From Class Model:
public TableModel getTableData() {
TableModel model=null;
try {
String sql = "SELECT eventID as 'Event ID', date as 'Date',eventName as 'Name', time as 'Start Time' FROM Event";
pst = conn.prepareStatement(sql);
rs = pst.executeQuery();
model = (DbUtils.resultSetToTableModel(rs));
}
catch(SQLException e){
e.printStackTrace();
}
finally {
try {rs.close(); pst.close(); }
catch(SQLException e){} }
return model;
}
public void getEvent(String tableClick) {
Events e = new Events();
try {
pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
rs = pst.executeQuery();
while(rs.next()){
e.setEventName(rs.getString(2));
e.setEventDate(rs.getDate(3));
e.setEventTime(rs.getString(4));
e.setEventVenue(rs.getString(5));
e.setEventDetail(rs.getString(6));
e.setEventOpportunity(rs.getString(7));
e.setEventMoreDetails(rs.getString(8));
e.setEndTime(rs.getString(9));
}
}
catch(SQLException ex){
ex.printStackTrace();
} finally {
try {
rs.close();pst.close();conn.close();}
catch (Exception ex){}
}
} //end getEvent
From Class Controller:
@Override
public void valueChanged(ListSelectionEvent event) {
int rowSelected = view.tableEvent.getSelectedRow();
String tableClick = view.tableEvent.getModel().getValueAt(view.tableEvent.convertRowIndexToModel(rowSelected), 0).toString();
model.getEvent(tableClick); //tell model to change its state based on user input on views - model is instance of class model
}
When I run my program I have stacktrace showing error at line pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
of the Model Class, and line model.getEvent(tableClick);
of the Controller class. Having run the programme with break points in debug mode in NetbeanIDE, I can see only the e.setEventName(...)
being populated with a value from database, while all other values of the Event
bean class are null. e.setEventDate(...)
sets date as #2222. If you need further information I will edit my post. but this is really bugging me.
Is it the ListSelectionListener causing problem, perhaps mouseListener
more appropriate?
to further add, if I change the getEvent()
to
public void getEvent(String tableClick) {
Events e = new Events();
try {
pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
rs = pst.executeQuery();
while(rs.next()){
JOptionPane.showMessageDialog(null, "Yess");
}
}
it only executed displays Yes
the first time a row is clicked. Not on the second click on another row.
