Question

There’s a stored procedure I’m studying. Would this be a possible call? –

exec [dbo].[prc_RPT_Respondent_Answer] '20121011', '20121017' , 18964 , "3", "30,31,32,33,34,35,36,37,38,39,130"

I’m guessing the "30,31,32,33,34,35,36,37,38,39,130" argument is handled by code like the following(which is from the referenced sproc:

BEGIN
    INSERT 
    INTO #tempClientLK_ResponseStatuses
    SELECT CONVERT(INT, val) FROM dbo.Split(@ClientResponseRange, ',')  
END

Answer 1

Yes, this should work. I already have used this approach, few times.
If you are asking about how to write that table valued function dbo.Split() then you may check this link-
