How to get multiple document using array of MongoDb id?
MongodbMongodb Problem Overview
I have an array of ids and I want to get all document of them at once. For that I am writing but it return 0 records.
How can I search using multiple Ids ?
db.getCollection('feed').find({"_id" : { "$in" : [
"55880c251df42d0466919268","55bf528e69b70ae79be35006" ]}})
I am able to get records by passing single id like
db.getCollection('feed').find({"_id":ObjectId("55880c251df42d0466919268")})
Mongodb Solutions
Solution 1 - Mongodb
MongoDB is type sensitive, which means 1 is different with '1', so are "55880c251df42d0466919268" and ObjectId("55880c251df42d0466919268"). The later one is in ObjectID type but not str, and also is the default _id type of MongoDB document.
You can find more information about ObjectID here.
Just try:
db.getCollection('feed').find({"_id" : {"$in" : [ObjectId("55880c251df42d0466919268"), ObjectId("55bf528e69b70ae79be35006")]}});
Solution 2 - Mongodb
I believe you are missing the ObjectId. Try this:
db.feed.find({
_id: {
$in: [ObjectId("55880c251df42d0466919268"), ObjectId("55bf528e69b70ae79be35006")]
}
});
Solution 3 - Mongodb
For finding records of multiple documents you have to use "$in" operator Although your query is fine, you just need to add ObjectId while finding data for Ids
db.feed.find({
"_id" : {
"$in" :
[ObjectId("55880c251df42d0466919268"),
ObjectId("55bf528e69b70ae79be35006")
]
}
});
Solution 4 - Mongodb
Just I have use it, and is working fine:
module.exports.obtenerIncidencias386RangoDias = function (empresas, callback) {
let arraySuc_Ids = empresas.map((empresa)=>empresa.sucursal_id)
incidenciasModel.find({'sucursal_id':{$in:arraySuc_Ids}
}).sort({created_at: 'desc'}).then(
(resp)=> {
callback(resp)}
)
};
where:
empresas = ["5ccc642f9e789820146e9cb0","5ccc642f9e789820146e9bb9"]
Solution 5 - Mongodb
store array list in var and pass that array list to find function var list=db.collection_name.find() db.collection_name.find({_id:{$in:list}})
Solution 6 - Mongodb
The Id's need to be in this format : ObjectId("id").
you can use this to transform your string ID's :
const ObjectId = require('mongodb').ObjectId;
Solution 7 - Mongodb
db.getCollection({your_collection_name}).find({
"_id" : {
"$in" :
[({value1}),
({value2})
]
}
})
