I want to TRUNCATE some values but I don't want to delete anothers...

I have 3 ids, and the next id will be 14 or something like that... I want that the next id will be 4... How can I do this?

I have one solution but I like other more simple. I can export all the table, truncate it, and later import it. But it's a lot of work. :P

You can set the next auto_increment value after deleting your records with

ALTER TABLE your_table AUTO_INCREMENT = 4;
