Updating a database from a JTable

Question

So, in my GUI class, the user searches for the records of an event and round, which returns 9 records into my JTable for me.
This is how i do thi
else { List<UpdateEventSetGet> searchResult = sql.searchRecords(sType, sType2); for(int x = 0, y = searchResult.size(); x < y; x++) { UpdateEventSetGet update = searchResult.get(x); model.setValueAt(update.getNationality(), x, 0); model.setValueAt(update.getFirstname(), x, 1); model.setValueAt(update.getLastname(), x, 2); model.setValueAt(update.getTime(), x, 3); } }
Now with user being able to see their search results in the JTable, they are able to edit it. Then once they click update, the new edited JTable should be updated into my database. Whats the best way to achieve this update? I was thinking about just taking the whole table model and sending that off to my database to replace what is there. But then what happens if they only change one word, is it a waste to change everything? Whats the best way to achieve this update?
Any Advise?

Sorry, when i say table i am making a bad reference to my table model, I meant the table model. What i am just trying to understand better is the actual update statement. So lets say the user updates one cell in the JTable, wouldnt the update need to be specific to that cell? So if you had a table model with four columns, Nationality, First_Name, Last_Name and Time_Set. This model also has 9 rows of data. Now i dont know what cells the user is going to update. So how is it possible to make an update statement for this?Well, come on. One of the columns is the table's primary key, right? So you don't let the user change that column. If they change any other column, you execute an update like
Update Table set Column5='Simple' where Column1='Key"{code}
Of course whichever column they update, you update the corresponding column in the database. You could make things more complicated, but why not just keep it simple?
