SSRS - select where parameter and fixed value

So there is a lot of stuff about using SSRS parameters to select multiple values but nothing about using both a parameter and a fixed value using the in select statement. So what I'm trying to do is this: select * from table where id in (Parameter_1, 'total') Yet when I do that it complains its can't find 'Parameter_1'. I've gotten another report to work when its just: select * from table where id = Parameter_2 but this this isn't good enough in this use case.
