Dgraph GraphQL Tour
Basic
Sort Query Results
You can sort (or order) query results by using the order
argument on edges and
query<Type>
query functions.
When you apply ordering, the visualization of the graph remains unchanged, but the JSON response returned contains an ordered list.
The generated <type>Order
input type accepts three arguments:
asc
- Sort by a field in ascending orderdesc
- Sort by a field in descending order, andthen
- Add an additional sort argument.
In the example query shown in the editor, we query all nodes of
the type Person
and sort those nodes by the name
field in ascending order.
Something to try: Sort Alice’s friends by their age, in descending order; and then by their name, in ascending order.
For every type, Dgraph will generate a list of fields that are orderable. Edges to other nodes are not orderable fields within a type.
To introspect the available order fields, inspect the generated
<type>Orderable
enum
.
{
__type(name: "PersonOrderable") {
name
enumValues {
name
}
}
}
