Unable to pass report column value to url in select statement. Please help

Question

Hi all,
I am trying to pass the report column value as follows:
select key, num,
case when Attachmentcnt(KEY) != 0 then
'f?p=&APP_ID.:91:&SESSION.:'' '':NO::P91_KEY,P91NUM,P91_PREVPG:'And I am passing values as follows:
{noformat}
'#KEY#,'#NUM#','9' ELSE null
END Attachment
from tableA
{noformat}
But, I am not able to figure out correct sysntax to pass these column values. Can anyone give me some help. I appreciate it.
rgds,
Suma.

Answer 1

Suma,
If you're trying to generate a column with a URL, try something like the following:
select key, num,
case when Attachmentcnt(KEY) != 0 then
'f?p=&APP_ID.:91:&SESSION.:'' '':NO::P91_KEY,P91NUM,P91_PREVPG:'
|| tableA.key || ',' || tableA.num || ',' || :P91_PREVPG
else NULL
end
FROM tableA;
But the best way to pass these would include checksum values against the values of your parameters (to make sure a user doesn't hack them). You'll need to check the Apex User manual for details - See "Understanding Session State Protection".
Good luck,
