Application Express :: Blob Downloaded Image Not Displayed
Dec 18, 2012
We 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....

I have just created the basic employee information form in which i upload the photograph of the employee. The photograph gets uploaded but it does not display properly. I have already referred the sample database application to display the image. Moreover, i have followed the same steps as it is used to display the product image in that application. Still i am unable to get result. I am getting following output:
<img src="apex_util.get_blob_file?a=35682&s=101496289174102&p=15&d=10639237623242912156&i=10639236703270912154&p_pk1=21&p_pk2=&p_ck=FCA12832591A1C706D76FDD589E551A2" />

When a format mask is applied to numeric field in an Interactive Report, e.g. 999G999G999G999G999G990, search operations from the Search Bar do not match any entries if the mask characters are included. For example, the data value from the database is: 2251343000. When the above, example format mask is applied, this is displayed as 2,251,343,000. However, if the user enters 2,251,343,000 in the search bar (which would be the natural thing to do), nothing matches. On the other hand, if the user enters 2251343000, a match is found.
This seems like counter intuitive behavior to me since the whole point of the tool bar is to allow "self-service" for the user. Training them to remove commas, dollars signs or whatever is not very popular.

Env: APEX 4.1
For example, initially I created the reprot source as select c1, c2, c3 from t; later I added c4. But i was unable to figure out how to make c1, c2, c3, c4 become default displayed columns. I always have to click Action -> Select Columns, then move C4 from "Do not Display" to "Display in Report".

I am developing an apex application using the apex cloud (apex.oraclecorp.com). I am using the DB link to show the data on APEX UI. I have a blob data which is stored in the remote DB, and I want to display the BLOB data as text on a popup or a new page or a download link. I tried using display only item but APEX throws an error saying that remote DB is not supported. Also, It would be great if I can just show a download link on the UI for the BLOB data, again when I try to select the format as BLOB in the column attributes, When I give the table@dblink as BLOB table I get an error saying that "table@DBLINK not found". Is there any way to display the BLOB data as text or download it which is present in my local DB?

I have noticed several posts here on the topic of image path in APEX.I have just upgrated to APEX 2.2.3,Uploaded an image via the application into the default images are, nothing too fancy,Trying to show this image in the logo area of the application, The image will not show.
This is hosted with a hosting firm, so I am not running the software on my own, just administering the workspace.In application user interface, I have the Logo field set to:
<img src="#APP_IMAGES#KKC.jpeg" type="image/jpeg" />I tried "#WORKSPACE_IMAGES#
also, and same issue.When I want to assign an image to a list item, it works because I simply have to pick/select from available images in the folder.But in this case, there is no selecting of the image as an option. I must supply the path.Read the documentation, and some cases here, and still no solution. This seems to be a known issue.

select id, flow_image_prefix from apex_040100.wwv_flows; all application now have the prefix /i4/ but when I go to http://myserver:8080/apex nothing is displayed !!!!
when i change */i4/* back to */i/* everything is back to normal...

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.

I have just started using Oracle Application Express 11g. On my new attempt I am able to develop a table, report and a form, but I am not able to display picture image on the form though the browse link is active.
I can load the file name from the location folder to the form but it does not display. When I click on APPLY CHANGE then everything disappears. My main problem is how to successfully configure the settings for image display.

I have created a few flash charts using APEX4.2. Is there a way for the user to view the chart and then email it as an inline image to someone? I know that the user can save the chart as PDF file, then send it as an attachment via Outlook ( or similar system), but can I integrate these manual steps to one ( template), similar to the IR report's download feature ?

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 needed to create a page on my existing APEX application that would allow the user to upload a file, I followed an online tutorial where the user had created a dummy table and inserted CSV File inserted through APEX into the table. Following that simple example I am able to load the simple CSV file (from tutorial) into a dummy table (from tutorial) but when I attempt to insert actual/dummy data into my actual database (which has a lot more fields of different types), using the exact same process, I am unable to do so.
Ironically, I am unable to insert even dummy values despite the fact that I have been able to insert the same dummy values using SQL Developer. Icing on the cake is that APEX does not produce any error, this lack of debugging feature (especially line by line debugging) is such a pain. Just to add, I can load the values into an Array and can successfully print the delimited values off the array but am still unable to insert the same values into my table. Here is the table that I am attempting to insert into (actual names replaced by Dummyxx):
CREATE TABLE "TABLE"."STG" (
"DUMMY01" NUMBER,
"DUMMY02" NUMBER,
"DUMMY03" NUMBER,
"DUMMY04" DATE,
"DUMMY05" CHAR(3 BYTE),
[code].........
And here's the insertion process:
DECLARE
v_blob_data BLOB;
v_blob_len NUMBER;
v_position NUMBER;
v_raw_chunk RAW(10000);
v_char CHAR(1);
[code]..........
If I run a process to produce the output of the data array onto the screen, the values displayed are in the pattern desired.
Inserting Dummy values instead of values from the Array (v_data_array) to test
EXECUTE IMMEDIATE 'insert into TABLE.STG (DUMMY01, DUMMY02 ..... DUMMY65)
VALUES (
60040,
5,
TO_DATE("14-Dec-12","DD-MON-RRRR HH:MI:SS"),
"ABC",
"ABC",
60,
"11DEC1201",
"331",
"SCOTT TIGER",
"MARKETING",
[code].......
Note that all the the CSV does not contain all the fields, the CSV files that are expected to be entered into the system contain 65 Fields whereas the Table has 73 Fields. Also note that the process runs fine through SQL loader that is invoked through a different server which I need to release and hence the attempt to load the table this way. Also, the procedure on the SQL Loader server is quite complex and involved JAVA+Unix Shell Scripts etc. which I would prefer to avoid.
