Basic
Aliases
The output graph can rename fields in the output using aliases.
Aliases are useful when you want to apply two different filters to the same edge.
The example query that’s provided for you in the editor uses aliases to
include the friends
edge twice, with a unique set of arguments and fields
in each case.
Something to try: Query People
, then select and alias the xid
field as
username
and alias the query as users
. Then, query all people again, filtering
for just those with pets, and alias this query as peopleWithPets
. See if you
can combine these queries into a single operation.
