Query problem in non US locale and Buddhist Era

Question

I try to query a table with a sql statement. Then I use the result from previous statement to query again. But there's no result from the second statement??
I think it's problem with Regional Options in the machine.
I'm using w2k sp4.
JDK1.5
MySQL 4.0.18
MySQL connector 3.1.6
Locale Thai, Default Lang Thai
Here is the code
PreparedStatement ps = cn.prepareStatement("select * from EBMS_FRAUD_ATTEMPTS order by action_date asc");
date1 = rs.getDate("action_date");
cardNo1 = rs.getString("user_card_number");
action1 = rs.getString("action");
System.out.println("date1 : " + date1);
System.out.println("cardNo1 : " + cardNo1);
System.out.println("action1 : " + action1);
ps = cn.prepareStatement("select * from EBMS_FRAUD_ATTEMPTS where action_date=? and user_card_number=? and action=? order by action_date asc");
ps.setDate(1, new java.sql.Date(date1.getTime()));
ps.setString(2, cardNo1);
ps.setString(3, action1);
System.out.println("date2 : " + date2);
System.out.println("cardNo2 : " + rs.getString("user_card_number"));
System.out.println("action2 : " + rs.getString("action"));from the testing, there's no result from the 2nd statement.
Here is output from 1st statement.
date1 : 2005-03-04
cardNo1 : 1234123412341234
action1 : test1The solution can be
1. change the locale in regional options to en/US. or.
2. manually convert date in Java code using the method below before setDate parameter in the 2nd statement.
     private Date convtDate(Date dInput) {
          SimpleDateFormat dfUS = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss", Locale.US);
          SimpleDateFormat dfTH = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss", new Locale("th", "TH"));
          try {
               return dfTH.parse(dfUS.format(dInput));
          } catch (ParseException e) {
               return null;
ps = cn.prepareStatement("select * from EBMS_FRAUD_ATTEMPTS where action_date=? and user_card_number=? and action=? order by action_date asc");
ps.setMaxRows(1);
ps.setDate(1, new java.sql.Date(convtDate(date1).getTime()));
ps.setString(2, cardNo1);
ps.setString(3, action1);
...Both solutions are not good at all. The 1st solution break the run anywhere concept. The 2nd solution is hardcoding. I think there should be a better solution.

Answer 1

So you think that is the problem? I would suggest you change "think" to "know" there before proceeding. If your solution #2 actually works (you didn't say that) then the locale most likely is the problem. In that case you should contact the maker of your JDBC driver and report the bug.
