No.... I don't want to drop it ... there is valuable data in there! I only want to create it if it doesn't already exist... likely going to happen first time the application will run. I want to create the table then and populate. But not the next time.
Should I just let Java throw and exception and catch it ? Write a function for this would be optimal, although I have no idea what the correct syntax is.
Cheers, Jen

Probably better to do:
DROP TABLE IF EXISTS post_codes;
CREATE TABLE post_codes(...);
