Avoid conditionally suprressed sub report to fetch data from DB.

Question

Do we have any option in crystal designer to avoid a suppressed subreport to fetch data from DB?
I have two sub reports in Report Footers say 'a' and 'b'.Report footer sections have a suppression formula based on parameter input.
Hence based on the parameter input only one sub report will get printeded.However I noticed that only one sub report is getting printed but both sub reports are fetching the data from DB.
I have also tried putting the suppression formula in suppress formula field of Sub report using format sub report option but it did not help.
Any idea how can we avoid a subreport that is suppressed to fetch data from DB.

Hi,
Suppress can only suppress the data, it cannot stop the query attached being running from the database, One thing you can do  only if your input parameter is a DB level parameter is you can have a case statement in the where clause of your query to avoid reading the records there by increasing the performance of the query.
Say, your parameter value 1 specifies that you want to suppress the report and in other words, you dont want to read the records from the DB.
Select feild1, field2,....from Table1
where 1 = case when @param = 1 then 0 else 1 end
Hope this helps,
Thanks
