Why is this working:
and this not:
case when function1( p1, p2 ) = 'N' then '<img src="#APP_IMAGES#1.jpg" title="1">' else '<img src="#APP_IMAGES#2.jpg" title="1">' end nv
Function1 returns Y or N, Function2 returns the same img-tag as in the 'case when' (<img src="#APP_IMAGES#1.jpg" title="1">). The first statement shows the image correct, the 2nd way does not show the image (red cross).
function2( p1, p2 ) images
Report columns are 'Standard report column', when I change that to 'Display as text', I see the right img-tag.
Does anyone know why this is not working?

In classic report, The best way to do this is change the function to just return the name of image i.e. 1.jpg
And in the report column attributes add a derived column with Display As set to Standard Report Column and in HTML expression add <img src="#IMAGES#"/>
OK. It's an interactive report by the way...
But I wanted to use the function to return more than one image-tag. It will be a list of images, that's why I want to use a function, the list of images is dynamic, so:
<img src="#APP_IMAGES#1.jpg" title="1"> <img src="#APP_IMAGES#2.jpg" title="2">

But I wanted to use a function because I want to show more than one image. The function will return a couple of <img-tags>, so:
<img src="#APP_IMAGES#1.jpg" title="1"> <img src="#APP_IMAGES#2.jpg" title="2"> <img src="#APP_IMAGES#5.jpg" title="5">
@Tom, I think I do not understand your comment...
Exactly as VC showed, that is what i meant. Pass in an extra parameter.
For example, this function
And suppose this is the sql
CREATE OR REPLACE FUNCTION get_images ( p1 IN VARCHAR2, p2 IN VARCHAR2, p_app_images IN VARCHAR2 ) RETURN VARCHAR2 IS lImageList VARCHAR2(2000); BEGIN FOR i IN 1..5 LOOP lImageList := lImageList || '<img src="' || p_app_images || i || '.jpg" alt="' || i || '" >'; END LOOP; RETURN lImageList; END;
When apex parses the SQL, it will substitute #APP_IMAGES#, and would result in your function being called with the correct value.
SELECT get_images('param1', 'param2', '#APP_IMAGES#') FROM DUAL
For example, it would run this after substituting:
SELECT get_images('param1', 'param2', '98484C84E98468C464E894C984A47B867') FROM DUAL
