Passing parameters in the f?p URL

Question

Hi,
I am trying to add a link from a Bar Chart to a
report such that information from the chart
"context" can be passed to the report page.
(Following the "Create a drill down pie chart" How-to)
The sql for the bar chart is like this:
select
'f?p='
||:APP_ID || ':3:' || :APP_SESSION || ':::'
||:P1_SHOW,P_YEAR,P_B:'
||:P1_SHOW,my_t.year,my_t.b link,
a label,
b value
from
select a, b, year
from MY_TABLE my_t
where lower(a) = lower(:P1_SHOW)
where :P1_SHOW is a selection list.
The problem is that the application builder errors with
'ORA-00904: "MY_T"."YEAR": invalid identifier'.
If I have only a single item name and a single item value
(eg. omit the P_YEAR and P_B names and values) then
all is well. The target page 3 can be linked to but the
report is hard wired with "good" values for B and YEAR.
I am using the 1.6 verion of html db.
All and any help would be appreciated thanks = )

Sinclair,
The syntax for passing multiple items through the URL is as follows:
P1_ITEM1,P1_ITEM_2:value1,value2Thus, you need to make some changes to your SQL in order for it render your link & parse correctly:
select
'f?p='
|| :APP_ID || ':3:' || :APP_SESSION || '::::P1_SHOW,P_YEAR,P_B:'
|| :P1_SHOW || ',' || my_t.year || ',' || my_t.b link,
a label,
b value
from
select a, b, year
from MY_TABLE my_t
where lower(a) = lower(:P1_SHOW)
)(I haven't tested the above code, but with some luck, it should work.)
Thanks,
