dog" rendered="#{item.class.name == 'mypackage.Dog'}" />
        <h:outputText value="It's a Fish" rendered="#{item.class.name == 'mypackage.Fish'}" />
    </h:column>
</h:dataTable>As far there is no way to cast objects in JSF.
Edit
If you find it useful, move the classname request to the superclass:
public class Animal {
    public String getType() {
        String className = getClass().getName();
        return className.substring(className.lastIndexOf('.') + 1);
}Which makes life easier without struggling with package names:<h:outputText value="It's a Cat" rendered="#{item.type == 'Cat'}" />
<h:outputText value="It's a Dog" rendered="#{item.type == 'Dog'}" />
<h:outputText value="It's a Fish" rendered="#{item.type == 'Fish'}" />Message was edited by:

How load File as Blob in Oracle Table?

How load File as BLOB in Oracle Table?

Ah so nice, a FAQ, by someone who can't use online resources!
Any explanation why Google is broken for you?
Here is the code I use to load a jpg.
procedure upd_portrait(p_person_id in number, p_file_name in varchar2) is
l_blob blob;
l_bfile bfile;
begin
update person
set portrait = empty_blob()
where id = p_person_id
returning portrait into l_blob;
l_bfile := bfilename('MY_IMAGES', p_file_name);
dbms_lob.fileopen(l_bfile);
dbms_lob.loadfromfile(l_blob, l_bfile, dbms_lob.getlength(l_bfile));

How to cast ArrayList to ....

Hi,
I got an ArrayList and its values are (1,2,3)
List tempList = new ArrayList();
tempList.add("1");
tempList.add("2");
tempList.add("3");
I am wondering how to convert it to an int [] array.
int [] tempInt;
I know that I can do this : tempList.toArray
but I don't know how to cast this to int[] type of array
(note: not integet [] , just int[])
Can anyone help? thanks a lot.

Note: It would be much more efficient to use the wrapper classes for storing primitives in a Vector/ArrayList/LinkedList/... :
tempList.add(new Integer(1));
tempList.add(new Integer(2));
tempList.add(new Integer(3));
(getting the array as an int[] still requires a for-loop)

How to cast object type to integer type?

Hi,
Object [] temp;
Int [] value;
How can I assign temp to value? (value = temp?)
In other words how to cast array of type object to array of type integer?
Thanks a lot.

Hi,
Object [] temp;
Int [] value;
How can I assign temp to value? (value = temp?)
In other words how to cast array of type object to
array of type integer?
Thanks a lot.That my friend, is (sometimes) illegal. other times use
value = (Integer[]) temp;
Pray that temp is holding an Integer array so that you dont throw a runtime exception.
I am assuming you know the diff between "int" and "Integer".
