Query Layer with user-defined (dynamic) parameters in ArcGIS 10.1

I have prepared and published with ArcMap 10.1 to my ArcGIS Server a Query Layer to accesssome information in my database. My output map represents the EuropeanUnion states and using annotations, the number of cities and villages each country has.

Now, I would like to go a step further and try to specify some parametersin the WHERE clause of the SQL query that defines my query layer. Thereforethe user in my web application can select from a drop-down list box simple parameterslike filtering just by "Cities" or "Villages" or by population number.

I just would like to know if it is possible to configure ArcGIS to expectsome input parameters coming from the web and execute the SQL query with these parameters oncethey have been received. Is there a way of injecting those parameters backto the ArcGIS Server and make it calculate the data I need?

Please, could you provide any ideas or guidelines about how this would be done?
