mysql - Overriding sql table structure -


table 1

create table `test`.`table_1` (   `id` integer unsigned not null auto_increment,   `name` varchar(45),   primary key (`id`) ) engine = innodb;

table 2

create table `test`.`table_2` (   `id` integer unsigned not null auto_increment,   `name` varchar(256) not null,   `number` integer unsigned not null,   primary key (`id`) ) engine = innodb;

the result want get: table 1 , table 2 expected same, table 1 in coworker workspace , want change table 2 without losing data

you can use alter table. should fine:

alter table table_1 modify name varchar(256) not null;  alter table table_1 add number integer unsigned not null;

notes: not nulls assume table empty (for number) , name has no null values. otherwise, need default values.
