Example

<%
    Dim conn, rs
    Set conn = Server.CreateObject("ADODB.Connection")
    conn.Open "Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=MyDatabase;User ID=myUser;Password=myPassword;"

    Set rs = Server.CreateObject("ADODB.Recordset")
    rs.Open "Employees", conn, 1, 3

    rs.Filter = "EmployeeName='Jane Doe'"
    rs("Department") = "Finance"
    rs.Update

    Response.Write("Record updated successfully.")

    rs.Close
    conn.Close
    Set rs = Nothing
    Set conn = Nothing
%>

Explanation: This example demonstrates updating the department of an employee named Jane Doe using the Filter and Update methods.
