I've got a stored procedure in my database, that looks like this

```
ALTER PROCEDURE [dbo].[GetCountingAnalysisResults] 
    @RespondentFilters varchar
AS
BEGIN

@RespondentFilters = '''8ec94bed-fed6-4627-8d45-21619331d82a, 114c61f2-8935-4755-b4e9-4a598a51cc7f'''

DECLARE @SQL nvarchar(600)

SET @SQL = 
   'SELECT *
    FROM Answer
    WHERE Answer.RespondentId IN ('+@RespondentFilters+'''))
    GROUP BY ChosenOptionId'

exec sp_executesql @SQL

END

```

It compiles and executes, but somehow it doesn't give me good results, just like the IN statement wasn't working. Please, if anybody know the solution to this problem, help me.
