MySQL autoincrement column jumps by 10- why? -


i have couple tables in created object id either int or bigint, , in both cases, seem autoincrement 10 (ie, first insert object id 1, second object id 11, third object id 21, etc). 2 questions:

  1. why that?

  2. is problem?

check see seed value of autoincrement isn't set 10.

you can check by:

select auto_increment information_schema.tables table_name='the_table_you_want';

as noted elsewhere can change using system variable @@set_auto_increment_increment

set @@auto_increment_increment=1;

if want start values @ number other 1 can go:

alter table tbl auto_increment = 100;

Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head? But today anyone can accomplish this, because anyone can author a blog (and you thought I was going to tell you to work with a mask on, or something).
