variable collection name in mongodb shell using javascript

Question

Using the mongo shell which is javascript:

db.collection.insert() 

Can I allow the collections name to be dynamic so as to work with several collections?

Answer 1

From the mongo shell:

You can create variable using var for collection name

var colName = "mytest"

and then execute all the operations on collections as below:

db[colName].find()

db[colName].rename("newName")

etc. This will help you keep your collection name dynamic and can even update it keeping your commands same.

Hope this helps!
