We upload all of our parts catalog every day into the datastore using bulkloader and an input csv file generated from a MySQL database.
We have some properties on the parts catalog kind in the datastore that are not in the csv. We want to be able to find all of the entities using GQL that don't have the properties yet that are only in the datastore version of the entities (not the MySQL database). GQL doesn't let you query for entities that don't have a property, only properties that are NULL, for example. How can we find the entities, in an efficient way, that don't yet have the additional properties? If we change our bulkloader to send the properties (using a custom post_import_function to add the properties) then we will overwrite the existing properties in the datastore (which we don't want to do!). Please help with solutions to this issue. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
