I have a question on loading data from an IXF file into a DB table(s).
The IXF is a backup from one DB and contains several years worth of data from a source. I want to load only the "new" records to the target, ones where a primary key does not previously exist. The key includes month and year. This will be a repeatable process every month.
Example: I get a monthly dump of data that contains all months data for the current a year. Every month I want to only append the new records to the target DB/Tables and not replace any previously existing records.
What would be the most efficient design/process to do this? APPEND?
Thanks in advance
