Sir is your playlist is sufficient to learn mongodb ...as a node js developer
It will help you to query the database directly and basic understanding of mongodb. Then you have to learn mongoose which makes node js to connect and query the database.
Hey,
Is there any platform available where we can practice mongodb queries.
Check last video of the playlist
Bhaiya meine mongo db abhi start kara hai kuch tips dedo jisse mein issey achhe se seekh jaaun
his voice🔥🔥🔥🔥
Problem statement :
In a Json file or Mongo there is an Object contains Company name and Gender,
You Have to find the count of female and male in a seperate column for each company.
ex:
Company Male female
A 22 10
B 20 18
C 10 30
Help me to write the aggregation for better understanding
const employees = await Employee.aggregate([
{
$group: {
_id: { companyName: "$companyName", gender: "$gender" },
count: { $sum: 1 },
},
},
{
$project: {
_id: 0,
companyName: "$_id.companyName",
gender: "$_id.gender",
count: 1,
},
},
]);
cant get it why 44 psychos disliked this such legendary video,absolutely fabulous, amazing
kamal
Bro, can you help me? I'm working with a MongoDB database with 5 million records. When I fetch the total count based on sum or query, the query execution is becoming very slow.
Watch indexing video in this playlist
i've watched your video on indexing and have applied the techniques but due to large data collection giving same result is there any other techniques ? @@EngineeringDigest
Please make video on replication also.
if two student have same age and same hobbies then what will be output?

it means you are going to use reserved keyword ( operator )
