SSRS - select where parameter and fixed value

Question

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.

Answer 1

Ok the problem was actually with the parameter itself.

I had to create a new one in the query called @Parameter_1 and then set it up in the query parameter tab and delete the old one.

Really confusing.
