Dissolve and its possibilities

[DavidMrázek]

Good day,
is it possible to use dissolve on a certain field but at the same time omit NULL concatenation in that field?

Thank you

David

If you query for the records that contain null in that field, then run the dissolve, it will be run only on the records that aren't null.  If you still need the records with null, save the results of the query to its own layer and merge it with the dissolve results
