Response.Redirect variable depending on a SQL result. How to ?

Hello,

I have code below

SQL is ok and results as I need

Problem is add result just into Response.Redirect

I tried to put directly from sql, put result into a variable like below and use the variable

But it is not working as expect

Any idea ?

Code:
<%
set rs=conn.execute("select url from encurta where id="&request.querystring("id")&"")
encurta=rs("url")
Response.Redirect "encurta"
%>
