python javascript rust java shell

from falkordb import FalkorDB
client = FalkorDB()
result = client.drop_constraint('g', 'UNIQUE', 'NODE', 'Person', ['first_name', 'last_name'])
print(result)

import { FalkorDB } from 'falkordb';
const client = await FalkorDB.connect();
const result = await client.dropConstraint('g', 'UNIQUE', 'NODE', 'Person', ['first_name', 'last_name']);
console.log(result);

let client = FalkorDB::connect_default();
let result = client.drop_constraint("g", "UNIQUE", "NODE", "Person", &["first_name", "last_name"])?;
println!("{}", result);

FalkorDB client = new FalkorDB();
String result = client.dropConstraint("g", "UNIQUE", "NODE", "Person", Arrays.asList("first_name", "last_name"));
System.out.println(result);

redis> GRAPH.CONSTRAINT DROP g UNIQUE NODE Person PROPERTIES 2 first_name last_name
# Output: OK
