How to use firebase realtime database and firebase firestore database in the same file.js because both modules use a query variable and it is conflicting when importing both modules in the same file.

e.g query imported from "firebase/database"

import { getDatabase, ref, query, orderByChild } from "firebase/database"; 

const mostViewedPosts = query(ref(db, 'posts'), orderByChild('metrics/views'));

e.g query imported from "firebase/firestore"

import { collection, query, where, onSnapshot } from "firebase/firestore";

const q = query(collection(db, "cities"), where("state", "==", "CA"));
