how to display image via 'display image' item, using SQL?
Hi
how can I display image via 'display image' item?
the image is stored as BLOB in my database table, that can be retrieved as
SELECT PHOTO FROM EMPLOYEES WHERE ID_EMPLOYEE = ...
but this does not seem to work , or I don't know where to put this SQL query?,
because there are two available fields: in SETTINGS | Based on SQL statement,
or in SOURCE | SQL Query (return single value) ?
(see attached)

Type = PHOTO
Used = Always, replacing...

update:
I tried the trick with
SELECT dbms_lob.getlength(PHOTO)
FROM EMPLOYEES
WHERE ID_EMPLOYEE = ...
but still doesn't work...
btw. I can reproduce - displaying photos in a static report described here
Brendan Tierney - Oralytics Blog: How to Display a BLOB image in an APEX Report
that is also usable, except that I don't know how to set some "fixed size" to the cell /'cell width' column attribute doesn't work/

I would suggest that you create an application on OTN first.

I have literally just done this today, and as far as I can see you've done it correctly, assuming your photo column really is an image blob. My SQL is in the 'settings' SQL Statement & is almost identical to yours. I haven't changed anything in the 'source' section from the defaults.
Oh, and I set the width in 'Custom Attributes' using: width="150"
Cheers/

Hi,
You should use
Based On -> Blob column return Sql Statement
& write your query below that in
SQL statment -> SELECT PHOTO FROM EMPLOYEES WHERE ID_EMPLOYEE = ...
Hope this will solve your problem.
Do let me know after do try this.
Thank you.

thank you all!,
I figured out that on blank new page it actually works!...
(it doesn't work in one of my particular page, so probably there is some other bug... but I leave it for later now)
thanks
