Database referenc Using java code

[mohit sharma]

db.Job.insert({"job_Title" : "Website", "job_Location" : "Kolkata", "salary" : "40000", "company" : "ROHIT", "department" : { "$ref": "department", "$id": ObjectId("579302282d180c1b80be65ec"), "$db": "test"}, "status":"Act"})

 var job = db.Job.findOne({"company":"LOKI"})

 var dep = job.department

 db[dep.$ref].findOne({"_id":(dep.$id)})
How we write this mongoDB shell query in Java program for insert and find Document?

Hi Mohit,

Please see the Mongo Java Driver quick tour documentation, it covers your scenarios.

You can even use the Document.parse(json) method to create the documents from extended json, if that is preferable to using the append methods.

All the best,

Ross
