Mapping a Single Report Param to 2 query params [message #846207]

Hi

My dataset is a subquery, accepting a single param called NumDays in two WHERE clauses. I need to map a single report parameter to these and cannot see how to get this to work without creating two separate report params. Any ideas anyone?

TIA

param_1 -> report_param1
param_2 -> report_param1

Not?

Hi,

Thanks - but that is what i tried already. I mapped two report params to the same query param thinking I'd get just one prompt at run time but it's not working that way.

Not sure if this what you are asking, but the only way to map one report
parameter to two data set parameters is to use property binding or
script to change the query. For example

define a data set with a query like select * from orderdetails

use a beforeOpen like
this.queryText = this.queryText + " where
ordernumber="+params["myparameter"].value;
