Query Has No Return

Erroneous Code Example

This warning occurs when a query does not have a RETURN statement. While not always an error, queries typically should return a value.

QUERY getUser(id: ID) =>
    user <- N<User>(id)

N::User {
    name: String,
}

Solution

Add a RETURN statement to specify what the query should return, or use a mutation operation like INSERT, UPDATE, or DROP if the query is intended to modify data without returning a value.

QUERY getUser(id: ID) =>
    user <- N<User>(id)
    RETURN user

N::User {
    name: String,
}
