Answer 1

I think you can do the following:

1. Disable the foreign key constraint check

   mysql> SET FOREIGN_KEY_CHECKS = 0;
   

2. Truncate your tables

   mysql> TRUNCATE MY_TABLE;
   

3. Enable the foreign key constraint check

   mysql> SET FOREIGN_KEY_CHECKS = 1;
   

I prefer disabling the foreign key constraints temporarily to dropping/recreating them.
