HOW IT SAVES IMAGE IN TABLE?

Hi friends,
I have 1 table test with fields:
eid number,
e_pict long raw.
I have saved images through a form to the table from a file.
after saving I tried to see the table's data:
SQL> SELECT * FROM TEST;
EID E_PICT
123 4
20
789 4
456 4
4897 4
128 5
6 rows selected.
I've found for same type of image (say .gif) the E_PICT value is same, only when change the image type the value changes and does not depend on path or filename. Then how Oracle keeps track of exactly which image is saved?
Pls help me.
Regards,
Pragati.

What version of Oracle, and what are you hoping to do with the images?
Oracle has something called interMedia which is included free in the Standard and Enterprise editions of the database. It handles audio, image and video.
The documentation even includes "The interMedia PL/SQL Web Toolkit Photo Album sample application" which demonstrates how to perform the following operations:
*Use the interMedia image object type to upload, retrieve, and process media data stored in Oracle Database.
*Combine the image metadata methods of interMedia with the XML document management capabilities of Oracle XML DB and the full-text indexing and search features of Oracle Text to create a solution that can extract, store, and search metadata that is embedded in binary image files.
*Collect new metadata from a user, format the metadata into an XML document, and store the document in the binary image.

How to save images to table using stored procedures?

hi all,
i created a stored procedure
create table members ( id number, name varchar2(30), avatar blob );

begin
insert into members values ( id, name, avatar);
commit;
end;i have 3 items in page..
1. Hidden -> P1_ID
2. Text field - > P1_NAME
3. File Browse - P1_AVATAR
but when invoking the procedure in Processes like
begin
add_member ( id => :P1_ID, name => :P1_NAME, avatar => :P1_AVATAR );
end;i get an error
1 error has occurred
* ORA-06550: line 3, column 3: PLS-00306: wrong number or types of arguments in call to 'ADD_MEMBERR' ORA-06550: line 3, column 3: PL/SQL: Statement ignoredcan anyone tell me why it errors out?
thanks

Did you do as fac586 suggested:
create table members ( id number, name varchar2(30), avatar blob );
create or replace add_ member ( id number, name varchar2, avatar blob )
is
begin
insert into members values ( id, name, avatar);
commit;
end;should be something like:
create table members ( id number, name varchar2(30), avatar blob );
create or replace add_ member ( id number, name varchar2, avatar blob )
is
begin
insert into members (id, name, avatar) values ( id, name, avatar);
commit;
end;You need to specify the columns of the table that you will be inserting values into.
Also, you should probably rename the parameters of your procedure so you can differentiate between the parameters, and the database columns.
i.e.:
create or replace add_ member ( p_id number, p_name varchar2, p_avatar blob )

How to save image in database

hi ,
I am developing a application. i want to upload image with person's details and save it to database. How to do this? I hv got tutorials for uploading image but want to know how to save it to database table along with person's details.
Thanks in advance.

1.Go to transaction SE78.
2.Select tree menu: Form Graphics -> Stroed on Document Server -> Graphics General Graphics -> BMAP Bitmap Images
3.Select <IMPORT> to import bitmap image file to SAP. System will popup screen for input file information and target name.
4.Select <Tick> After you already input data. System will upload image and return message to tell you success or fail.
5.You can preview the picture that uploaded by select<print prv>
If u want to store the images and retrive it from the server corresponding to the person id then just save the image by person id and code it as per the requirement.
U can save ur images using se78 and also u can c it using TCODE AL11.By navigating thru the exact path u can get the images.

How to insert image into table and to in Oracle 9i intermedia?

Mr Lawrence,
I want to ask something:
I use Oracle 9i intermedia
If i use this script:
CREATE TABLE images (
file_name VARCHAR2(100) NOT NULL,
image ORDSYS.OrdImage
then
CREATE OR REPLACE DIRECTORY imgdir AS 'd:/data';
then
INSERT INTO images (file_name, image)
VALUES ('tree', ORDSYS.ORDImage.init('file','imgdir','tree.jpg' ));
I put tree.jpg in directory d:/data in my hard drive.
Is my tree.jpg file had already get in to my images table?
I'm little confuse, because when i check my table with this script:
select file_name, i.image.getWidth() from images i;
it's show that my i.image.getWidth() for file_name tree is empty.. that mean my tree.jpg doesn't get in to my table.. am i correct?
N also i want to ask how to display to screen all of my image from images table?
Is it posible Oracle 9i intermedia to support display image from table?
How?
thanks Mr Lawrence

-- First step would be to create a directory in oracle and map it to the folder where your image resides.
create directory image_dir as *'c:\image_dir';*
Then you would have to use a procedure to insert the image in your table. SO first create a table to hold the image. Note that you have to use a BLOB to insert the image.
CREATE TABLE test_image
ID NUMBER,
image_filename VARCHAR2(50),
image BLOB
Now let's write the procedure to insert the image in the table above.
CREATE OR REPLACE PROCEDURE insert_image_file (p_id NUMBER, p_image_name IN VARCHAR2)
IS
src_file BFILE;
dst_file BLOB;
lgh_file BINARY_INTEGER;
BEGIN
src_file := BFILENAME ('image_DIR', p_image_name);
-- insert a NULL record to lock
INSERT INTO temp_image
(ID, image_name, image
VALUES (p_id, p_image_name, EMPTY_BLOB ()
RETURNING image
INTO dst_file;
-- lock record
SELECT image
INTO dst_file
FROM temp_image
WHERE ID = p_id AND image_name = p_image_name
FOR UPDATE;
-- open the file
DBMS_LOB.fileopen (src_file, DBMS_LOB.file_readonly);
-- determine length
lgh_file := DBMS_LOB.getlength (src_file);
-- read the file
DBMS_LOB.loadfromfile (dst_file, src_file, lgh_file);
-- update the blob field
UPDATE temp_image
SET image = dst_file
WHERE ID = p_id AND image_name = p_image_name;
-- close file
DBMS_LOB.fileclose (src_file);
END insert_image_file;
Now execute the procedure to insert the image.
EXECUTE insert_image_file(1,'test_image.jpg');
Thanks,
Aparna

How to Save image in a text to my photos

How do I save the photo in a text message to my iPad air photos?

