MongoDB query for fields in embedded document?
Let us first create a collection with documents −
> db.embeddedDocumentDemo.insertOne(
... {
... "CustomerDetails":[
... {"CustomerName":"Chris", "CustomerPurchasePrice":3000},
... {"CustomerName":"Robert", "CustomerPurchasePrice":4500},
... {"CustomerName":"David", "CustomerPurchasePrice":1000},
... ]
... }
... );
{
"acknowledged" : true,
"insertedId" : ObjectId("5cd32347edc6604c74817ccd")
}Following is the query to display all documents from a collection with the help of find() method −
> db.embeddedDocumentDemo.find().pretty();
This will produce the following output −
{
"_id" : ObjectId("5cd32347edc6604c74817ccd"),
"CustomerDetails" : [
{
"CustomerName" : "Chris",
"CustomerPurchasePrice" : 3000
},
{
"CustomerName" : "Robert",
"CustomerPurchasePrice" : 4500
},
{
"CustomerName" : "David",
"CustomerPurchasePrice" : 1000
}
]
}Following is the query for embedded document −
> db.embeddedDocumentDemo.find({"CustomerDetails.CustomerPurchasePrice":4500});This will produce the following output −
{ "_id" : ObjectId("5cd32347edc6604c74817ccd"), "CustomerDetails" : [ { "CustomerName" : "Chris", "CustomerPurchasePrice" : 3000 }, { "CustomerName" : "Robert", "CustomerPurchasePrice" : 4500 }, { "CustomerName" : "David", "CustomerPurchasePrice" : 1000 } ] }
