Database NULL values

Hi

I have a Date attribute which is sometimes missing. In that case, I use the value "NULL" when I create the field ("Generate Attributes"). In the database, I end up with the value "1970-01-01" instead of NULL. What should I do to have actual NULL values in the database?

TIA

Hi,

I don't know your process setup and what exactly you do, but RapidMiner uses NaN for missing values. That should lead to null values in your database if you use the Write Database operator.

Regards,
Marco
