HelixQL is deprecated in HelixDB v2. Queries are now written with the Rust DSL and dispatched as JSON — see the Querying guide. This section is kept as a reference for legacy HelixQL projects.

V   Vector

Select vectors from your graph to begin traversal. 
V<Type>(vector_id)

​
Example 1: Selecting a vector by ID

QUERY GetDocumentVector (vector_id: ID) =>
    doc_vector <- V<Document>(vector_id)
    RETURN doc_vector

QUERY CreateDocumentVector (vector: [F64], content: String) =>
    doc_vector <- AddV<Document>(vector, {
        content: content
    })
    RETURN doc_vector

from helix.client import Client

client = Client(local=True, port=6969)

vector_payload = [0.12, 0.34, 0.56, 0.78]

created = client.query("CreateDocumentVector", {
    "vector": vector_payload,
    "content": "Chunk about vector queries.",
})
vector_id = created[0]["doc_vector"]["id"]

result = client.query("GetDocumentVector", {"vector_id": vector_id})
print(result)
