mySQL Database: Reset AutoIncrement Fields

Question

while the development of websites we use the database to test & all... which consumes a lot from auto generated (auto increment) attributes series... how to reset everything...

Answer 1

Assuming you're deleting the records when you're done testing, a TRUNCATE command will delete all records and reset the autoincrement value.

Answer 2

ALTER TABLE _TABLE_ AUTO_INCREMENT=1

Answer 3

Another possibility, avoiding transactions and resetting the autoincrement counter could be to combine the select to get the next available id and the insert itself;

INSERT INTO tablename (id, somefield1, somefield2) SELECT max(id)+1, 'test', 5 FROM tablename
