🔍 Code Extractor

Retrieves a single dbo_InterventionProtocolFlocks node from a Neo4j graph database by its unique ID.

Purpose

This function queries a Neo4j database to fetch a specific intervention protocol flocks record identified by its ID. It's designed for retrieving individual records from the dbo_InterventionProtocolFlocks node collection, typically used in applications managing intervention protocols for livestock flocks or similar agricultural/veterinary systems.

Source Code

def get_dbo_interventionprotocolflocks_by_id(id):
    """Get a dbo_InterventionProtocolFlocks node by its ID"""
    query = """
    MATCH (n:dbo_InterventionProtocolFlocks {id: $id})
    RETURN n
    """
    result = run_query(query, {"id": id})
    return result[0] if result else None

Parameters

Parameter Details

id: The unique identifier of the dbo_InterventionProtocolFlocks node to retrieve. Expected to be a string or integer that matches the 'id' property of nodes in the Neo4j database. This parameter is used in a parameterized query to prevent injection attacks.

Return Value

Returns the first matching dbo_InterventionProtocolFlocks node as a dictionary-like object if found, or None if no node with the specified ID exists. The returned object contains all properties of the matched node from the Neo4j database.

Dependencies

• neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

# Assuming run_query is already defined and configured
# Example 1: Retrieve a node by ID
node = get_dbo_interventionprotocolflocks_by_id(12345)
if node:
    print(f"Found node: {node}")
else:
    print("Node not found")

# Example 2: Using with string ID
node = get_dbo_interventionprotocolflocks_by_id("protocol-001")
if node:
    # Access node properties
    node_data = node['n']
    print(f"Protocol details: {node_data}")

Best Practices

• Ensure the run_query function is properly implemented with error handling and connection management
• Validate the ID parameter before calling this function to ensure it matches expected format
• Handle the None return value appropriately when the node is not found
• Consider implementing caching if this function is called frequently with the same IDs
• Use parameterized queries (as done here with $id) to prevent Cypher injection attacks
• Ensure proper Neo4j database indexes exist on the 'id' property for optimal query performance
