Application Express :: How To Display Blob As Text
Jul 9, 2013
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?
Oracle 11.2; application express 4.1...I have a table with a unicode clob column into which I insert descriptive text. Within these text entries I have inserted CR/LF (00D00A). However when I display the text entries in a report, the text streams instead of appearing with separate lines.
My report statement: select text_entry_dt, entry_authy_nm, entry_text from obj_text where obj_id = :P41_FIND_ID and text_type_cd = 'DES'
hat to do to obtain line separation within the entry_text content?
Have got basic form on a table and have a textarea which holds Notes added by user.
So Notes database field is updated on Save / Apply changes button being pressed.But would really like any text added / appended to the Notes field to be prefixed by userid and date / timestamp.
Is it possible via dynamic actions or Javascript to have any new text added / typed to be auto prefixed as per above.
Would only want the first key press in the filed to trigger the auto-prefix and if added text was deleted then the auto prefix to be deleted as well ?? If user doesn't press Save / Apply changes obviously want to leave existing Notes as is.
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 am using the below function to return a blob (CSV) content, this is working fine..But i need to modify this function to display headline for the report and fixed width column in CSV ( then user no need to expand the each and every column ).
create or replace function GET_BLOB ( p_query varchar2 ) return blob as
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):
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.
In my project, I implement file's upload and download function by "BLOB Support in Forms and Reports" of official development document Advanced Programming Techniques When user click the BLOB column to download file, I want to trigger an action to update one table for counting this file is downloaded one more times. But I can not find any "dynamic action" about this Blob column of Report.
I try to find out how export data from table to Excel file format and save the result to BLOB field in some other table.I know how to download report from Page by submit, but I need to process data and instead of returning result to user as Excel file - save it in BLOB.
Also I found implementation on JAVA for the issue but actually I wanna study out - Is it possible to resolve this issue by PL/SQL and APEX API methods?
In Application Builder, is there a way to searching the application and replacing text within it?
I have an application item named "FORMAT_TYPE1". I would like to perform a find and replace action (just like a word processor) where any part of the application that has name or text "FORMAT_TYPE1" in whole or in part is replaced by the text "FORMAT_CATEGORY1". For example:
The find/search would do it in any attribute, source code in the application. There is only a Search Application feature, which is useful in identifying places, but lacks any replace function. Is there something else that will do this, besides exporting, editing the source code in a text editor, and then importing the application again?

Just installed 4.2.2.00.09 and imported a workspace and an application. Worked fine.I noted a page display difference when compared to the exported application (4.1.0.00.32). I have (so far) found this:If I have a button with Pre Element Text set to <div class="dummy"> and Post Element Text set to </div>, Apex generates an extra div around it all.If my button was named P1_SUBMIT I end up with
I would like to let the customer edit the item help text. Is it possible to retrieve item help text from my own custom database table based via a PLSQL function call or something similar?
We have recently upgraded to apex 4.2.1 from 4.1. After this, we get a strange stopping issue that the rich text editors clear all their values once the page is submitted. This happens only in Firefox and Chrome, but works just fine in IE. Have you ever noticed and had a solution for this?
how to dynamically populate text fields.For eg, i have a lov with employee no, as soon as a no is selected next text field with employee name will be populated.
i encountered a big problem after upgrading Apex from 4.1 to 4.2.2. On an application page there is a Text Area which will be read and processed after clicking a button. I didn't want a refresh of the page and did it with a dynamic action.All this worked like a charm with 4.1. Since the upgrade, the value of the Text Area is always returned as null while processing the dynamic action, but the value is filled by the user!When i change the type of the Element to Rich Text Area everything works fine, but i don't want this because i don't want HTML in the corresponding table. Is this a bug? How can i workaround it?
In my application, I have SSO authentication. However, I also want to restrict access to certain pages (tabs). What would be the best approach for this? Secondly, How can we hide/display tabs in the application?

I am using APEX 4.0, my regions need to be displayed at "Display Point: Display Template Body 2" in column 2.I have 2 regions I want displayed horizontally, side by side.I want to use a parent region to contain them. I create my parent region, called it A, template = Reports, assign it to sequence = 10.I create my 2 sub region (B) and (C), sequence 20 and 30, template = Navigation, picking parent = A.By default, B displays above C. URL....
I copied the Navigation template, creating a new one called NAV2 and added this in the sub-region template section:(this cut/paste) doesnt display well here: it is the exact DIV begin/end block as posted above.
div style="float: left;" #SUB_REGION# div
I changed regions (B) and (C) to use template = NAV2, without any change in display behavior.I read further in the above post where it was recommended to reset the clear property, so I changed the above style like to: style="float: left;clear:none;".
