SQL Union query with itself with multiple sets of variables

Zone: SQL Server 2005

Tags: Microsoft, SQL Server, 2005, T-SQL

Hello Experts,

I have a statement that has a set of variables in the WHERE clause. Those variables are set in SQL Reporting by the user running the report. I'd like to put all of the results together in one query, but I don't want to UNION the same query 10 times with the different sets of variables to get what I want.
Is there an easy way to have the ONE query that UNIONS itself over and over until I'm done with my list of variables. ... almost like a For-Next / Do-Loop Until statement. I've never done this before in SQL.

Thanks

         
             where (c.accrual_plan_key = @accrual_plan_key and d.active = @active and b.project_key = @project_key and b.task_key = @task_key and b.work_date >= '8/1/2007' and b.work_date <= @report_date)
			group by a.person_key, b.project_key, b.task_key, c.end_date
			) 
			V1 on V1.person_key = a.person_key
where (e.chain_key = @chain_key and c.accrual_plan = @plan and b.active = @active and d.exempt_status = 'E' and a.posted_timestamp <= (@report_date + 4)  and d.end_date = '12/31/2099')