Tap the image in Message. (If you touch too long it brings up the: Copy; Other... menu instead)
This blows the image up to full screen.
Touch the image again to get menu options.
In the top right corner, tap the box with the up arrow. One choice is Save Image. Touch it to save to your camera roll.
In the top left corner, the three-line menu shows you all the photos in the message string, and some metadata like image size and camera title/image number.
This is in IOS 7.1.1 on an iPad, and should work on iPhone and Touch also.

How to save Image from binding FlipView?

I bind 4 images in my FlipView, how save an binding Image to Picture Library;
<FlipView Name="display1" ItemsSource="{Binding}" Foreground="#FFE6D52E" HorizontalAlignment="Center" VerticalAlignment="Center
            <FlipView.ItemTemplate>
                <DataTemplate>
                            <Image x:Name="image" Source="{Binding Path=Image}" Stretch="UniformToFill"/>

//for me it is hard to save binding files,I cant save any image

Hi Icce cage,
Per my understanding, you bind the path of image to Image control, so you get image path string from display1.SelectItem property. Try finding Image from this path in installation folder and then copy it to Picture library. Please try the following code
snippet.
Custom class to hold the image object.
public class CustomClass
public string ImagePath { get; set; }
public string ImageName { get; set; }
Initial image sources.
private void Page_Loaded(object sender, RoutedEventArgs e)
images = new System.Collections.ObjectModel.ObservableCollection<CustomClass>();
images.Add(new CustomClass() { ImagePath = "/Images/1.png", ImageName = "1.png" });
images.Add(new CustomClass() { ImagePath = "/Images/2.png", ImageName = "2.png" });
images.Add(new CustomClass() { ImagePath = "/Images/3.png", ImageName = "3.png" });
images.Add(new CustomClass() { ImagePath = "/Images/4.png", ImageName = "4.png" });
images.Add(new CustomClass() { ImagePath = "/Images/5.png", ImageName = "5.png" });
display1.ItemsSource = images;
XAML.
<FlipView RightTapped="display1_RightTapped" Name="display1" Foreground="#FFE6D52E" HorizontalAlignment="Center" VerticalAlignment="Center" >
<FlipView.ItemTemplate>
<DataTemplate>
<Image x:Name="image" Source="{Binding Path=ImagePath}" Stretch="UniformToFill"/>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
Save image to picture library.
private async void display1_RightTapped(object sender, RightTappedRoutedEventArgs e)
CustomClass data = display1.SelectedItem as CustomClass;
if (data!=null)
var installation = Windows.ApplicationModel.Package.Current.InstalledLocation;
var imagesfolder =await installation.GetFolderAsync("Images");
var file = await imagesfolder.GetFileAsync(data.ImageName);
await file.CopyAsync(KnownFolders.PicturesLibrary);

How to "Save Image" directly instead of "Save Image As"?

Is there anyway or option to directly save images instead of having to click "save image as" then go into the popup to save the image location? Thank you!

Gingerbread Man made good suggestions.
However you still must "save as" something even if "unnamed001". Windows requires a name and location for each file (whether an image or other file) saved. You can have the same file name in different directories (folders).
You can copy and paste images without saving, in some applications.

How to save image from email to iPhoto

trying to save image attachment from email to iPhoto

What is the problem? What does not work?
Either drag the attachment from the mail to the iPhoto con in the Dock, or ctrl-click the attachment and use the option "Export to iPhoto" from the pop-up menu (in Mail in MacOS X 10.10). Don't remember, if this worked in Mail in Mac OS X (10.5.8), as your signature is showing.

Problem with how FeuerFuchs saves images

FeuerFuchs presently seems to work like this. You load a page displaying an image or images. You like one or more of them and you want to save them. Each time you tell FeuerFuchs to save an image, instead of copying that image from wherever it's stored in order to display it on your screen to the folder you want to save it to, FeuerFuchs re-downloads that image.
Can someone please tell me why FeuerFuchs is programmed to re-download images it's told to save instead of copying them from wherever they're stored in order to display it on the screen? It seems like that only serves to increase bandwidth usage.

I've got that and it's great for if I want to save all the images from one or more tabs. But it only saves images from entire tabs instead of one out of several images in a tab and the treeview navigation is slower than using the shortcuts I use to jump from one folder to the next.

HOW TO SAVE DATA FROM TABLE A AND TABLE B INTO TABLE C

Hi,
I have a table called EMPLOYEE , GROUP and EMPLOYEE_GROUP
table EMPLOYEE contains emp_id, emp_name, emp_dep and emp_level

How can I assign many employees to one group?
But each group have the limit number.
My screen would be :
1. search employees based on their department and level
2. assign each employees to a group
*3. save the data into table EMPLOYEE_GROUP (where the process should save the emp_id and group_id into table EMPLOYEE_GROUP)*
Thank you in advance!
