Delivery template Vs delivery

Hi Team,

If we create a workflow view folder, We are able to see all workflows from our environment. Because this workflows are stored in xtl:workflow schema.

But delivery template and delivery are stored in same schema nms:delivery. But how it gets differentiated as delivery or delivery template?

Or, if i need to query all deliveries (and not delivery template) or only delivery template (and not deliveries), how can i query it in nms:delivery schema?

Thanks and regards,

ParthaSarathy.
