Simple object queries¶
Table of contents
Introduction¶
You can fetch a single node or multiple nodes of the same type using a simple object query.
Fetch list of objects¶
Example: Fetch a list of authors:
query {
authors {
id
name
}
}
query {
authors {
id
name
}
}
{
"data": {
"authors": [
{
"id": 1,
"name": "Justin"
},
{
"id": 2,
"name": "Beltran"
},
{
"id": 3,
"name": "Sidney"
},
{
"id": 4,
"name": "Anjela"
}
]
}
}
Fetch an object using its primary key¶
Example: Fetch an author using their primary key:
query {
authors_by_pk(id: 1) {
id
name
}
}
query {
authors_by_pk(id: 1) {
id
name
}
}
{
"data": {
"authors_by_pk": {
"id": 1,
"name": "Justin"
}
}
}
Fetch value from JSON/JSONB column at particular path¶
Example: Fetch the city and phone number of an author from their JSONB address column:
query {
authors_by_pk(id: 1) {
id
name
address
city: address(path: "$.city")
phone: address(path: "$.phone_numbers.[0]")
}
}
query {
authors_by_pk(id: 1) {
id
name
address
city: address(path: "$.city")
phone: address(path: "$.phone_numbers.[0]")
}
}
{
"data": {
"authors_by_pk": {
"id": 1,
"name": "Justin",
"address": {
"city": "Bengaluru",
"phone_numbers": [9090909090, 8080808080]
},
"city": "Bengaluru",
"phone": 9090909090
}
}
}
