AQL 如何返回整个文档而不是单项文档

Question

Below is the AQL Query.

for doc in `managed-function`
  collect mkey = doc.mkey
  return mkey

Above query returns only unique mkey list. I want the entire doc to be returned, how can I achieve it?

Answer 1

You need to add an INTO clause to the COLLECT operation, like this for example:

for doc in `managed-function`
  collect mkey = doc.mkey into docs = doc
  return {mkey, docs}
