SQL Server stored procedure parameters

Question

I am developing a framework, where in I am a calling stored procedure with dynamically created parameters. I am building parameter collection at the runtime.

I'm going on a bit of an assumption here, but I'm assuming the logic inside the procedure gets split up via task. And you cant have nullable parameters as @Yuck suggested because of the dynamics of the parameters?

So going by my assumption

If TaskName = "Path1" Then Something

If TaskName = "Path2" Then Something Else

My initial thought is, if you have separate functions with business-logic you need to create, and you can determine that you have say 5-10 different scenarios, rather write individual stored procedures as needed, instead of trying one huge one solution fits all approach. Might get a bit messy to maintain.

But if you must...

Why not try dynamic SQL, as suggested by @E.J Brennan (Forgive me, i haven't touched SQL in a while so my syntax might be rusty) That being said i don't know if its the best approach, but could this could possibly meet your needs?

CREATE PROCEDURE GetTaskEvents
    @TaskName varchar(50)
    @Values varchar(200)
AS
BEGIN
  DECLARE @SQL VARCHAR(MAX)

  IF @TaskName = 'Something'
  BEGIN
    @SQL = 'INSERT INTO.....' + CHAR(13)
    @SQL += @Values + CHAR(13) 
  END

  IF @TaskName = 'Something Else'
  BEGIN
    @SQL = 'DELETE SOMETHING WHERE' + CHAR(13)
    @SQL += @Values + CHAR(13) 
  END

  PRINT(@SQL)
  EXEC(@SQL)    
END

(The CHAR(13) adds a new line.. an old habbit i picked up somewhere, used to help debugging/reading dynamic procedures when running SQL profiler.)
