Part of the subscription materialization process involves unloading subscription data from the primary table so it can be loaded into the replicate table. Subscription data is the data in the primary table that is requested by the subscription.
Data unloading utilities are usually provided with data server software. You can use one of the OEM-supplied data unloading utilities or a database unload utility of your choice.
Once subscription data is unloaded from a primary database,
you may need to perform datatype translation on the unloaded data
before loading the data into the replicate database. See “Datatype translation issues.”
