How to copy a row

Hi Arnaud and mORMot community,

I'd like to make a copy of an entry in my db, is there a way to do it in the "mORMot way" without having to first create the object and then re-post it with a new ID?

Thanks in advance!

@StxLog,

I don't think so, reading the original object, cloning it and then saving it back to the DB with a new ID would be the way to go.

In addition, consider two things:
- Use a TSQLRestBatch for faster writing process;
- Reuse the same TSQLRecord instance during the addition loop to avoid memory re-allocation.
