How to get values greater than a specific value from an embedded list in MongoDB?
To get values greater than a specific value, use $gt along with find(). Let us create a collection with documents −
> db.demo317.insertOne(
... {'id':101,
... 'details':[{'Score':78,Name:"Chris"},
... {'Score':88,Name:"David"}
... ]
... }
... );
{
"acknowledged" : true,
"insertedId" : ObjectId("5e50e69cf8647eb59e562060")
}
> db.demo317.insertOne(
... {'id':102,
... 'details':[{'Score':90,Name:"Chris"},
... {'Score':91,Name:"David"}
... ]
... }
... );
{
"acknowledged" : true,
"insertedId" : ObjectId("5e50e6adf8647eb59e562061")
}Display all documents from a collection with the help of find() method −
> db.demo317.find();
This will produce the following output −
{ "_id" : ObjectId("5e50e69cf8647eb59e562060"), "id" : 101, "details" : [ { "Score" : 78, "Name" : "Chris" }, { "Score" : 88, "Name" : "David" } ] }
{ "_id" : ObjectId("5e50e6adf8647eb59e562061"), "id" : 102, "details" : [ { "Score" : 90, "Name" : "Chris" }, { "Score" : 91, "Name" : "David" } ] }Following is the query to use $gt on the embedded list in MongoDB to get score records greater than 89 −
> db.demo317.find({"details.Score" :{"$gt": 89}});This will produce the following output −
{ "_id" : ObjectId("5e50e6adf8647eb59e562061"), "id" : 102, "details" : [ { "Score" : 90, "Name" : "Chris" }, { "Score" : 91, "Name" : "David" } ] }
