For SSRS in Visual Studio 2008, how can I make a variable accept multiple values as well as a single value?
===

I'm making a report with Visual Studio 2008, pulling the info from a table in a database. Let's say I just want to show the `Type` of employee (which is represented by an `int`, say 1-10) and their `Name`. Then my dataset would be this query:

    SELECT Type, Name
    FROM Employees
    WHERE Type = @Type

This is SSRS, so I do not need to declare or set the variable (correct me if I'm wrong). When I run the report, it will give me an option to type in an `int` for the `Type` and it will create the corresponding report. My question is how can I set it so that I can type `1,2,3` in for the `Type` so that I get a report with those types of employees? So having the `int` variable be able to accept a list of `ints` or just one `int`. Essentially the "resulting query" from that example would look like this:

    SELECT Type, Name
    FROM Employees
    WHERE Type = 1 AND Type = 2 AND Type = 3
