HelixDB Docs

Sometimes, you may want to set default values for item fields

N::NodeType {
  field1: String DEFAULT "default",
  field2: U32 DEFAULT 0,
  created_at: Date DEFAULT NOW
}

Helix will use the default value if a value is not provided when inserting the item.

Type	Example	Description
String	`DEFAULT "value"`	Default string literal
Number	`DEFAULT 0`	Default numeric value
Timestamp	`DEFAULT NOW`	Automatically set to current timestamp on creation

In the example below, the age field has not been provided when inserting the item so the default value of 0 will be used.

QUERY createUser(name: String) =>
    user <- AddN<User>({name}) 
    RETURN user
