Disable a report link if no data found.

Question

I have a link from my portal report on a field. I want to disable the link if no data will be found. How do I do this.

Hey Rich,
Using Portal links are easy but at times they can be very limiting. You actually have to go one step backwards and create the link yourself in the SQL statement. You would call a function in the sql statement to produce the link.
SELECT
display_link_update(asset_seq) as Update_Record,
column2,
column3,
from table
display_link_update is the function call and I'm passing one variable, asset_seq. Now the function can do the link creation.
CREATE OR REPLACE FUNCTION "PROPERTY"."DISPLAY_LINK_UPDATE"
(asset_seq1 in varchar2) return varchar2 is tag varchar2(4000);
begin
if asset_seq1 is not null
tag:='Update Link';
else
tag:='Update Link'
return tag;
end;
I hope this helps.
