Importing New Records Only

[04evildave]

Is it possible to import only new records?

That is, can FM recognise a matching record, and then ignore it completely, (only importing unrecognised records)?

Currently, my belief is that if I use 'matching records' in the import, then FM will update the results (which I don't want)?

Please help if you know something I don't :qwery:

No - but this is pretty fast, well he's looping but it should be posible with a scripted replace as well:

But then you have to deal with deleting the duplicates. This could be a slow process on some imports, where a large portion are duplicates.

In my opinion, it's better to reduce the source set of data prior to importing, so any existing records are not part of the import. This could be done by relating between the source and destination table (by whatever defines a duplicate,) and then in the source table, finding and omitting those those that have a related destination record. You would need to use a FileMaker file to hold the source import data in this intermediate step (since you can't relate directly to an Excel file or something.)

Another option: If you track creation dates in your source data, you could reduce the import source data to only include those created since the last import.
