I set the id as primary key and also auto increment. But if i enter the same data, it will be interpretted as a different data because of the different id from the auto increment. How do i prevent it from re-entering the same data?
I set another attribute in the table as unique. So that prevents me from reentering redundant data. Duplicate entry '224924' for key 2.
I am retrieving an xml data from spongecell and updating my database accordingly. So how can i only update the changes from the calendar events that i have set?
