How to change auto-increment initial value using Web2py and MySQL -


i using web2py mysql build database aims record number of entries (like shipping order) date.

for example, today mar 10 2014, , there 4 orders received. upon creating new order, new order number expected 20140310005.

i figured can use auto-increment field in mysql this. can auto deploy code set auto-increment date everyday, tomorrow mar 11 20140311001.

the question is, how can change auto-increment initial value in web2py?

i agree comment tony hopkinson, possible (with myisam table) this:

create table weborder(order_date date not null,          order_sequence int not null auto_increment,          primary key(order_date, order_sequence)) engine=myisam; insert weborder values('2014-03-10', null); insert weborder values('2014-03-10', null); insert weborder values('2014-03-10', null); insert weborder values('2014-03-11', null); select * weborder;

and data this:

"order_date"    "order_sequence" "2014-03-10"    "1" "2014-03-10"    "2" "2014-03-10"    "3" "2014-03-11"    "1"
