3. Insert sample data¶
In this tutorial you will learn to insert sample data to Percona Server for MongoDB.
MongoDB provides multiple methods for data insert . We will use a For
loop to insert some sample documents.
-
Run the following command:
admin> for (var i = 1; i <= 50; i++) { db.test.insertOne( { x : i } ) }
If there is no
test
collection created, MongoDB creates when inserting documents.Output
{ acknowledged: true, insertedId: ObjectId("652567e5eedca48f97e1868f") }
-
Query the collection to verify the data insertion
admin> db.test.find()
Output
[ { _id: ObjectId("652567e4eedca48f97e1865e"), x: 1 }, { _id: ObjectId("652567e4eedca48f97e1865f"), x: 2 }, { _id: ObjectId("652567e4eedca48f97e18660"), x: 3 }, { _id: ObjectId("652567e4eedca48f97e18661"), x: 4 }, { _id: ObjectId("652567e4eedca48f97e18662"), x: 5 }, { _id: ObjectId("652567e4eedca48f97e18663"), x: 6 }, { _id: ObjectId("652567e4eedca48f97e18664"), x: 7 }, { _id: ObjectId("652567e4eedca48f97e18665"), x: 8 }, { _id: ObjectId("652567e4eedca48f97e18666"), x: 9 }, { _id: ObjectId("652567e4eedca48f97e18667"), x: 10 }, { _id: ObjectId("652567e4eedca48f97e18668"), x: 11 }, { _id: ObjectId("652567e4eedca48f97e18669"), x: 12 }, { _id: ObjectId("652567e4eedca48f97e1866a"), x: 13 }, { _id: ObjectId("652567e4eedca48f97e1866b"), x: 14 }, { _id: ObjectId("652567e4eedca48f97e1866c"), x: 15 }, { _id: ObjectId("652567e4eedca48f97e1866d"), x: 16 }, { _id: ObjectId("652567e4eedca48f97e1866e"), x: 17 }, { _id: ObjectId("652567e4eedca48f97e1866f"), x: 18 }, { _id: ObjectId("652567e4eedca48f97e18670"), x: 19 }, { _id: ObjectId("652567e4eedca48f97e18671"), x: 20 } ]
You will have different
_id
values.
Now your cluster has some data in it.
