}Expand description
MERGE operator — match or create a node/pattern.
The processor first attempts to match a node with the given properties.
If found, applies ON MATCH SET operations. If not found, creates a
new node with the pattern properties and applies ON CREATE SET.
Fields§
§table_name: String§table_id: u64§properties: Vec<(String, Expression)>Properties from the MERGE pattern (name, expression pairs).
on_match: Vec<LogicalSet>SET operations to apply when the node already exists (matched).
on_create: Vec<LogicalSet>SET operations to apply when a new node is created.
