Answer 1

I came here looking for an answer to the Title question "MySQL - Auto Increment after delete" but I could only find an answer for that in the questions

• How to delete certain row from mysql table?
• How to reset AUTO_INCREMENT in MySQL?

By using something like:

DELETE FROM table;
ALTER TABLE table AUTO_INCREMENT = 1;

Note that Darin Dimitrov's answer explain really well AUTO_INCREMENT and it's usage. Take a look there before doing something you might regret.

PS: The question itself is more "Why you need to recycle key values?" and Dolph's answer cover that.
