mongodb _id rename

Question

I am new to mongodb, how do I rename the _id of an entry?

Answer 1

_id is the primary key of mongodb and cannot be renamed.

Answer 2

_id is automatically generated by mongodb if you do not set it, or you can directly give a value, but as for the renaming mentioned by lz, it seems that it is not possible.

Answer 3

Renaming is not possible. If you really want to change the _id, you can try to create a new data and specify the _id, then copy the original data and delete the original data.
