Have you look at dynamic SQL:

 @sql varchar(1000)

@sql = 'CASE @MyParam '

@sql = @sql +  'WHEN 'A' THEN Select ID from MyTable '
@sql = @sql + '  WHEN 'B' THEN Select ID from MyTableTwo '
etc...

   exec (@sql)

 I can get a CASE statement to work in a query:

 Select ID
 FROM MyTable
 CASE  ID
  WHEN 2 THEN Order 1
  WHEN 3 THEN Order 2
 
 
 but not with a passed param:

 CASE @MyParam
  WHEN 'A' THEN Select ID from MyTable
  WHEN 'B' THEN Select ID from MyTableTwo
  WHEN 'C' THEN Select ID from MyTableThree

Is that possible.  All the examples I can find always have the CASE
statement as part of the query.
>From http://msdn2.microsoft.com/en-us/library/ms181765.aspx :

SELECT FirstName, Lastname, TelephoneNumber, 'When to Contact' = 
     CASE
          WHEN TelephoneSpecialInstructions IS NULL THEN 'Any time'
          ELSE TelephoneSpecialInstructions
     END
FROM Person.vAdditionalContactInfo


Thanks
