How to determine different errors during update database with JDBC 2.0

Question

During updating my database (MS Access 2000) using JDBC 2.0, I entered a value for the primary key field which has existed
in the database. However, when executing the method "udpateRow()" it gives me an error message "Error in row" and the
database was not updated.
When I update an Integer field with a non-integer value (e.g: Characters ), it also gives me the same error message. When I
update a Date field with a non-date value, it still displays the same error message.
How can I determine for each of the cases from the SQLException thrown that the actual error has occurred since I want to
display a different customized message indicating the different errors that occurred during updating??
Currently, part of my code is as follows:
          int currentRow = rs.getRow();
          String values[] = new String[ rsmd.getColumnCount() ];
          // Initialize values[] begins here:
          for( int count = 1; count <= rsmd.getColumnCount(); count++ ) {
               rs.updateObject( count, values[ count - 1 ] );
          try{
               rs.updateRow();
          catch( SQLException e ) {
               System.out.println( e.getMessage() );
               rs.cancelRowUpdates();
               rs.absolute( currentRow );
Can someone please help me solve this problem?? THANKS.. :)

Rather than attempting to figure out which column value causes the update to fail, I would try validating the input data before you attempt to use it in a SQL update. Of course, this would only be useful if you know what data types the inputs are supposed to be in advance of running the update.
