mysql auto_increment by 5?

Question

I\'m running into a really, really, really weird problem with mysql.

I have a primary key, \"id\". It\'s set to auto increment. Problem is, first entry started at \"

Answer 1

There's a my.cnf configuration for that: auto_increment_increment. It's used for master-master server setups to prevent the same key from being defined twice by two different servers. So using that coupled with auto_increment_offset, it allows each server to always generate unique ids...

So, from what you're describing, it sounds like you have this:

auto_increment_increment = 5
auto_increment_offset = 3

Answer 2

The auto increment is probably set to 5. Try:

ALTER TABLE YourTable AUTO_INCREMENT = 1;

You can retrieve the current setting with:

SHOW TABLE STATUS LIKE 'YourTable'

See the MySQL docs for more details.

Answer 3

it appears the table was created with an increment set to 5. you can change it back to one with the following:

ALTER TABLE tbl AUTO_INCREMENT = 1;
