can I reset auto_increment field in mySql?

Question

Can I reset the auto-increment index of a MySQL table so that it starts counting from zero again?

I deleted all the rows in the table--how can I reset that counter as well?

Answer 1

Or just truncate the table instead of deleting the roles -- that drops and re-adds the table, resetting the autoincrement values in the process

Answer 2

To delete all rows from a MySQL table AND reset the auto_increment value, use the truncate command.
