I have written the following code for getting a day, month year and time from a form and inserting this into a table in Access, but always get the
errorjava.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]Datetime field overflow (null)
Also how would I get this code to update a table which already has the date and time inserted into it?
Thanks for your help, this is really cracking me up and am going to throw the computer out the window soon!!!

The code is as follows:
<!--bookAppoints.jsp-->
<%--set the content type, import the java.sql classes, include a file containing a page heading--%>
<%@page contentType="text/html"%>
<%@page import="java.sql.*"%>
<%@page import="java.text.*"%>
<%@page import="java.util.Calendar"%>
<%@page import="java.lang.String"%>
<%--start the html--%>
<html>
<body>
<CENTER><H3>Book an appointment H3></CENTER>
<%--set up variables for the sql statement, the connection to the database,
and the results --%>
<%
String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
String connectionURL = "jdbc dbc:Vet";
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
PreparedStatement ps = null;
int day= 0;
int month = 0;
int year = 0;
int hour = 0;
int mins = 0;
//Calendar c= new Calendar();
Calendar c = Calendar.getInstance();
c.set(year, month, day, hour, mins);
Date appoint_Date = new Date(c.getTime().getTime());
Time appoint_Time = new Time(c.getTime().getTime());
//make the database connection
try{
Class.forName(driverName).newInstance();
con = DriverManager.getConnection(connectionURL);
ps = con.prepareStatement("INSERT INTO appoints1 (appoint_Date, appoint_Time) values (?,?)");
ps.setDate(1, appoint_Date);
ps.setTime(2, appoint_Time);
ps.execute();
if (ps != null) {
ps.close();
}
}
catch (Exception e){
%><%= e %>
<%
}
//print out the results

//close the database
try{
if (con != null) {
con.close();
}
}
catch(Exception e) {%>
<%= e %>
<%
}
%>
<%--close the html --%>
</body>
</html>

Are you setting year, month, day, etc to anything before putting the value in the database? If everything is set to zero, that would be dawn of time. Some databases may not be able to handle that value.
 
It is sorta covered in the JavaRanch Style Guide.
