Could you write a special stored procedure for me in SQL 2005?

[mycwcgr]

When I execute the SQL "select TagName from Th_TagTable where IDTopic=@IDTopic" , it return several rows such as
TagName= http://www.hothelpdesk.com
TagName= http://www.hellocw.com
TagName= http://www.supercoolbookmark.com



I hope there is a stored procedure which can join all TagName into a single string and return,
it means when I pass @IDTopic to the stored procedure, it return "http://www.hothelpdesk.com, http://www.hellocw.com, http://www.supercoolbookmark.com"

How can write the stored procedure?
