Thanks Bryan Good advice......................
I have successfully run the program excluding any ref to the TRADES table - all OK so it is in the Trades Table code where I am going wrong...... As I use same code with the other table = it seems perplexing using a debugger - I would love to but as I need to load a strategy onto the Dukascopy platform and then run it - I do not understand how to include a debugger in the loop but I do have Netbeans IDE and can load my program into it (of course) I keep feeling that there is something I am not understanding about updating two different tables in the same dbase Regards Bob M -- View this message in context: http://apache-database.10148.n7.nabble.com/Updating-2-derby-tables-tp147386p147419.html Sent from the Apache Derby Users mailing list archive at Nabble.com.
