The download type can be timestamp, snapshot, or custom. You change the download type in the Table Mappings pane of the Mappings tab.
Timestamp-based download Choose this option to use timestamp-based download as the default. Only rows that have been changed since the last synchronization are downloaded. See Timestamp-based downloads.
Snapshot download Choose this option to use snapshot download as the default. All rows are downloaded even if they have not been changed since the last synchronization. See:
Custom download logic Choose this option if you want to write your own download_cursor and download_delete_cursor scripts instead of having them generated for you. See:
In Model mode, open the Mappings tab.
In the Table Mappings pane, select a remote table.
In the Download Type dropdown list, select Timestamp, Snapshot, or Custom.
If you chose Custom, open the Events tab:
Right-click the table and choose Go to Events.
Edit your download_cursor script and download_delete_cursor script with the appropriate business logic.
