I have a report where the WHERE clause is determined by a parameter @param.
SELECT SOMESTUFF
FROM SOMETABLE
WHERE thing = @param
I've added values to the parameter so at runtime, the user decides what to run the report for from a drop down box. I want to make an option to run it for all the values I defined as well. I haven't been able to figure out the code to make this happen.
So if I've given values A, B, C
to the parameter, how do I tell it to do all of them in the expression?
