Find values with OR operator in MongoDB and format the result.?
Use $or operator to fetch values and to format the result, use “pretty()”. Let us create a collection with documents −
> db.demo304.insertOne({"StudentName":"Chris","StudentAge":23}); { "acknowledged" : true, "insertedId" : ObjectId("5e4ea3ccf8647eb59e562034") } > db.demo304.insertOne({"StudentName":"David","StudentAge":22}); { "acknowledged" : true, "insertedId" : ObjectId("5e4ea3d7f8647eb59e562035") } > db.demo304.insertOne({"StudentName":"Mike","StudentAge":24}); { "acknowledged" : true, "insertedId" : ObjectId("5e4ea3e2f8647eb59e562036") } > db.demo304.insertOne({"StudentName":"Carol","StudentAge":22}); { "acknowledged" : true, "insertedId" : ObjectId("5e4ea3eef8647eb59e562037") }
Display all documents from a collection with the help of find() method −
> db.demo304.find();
This will produce the following output −
{ "_id" : ObjectId("5e4ea3ccf8647eb59e562034"), "StudentName" : "Chris", "StudentAge" : 23 } { "_id" : ObjectId("5e4ea3d7f8647eb59e562035"), "StudentName" : "David", "StudentAge" : 22 } { "_id" : ObjectId("5e4ea3e2f8647eb59e562036"), "StudentName" : "Mike", "StudentAge" : 24 } { "_id" : ObjectId("5e4ea3eef8647eb59e562037"), "StudentName" : "Carol", "StudentAge" : 22 }
Following is the query to get values with OR operator in MongoDB −
> db.demo304.find({ $or: [{ "StudentName": "David" }, { "StudentAge":22} ] } ).pretty();
This will produce the following output −
{ "_id" : ObjectId("5e4ea3d7f8647eb59e562035"), "StudentName" : "David", "StudentAge" : 22 } { "_id" : ObjectId("5e4ea3eef8647eb59e562037"), "StudentName" : "Carol", "StudentAge" : 22 }
