function get_parameter_medicationtypeproperties_by_id

Maturity: 42

Retrieves a Parameter_MedicationTypeProperties node from a Neo4j graph database by its unique identifier.

Purpose

This function queries a Neo4j database to fetch a specific Parameter_MedicationTypeProperties node using its ID. It's designed for retrieving medication type property parameters stored in a graph database, typically used in healthcare or pharmaceutical applications where medication properties need to be accessed individually.

Source Code

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

Parameters

Name Type Default Kind
id - - positional_or_keyword

Parameter Details

id: The unique identifier of the Parameter_MedicationTypeProperties node to retrieve. Expected to be a string or integer that matches the 'id' property of nodes in the Neo4j database. This should correspond to an existing node ID in the database.

Return Value

Returns the first Parameter_MedicationTypeProperties node that matches the given ID as a dictionary-like object containing all node properties, or None if no matching node is found. The return type is either a Neo4j node record (typically accessed as a dictionary) or None.

Dependencies

  • neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

# Assuming run_query function is defined and Neo4j is configured
from neo4j import GraphDatabase

# Define run_query helper function (example implementation)
def run_query(query, parameters=None):
    driver = GraphDatabase.driver('bolt://localhost:7687', auth=('neo4j', 'password'))
    with driver.session() as session:
        result = session.run(query, parameters)
        return [record['n'] for record in result]
    driver.close()

# Use the function to retrieve a medication type properties node
medication_props = get_parameter_medicationtypeproperties_by_id('med_type_001')

if medication_props:
    print(f"Found medication properties: {medication_props}")
else:
    print("No medication properties found with that ID")

Best Practices

  • Ensure the run_query function is properly implemented with error handling and connection management
  • Validate the ID parameter before passing it to prevent injection attacks or invalid queries
  • Consider adding error handling for database connection failures
  • The function assumes run_query returns a list; ensure this contract is maintained
  • Consider adding type hints for better code documentation (e.g., def get_parameter_medicationtypeproperties_by_id(id: str) -> Optional[Dict])
  • Close Neo4j driver connections properly to avoid resource leaks
  • Consider caching frequently accessed nodes to reduce database load
  • Add logging for debugging and monitoring database queries
