Can we disable link in a classic report according to row content?

Question

Hi, guys:
I have a question: I have a classic report, which has a column of link to another page in the same application; the link shows icon of Google map, user can see a Google map of the address listed in the same row of this report by clicking this link. However, some addresses are empty, so we want to disable the link in the column whenever the address in the same row is empty. We tried with all of APEX settings regarding column, but not successful. Could anyone help us on this problem?
so I have a further question is: is there anyway that we can manipulate APEX report content in PL/SQL code?
Thanks.

Hi,Paul:
I tried with your query:
select distinct
(case when (to_char(sl.ADDRESS1_LATITUDE) is null) and (to_char(sl.physical_address_latitude) is null) then null
else '<img src="#WORKSPACE_IMAGES#location.png"\'
end) MAP_link,
......and I set this column with column link text:
#MAP_LINK#
but it shows not the image icon (link is working though), but the text itself as
<a href="f?p=2001:3006:1633012192639501::NO:RP:YES:28F8F2C91B88<a href="f?p=2001:3006:1633012192639501::NO:RP:YES:4B58FD640A235491C077B36E20B0409A">&lt;img src="wwv_flow_file_mgr.get_file?p_security_group_id=18568811800631432&amp;p_fname=location.png"\</a>
{code}
if  I use query
{code}
select distinct
(case when (to_char(sl.ADDRESS1_LATITUDE) is null) and (to_char(sl.physical_address_latitude) is null) then null
else '<img src="#WORKSPACE_IMAGES#location.png"\image>'
end) MAP_link,
{code}
the column map_link is empty. I guess I do not know how to escape characters in javascript. Could you help me on this?
Thanks.
