SQL Server で INSERT コマンドの後に挿入された ID を取得する方法は?

<code class="language-csharp">public class MemberBasicData
{
    public int Id { get; set; }
    public string Mem_NA { get; set; }
    public string Mem_Occ { get; set; }     
}

public int CreateNewMember(string Mem_NA, string Mem_Occ)
{
    using (SqlConnection con = new SqlConnection(Config.ConnectionString))
    {
        using (SqlCommand cmd = new SqlCommand("INSERT INTO Mem_Basic (Mem_Na, Mem_Occ) OUTPUT INSERTED.ID VALUES (@na, @occ)", con))
        {
            cmd.Parameters.AddWithValue("@na", Mem_NA);
            cmd.Parameters.AddWithValue("@occ", Mem_Occ);
            con.Open();
            int newId = (int)cmd.ExecuteScalar();
            con.Close();
            return newId;
        }
    }
}</code>

<code class="language-csharp">public int CreateNewMember(string Mem_NA, string Mem_Occ)
{
    using (SqlConnection con = new SqlConnection(Config.ConnectionString))
    {
        using (SqlCommand cmd = new SqlCommand("INSERT INTO Mem_Basic (Mem_Na, Mem_Occ) VALUES (@na, @occ); SELECT SCOPE_IDENTITY();", con))
        {
            cmd.Parameters.AddWithValue("@na", Mem_NA);
            cmd.Parameters.AddWithValue("@occ", Mem_Occ);
            con.Open();
            int newId = Convert.ToInt32(cmd.ExecuteScalar());
            con.Close();
            return newId;
        }
    }
}</code>
