When using MongoDB, some fields need to be self-increment, and are denoted by two decimal letters (using A-T corresponds to 0-19), do a _auto_increment field to save, but should start from 0 or 1?

Consistent with MySQL for easy maintenance. So try it. Mysql,auto_increment is starting from 1. It seems that a can not be used, starting from B, such as B, C......s, T, BA, Bb......bs, Bt.

Code:

Create TableUsers (IDint(Ten) unsigned not NULLAuto_incrementPrimary Key, namevarchar( -) not NULL); showCreate Tableusers;Insert  intoUsers (name)Values('Jim'); showCreate Tableusers;Select *  fromUsers

Verify: MySQL auto_increment default value is 1
