Title: How to do file design to work with Capesoft Replicate?
Post by: skyong38 on June 14, 2013, 04:30:08 AM

Hi,

The easiest way to implement parent-child for Nettalk is add an Auto-Increment Filed. It works fine.

Now, I want to extend it, to consolidate few database into one at HQ, so I choose Replicate. If Replicate, I need to add GUID + Auto-Increment Filed as unique, after this, can Nettalk still works?

Please advice.

Thank you.


Regards,
Nelson

Hi Nelson,

yes, Auto-Incrementing works, but it is a _lot_ better when designing your dictionary to use GUID fields as unique identifiers. Many problems that come later on, go away if you avoid auto-numbered fields as the primary key.

no, to make Replicate work all you need for the primary key is the guid. The auto-number does not need to be part of the key.

>> , after this, can Nettalk still works?

I'm certainly using NeTTalk with guids as the primary key, if that's what you are asking?

cheers

Hi Bruce,

Thanks for reply and clear my doubt. I thought NetTalk must use Auto-Increment, GUID also can.

Thank you very much. I know how to re-design my dct now.
