Find all documents that have two specific id's in an array of objects in MongoDB?
You can use $and operator for this. Let us first create a collection with documents −
> db.twoSpecificIdsDemo.insertOne(
... {
... PlayerId:1,
... "PlayerDetails": [{
... id: 100,
... "PlayerName":"Chris"
... },{
... id: 101,
... "PlayerName":"Sam"
... },{
... id: 102,
... "PlayerName":"Robert"
... },{
... id: 103,
... "PlayerName":"Carol"
... }]
... }
... );
{
"acknowledged" : true,
"insertedId" : ObjectId("5cd3e130edc6604c74817ce4")
}
> db.twoSpecificIdsDemo.insertOne(
... {
... PlayerId:1,
... "PlayerDetails": [{
... id: 104,
... "PlayerName":"Mike"
... },{
... id: 105,
... "PlayerName":"Bob"
... },{
... id: 102,
... "PlayerName":"Ramit"
... },{
... id: 106,
... "PlayerName":"David"
... }]
... }
... );
{
"acknowledged" : true,
"insertedId" : ObjectId("5cd3e167edc6604c74817ce5")
}
Following is the query to display all documents from a collection with the help of find() method −
> db.twoSpecificIdsDemo.find().pretty();
This will produce the following output −
{
"_id" : ObjectId("5cd3e130edc6604c74817ce4"),
"PlayerId" : 1,
"PlayerDetails" : [
{
"id" : 100,
"PlayerName" : "Chris"
},
{
"id" : 101,
"PlayerName" : "Sam"
},
{
"id" : 102,
"PlayerName" : "Robert"
},
{
"id" : 103,
"PlayerName" : "Carol"
}
]
}
{
"_id" : ObjectId("5cd3e167edc6604c74817ce5"),
"PlayerId" : 1,
"PlayerDetails" : [
{
"id" : 104,
"PlayerName" : "Mike"
},
{
"id" : 105,
"PlayerName" : "Bob"
},
{
"id" : 102,
"PlayerName" : "Ramit"
},
{
"id" : 106,
"PlayerName" : "David"
}
]
}
Here is the query to find all documents that have two specific id's in an array of objects in MongoDB −
> db.twoSpecificIdsDemo.find( { $and : [ { "PlayerDetails.id" : 102 }, { "PlayerDetails.id" : 103 } ] } ).pretty();
This will produce the following output −
{
"_id" : ObjectId("5cd3e130edc6604c74817ce4"),
"PlayerId" : 1,
"PlayerDetails" : [
{
"id" : 100,
"PlayerName" : "Chris"
},
{
"id" : 101,
"PlayerName" : "Sam"
},
{
"id" : 102,
"PlayerName" : "Robert"
},
{
"id" : 103,
"PlayerName" : "Carol"
}
]
}
