[Mondrian] Parameterized Mondrian Queries in PRD

[waw at 1783.com]

Thank you. That is what I needed! 

I have changed my query to:

WITH SET [selectedset] AS ${CSVClient}
select [selectedset] ON COLUMNS,
 {[Measures].[Count of Employees], [Measures].[Count of Declined], [Measures].[Count No Record], [Measures].[Count Requested But No Vaccination Record], [Measures].[Count Vaccinated], [Measures].[Count Vaccinated Elsewhere], [Measures].[% Vaccinated], [Measures].[% Declined], [Measures].[% No Record]} ON ROWS
from [Monthly Influenza Summary]
where ([Monthly Period].[${SelectedYear}])

I am using PRD parameters to get the set of customers in a multi-select, then I turn that set into a formatted array which I use in the query. The basics are there now. Now, I need to get PRD to create a dynamic set of columns for my report. I have seen someone using tables as a parameter, so I will get that part figured out.

String parameters are passed into Mondrian without any postprocessing by the reporting engine (if the parameter is a java.lang.String, otherwise we will throw a very visible exception). You are using a StrToMember which probably does not like the "{..}" syntax of the sets. Try a StrToSet instead, if you intend to pass a set. You can also skip the parameter function and use the classical ${...} parametrization syntax (PRD 3.6 or newer), which performs a simple replacement on the MDX string. To prevent code injections you can specify a subformat along with those parameters: ${param} will include the parameter without any modification. ${param,string} will quote the parameter value as MDX string (slap double quotes around it and escape all inner double quote chars) ${param,formattype,formatstyle} will treat the parameter as a message format request, so that you can format numbers, dates and so on properly. For the grammar of formattype and formatstyle have a look at http://download.oracle.com/docs/cd/E17476_01/javase/1.4.2/docs/api/java/text/MessageFormat.html On 20.07.10 15:18, waw at 1783.com wrote: > After looking through Julian's Jira note and looking through MDX notes a > bit more, I am wondering if the Parameter function is working in PRD.
