Getting started with G.apex

Default Value

We can specify the default values in G.apex query.

{
    "query": {
        "book": {
            "@id": "2",
            "name": "",
            "author": {
                 "name": "Unknown author"
             }
        }
    }
}

Here if the author of the book is not found, Unknown author will be returned as the default value.
