Update data
A mutation can be turned into a update operation by starting the mutation
name with update.
A mutation will also be an update operation if it is annotated with @cql_update.
The mutation must take a single argument that is an input type for a mapped entity.
If successful, the mutation will return a Boolean value.
In order to execute the mutation, all primary key fields and at least one non-primary key
field must be input.
For example, the following mutation and associated query will update a single row:
-
graphQL command
-
Result of command
-
New record
type Mutation {
updateBook(book: BookInput): Boolean @cql_update
}
mutation updatePap {
updateBook(book: {
title: "Pride and Prejudice",
author: ["Jane Austen", "random other author"],
isbn: "978-0141439518" })
}{
"data": {
"updateBook": true
}
}{
"data": {
"bookByTitle": [
{
"title": "Pride and Prejudice",
"isbn": "978-0141439518",
"author": [
"Jane Austen",
"random other author"
]
}
]
}
}|
Updates are upserts. If the row doesn’t exist, it will be created. If it does exist, it will be updated with the new row data. |
