BI PUBLISHER : not able to select 'all' from the menu as parameter

Question

Hi ,
I have created a report using a SQL query . i created a list of values using the following sql query :
select     EDM_TRD_HDR.TRD_ID as TRD_ID
from     MUREXEDM.EDM_TRD_HDR
and selected this in the menu settings in parameters .
i checked on 'can select all ' option and also on 'NULL Values passed' button.
On clicking view , i am able to see the data for the default valu of the parameter. however, when i select 'all ' from the menu , i am just getting the column headings and no data .
please reply if you are aware of this problem.
Also let me know wether we can create a view selector for a BI publisher report and are there any functionalities which can be implemented in answers and not in the publisher.

Answer 1

You've selected 'null value passed' so you need to write the driving query in your data model in a way that will show all values when the parameter is null:
eg
select *
from
your_table
where
(:p_paramter is null or your_column = :p_parameter)
and ...
(assuming not multi select).
With view selector, you can create conditional regions so could mimic something like that. With regards to features they are completely different products - so almost everything.
