MongoDB: How to find the relationship of collections

[Nimatullah Razmjo]

I have a collection of whichuser hasid, firstName, lastName the idfield of the collectionuser has been used in another collection.

Is there any way to find all collection which used user id

[Leszek R]

I think you are thinking of mongo collections like a rdbms tables which they are not. Collections do not have schemas defined in them, so they don't keep list of fields used.
Also the list of fields can change from document to document.

To answer your question: There is no way to find all collections that have field "user id" without scanning all documents in all collections.

Thank you

Schema is dynamically used , we cannot find user id in  all the collections . We can check individually in one collection at a time.

Pleas let me know if you need issues
