I have a table containing records with a field representing a png image that is encoded as base64 text. The procedure responsible for creating the record receives the base64 information in a parameter of type CLOB. It then inserts it in a field of same type on the record. I want to transform the CLOB data into an image and display it back on the form.

I am using developer 10.1.2.0.2 I have created a table to store the BLOB, which is jpg image originally. And I have uploaded those image into the database successfully.
Table name: images
img_id number
img blob
I know that I can set display one image each time if I create the image icon on the form using "data block wizard"..But the problem is that I cannot display multiple image on a form at the same time
I have a blob column in one table. I need to show it in my form (6i). If i put an image file in the column, it works (because i show it in a Image item type) but if i put a text file in the blob column, it does n´t work.
View 4 Replies View RelatedI have a table named PRODUCT (ID Number , ProductImage BLOB). I have inserted some records in. I want to create a form for user to view this table.
When I create Data Block, in Data Block Wizard, if I select option 'Table or View' to retrieve data, it's ok (Data type of item ProductImage is Image, when I run form and query, it display image normally).BUT, I want to retrieve data from stored procedure in a package. This is my package
PACKAGE my_pkg IS
TYPE my_rec IS RECORD
(
myID PRODUCT.ID%TYPE,
myImage PRODUCT.ProductImage%TYPE
);
[code].....
I select option 'Stored Procedure' in Data Block Wizard, then select my stored procedure (my_pkg.Do_Query). Next I choose 2 columns from my stored procedure (ID, ProductImage). The wizard still applys data type of ProductImage as Image. I finish Data Block Wizard and Layout Wizard... run form, query and an error message display:
FRM-40364: The data type of item 'ProductImage' does not match the corresponding column in the stored procedure.
I try to change 'myImage PRODUCT.ProductImage%TYPE' -> 'myImage BLOB' in my package but still get that error.

View 3 Replies View Related I have a db field "image" of type BLOB and I save the contents to a file on a local folder c: example.bmp.
I found numerous examples
BEGIN -
Get LOB locator
SELECT image INTO l_blob pc_immagini_blob FROM WHERE code = WCI;
- Open the destination file.
l_file: UTL_FILE.fopen = ('C: Temp', 'EXAMPLE.BMP', 'w', 32767); -----> error
The db is not local but on an application server, the image must be saved to c: the client.
We are using 10G Forms and Reports against a 8I database (DB1) which has a link into another 8i Database (DB2).
DB2 has been upgraded to 10G. The application works fine but when I try to compile the forms in form builder I get an "ORA-03115, unsupported network datatype or representation." error.
The error occurs where the code in the form references the link directly. Other code where we created views to hide the link name works fine. BTW Same code works fine in SQL Plus 10G & Toad.
I have tried changing the type of variables & different columns but that did not work.

View 6 Replies View RelatedWe have apex application with one record report that shows image.We use database procedure to show image.And call it in apex like:
'<img src="show_image?p_id=' || NVL(dp.id, 0) || '" height="200" width="200" />' as image
But the image is not shown. We only see broken image icon.With right click on broken icon, we can save it and it's actual image we want to display.
If we call procedure like: URL.....
If we use the same procedure on another table with images which are smaller, then the image is shown.Minimum image length in table A is (DBMS_ LOB.getlength (file)): 105243..Maximum image length in table B is: 1702. URL....
Recently I came across this issue, which gives me an error as following.
ERROR:
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 4907, maximum: 4000)
Now I am running a very simple query against one of the View in our Database.
Query is:
Select Prj_Num,
PM_Comments
From ProjectDetails
Where Rel = ‘2008 10’
What I have discovered so far is one of the field in this view name “PM_Comments” has more than 4000 bytes of information in it, Which is not supported by tools I have available on my computer. I have Oracle SQL Plus, SQL plus Worksheet, Access and Excel installed on my machine. DBA related to this database are stating that the field is working fine and query is executing without error since they are using TOAD for SQL, which does have capabilities to read more than 4000 bytes.
What I have figured out so far is “PM_Comments” is a LOB and SQL plus is having trouble reading this information more than 4000 bytes in one field of information.Because of this diagnosis, I have tried using following queries but it did not useful either.
Select Prj_Num,
Substr (PM_Comments, 1, 4000)
From ProjectDetails
Where Rel = ‘2008 10’
Select Prj_Num,
DBMS_LOB.Substr(PM_Comments, 4000, 1)
From ProjectDetails
Where Rel = ‘2008 10’
But both of the above mentioned queries did not work either. and I get the same ORA-22835 Error.I do not need all of the information in “PM_Comments” field, I only need about first 1000 characters of it.
