Insert field of type Array in MongoDB

[HARRY_76387 (HARRY CARVALHO)]

In the last video “Understanding JSON” the representation of data storage in the “cast” field of the Array type is written “cast”: [“Leonardo DiCaprio”, “Kate Winslet”, “Kathy Bates”]

But the representation of this field in MongoDB is as follows:
cast:
0: “Leonardo DiCaprio”
1: “Kate Winslet”
2: “Kathy Bates”

My question is:
“In an array insert action, do I enter” [“and items separated by commas or indices” 0: Leonardo “,” 1: Kate “,” 2: Kathy "?

Hi @HARRY_76387,

But the representation of this field in MongoDB is as follows:
cast:
0: “Leonardo DiCaprio”
1: “Kate Winslet”
2: “Kathy Bates”

This is just a view in Compass for easier understanding.

My question is:
“In an array insert action, do I enter” [“and items separated by commas or indices” 0: Leonardo “,” 1: Kate “,” 2: Kathy "?

No, whenever you are doing any insert in MongoDB you do not need to specify the position of elements in the array.

For instance, this is how I would insert a document having array fields in my database.

db.col.insertOne({“cast”: [“Leonardo DiCaprio”, “Kate Winslet”, “Kathy Bates”]})

I hope this helps. However, if you still have any query please feel free to get back to us.

Happy Learning

Hi Shubham_Ranjan,

Thank you very much for your explanations! MongoDB is positively surprising me … I’m changing all my paradigms of the oracle “school” and the other relational databases rsrsrsrs

I am learning a lot!
