Preparedstatement - please test this code!!

Question

I hope someone can test this code and tell me if it works. It seems to work on my computers (win98 and win2000, and access 2002 database, compiling etc,and even returns that it updated 1 record. But the database is unchanged. Commit is default to autocommit, what else could be causing this? None of the setxxx commands work. Yet no errors are given. Please test and let me know. Or, send me similar simple code that works on an access 2002 database from win98 or 2000. I am wondering if access 2002 has something to do with this. I am using default ODBC driver that came with the OS.
Thank you,
Jacques

stmt.setString( 1, "John" );
stmt.setInt( 2, 2);
System.out.println("about to update");
int count = stmt.executeUpdate();
System.out.println("number updated=" + count);
catch( Exception e ){
System.out.println("Error:" + e);
Database: Set up access database with table employee at least 2 records, one field called emp_id, register it in odbc as dbtest

Answer 1

Ok, for anyone else that encounters this, I found the answer! After a week of very frustrating testing, I stuck in a close() to the connection, and the changes were then actually made. I had counted on Java to close them properly upon exit, but I must specify the conn.close() after the executeUpdate before they take effect. Another weird worm of Java IMHO.
