Replace Parameter Doesnt Work

I have the following in my commandtext but it doesnt seem to replace the LanguageColumnName variable:


       Dim cmd As New SqlCommand("SELECT '+@LanguageColumnName+' FROM tblSports a INNER JOIN tblUsersAndSports b ON a.SportID=b.SportID " & _
        "WHERE b.UserCode=@UserCode", MyConnection)
        cmd.Parameters.Add(New SqlParameter("@UserCode", UserCode))
        cmd.Parameters.Add(New SqlParameter("@LanguageColumnName", LanguageColumnName))

I have tried '+@LanguageColumnName+' and also just @LanguageColumnName but this variable isnt replaced for some reason.

The value of LanguageColumnName is "de"...the funny thing is that when I just type my command like the following it DOES work..:

SELECT de FROM tblSports a INNER JOIN tblUsersAndSports b ON a.SportID=b.SportID " & _
        "WHERE b.UserCode=@UserCode

What am I doing wrong?
