Personally I tend to do this kind of stuff by passing the parameter as xml. In 
your SQL you can then join to the xml as though it were a table.

Subject: RE: SQL CLR table as function parameter


Oh oh! http://msdn.microsoft.com/en-us/library/ms131103.aspx has some bad news:
 
Table-valued parameters are user-defined table types that are passed into a 
procedure or function and provide an efficient way to pass multiple rows of 
data 
to the server. Table-valued parameters provide similar functionality to 
parameter arrays, but offer greater flexibility and closer integration with 
Transact-SQL. They also provide the potential for better performance. 
Table-valued parameters also help reduce the number of round trips to the 
server. Instead of sending multiple requests to the server, such as with a list 
of scalar parameters, data can be sent to the server as a table-valued 
parameter. A user-defined table type cannot be passed as a table-valued 
parameter to, or be returned from, a managed stored procedure or function 
executing in the SQL Server process.
 
So I have to find some other convenient way of getting variable numbers of 
parameters into a managed function.
 
Is there a T-SQL equivalent of String.Join(...) that easily joins many strings 
together with a separator, I could possibly accept that a proxy variable length 
parameter.
