Hello to all,

I have a table with MyISAM engine, with a key with more fields (year, customer idricevuta) auto_increment
When I add a field in automatic I read this becomes id is in receipt number.


But if I delete the fields I would like the next record inserted reuse index not used.

an example:

id user year
1 aaaa 2014 ...
2 aaaa 2014 ...
1 bbbb 2014 ...
2 bbbb 2014
3 bbbb 2014

if I delete record 2 aaaa 2014, and I insert two new a record I would like to have

id user year
1 aaaa 2014
2 aaaa 2014 new
1 bbbb 2014
2 bbbb 2014
3 bbbb 2014
3 aaaa 2014 new

do you think i can do?
