Selecting database inside the js in mongoDB

Question

I can run the script in the specific database like

 mongo main myscript.js<br/>

where main is a database name. The same thing I am unable to run inside the script like

myscript.js

 use main;   // not taking, throw error when using "mongo myscript.js"

Answer 1

Use this in your script

db = db.getSiblingDB('main');

The default DB is test. This statement gets a "sibling" database of test.
