Error when update: Optional feature not implemented

Question

Hi, all,
I got the exception: "[Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented" when I use MS Access to update my record.
I searched the forum, but i couldn't get my answer. I can do select and insert into this table. but i couldn't update it. I am using jdbc-odbc driver. Thanks.
The code I am using:
int date = 186;
String id = "BUF";
String max = id + "_MX";
//String min = id + "_MN";
//String prec = id + "_P";
query = "update " + tableName + " set " + max + "=? where date=?";
try {
ps = con.prepareStatement(query);
ps.clearParameters();
ps.setFloat(1, getMax());
// ps.setFloat(2, getMin());
// ps.setFloat(3, getPrecip());
ps.setInt(2, date);
result = ps.executeUpdate();
ps.close();
} catch (SQLException e) {
System.out.println("Database error, " + e.getMessage());

Thanks everybody! The problem was solved. I should use setDouble() other than setFloat() method.
