I am using MySQL 5.0.2 on a Redhat 9 box. I am having problems altering some columns default value and having it show up in the 'show create table x' and backup files. Here is my repeatable example:
I issue this create statement: create table mytable ( a int not null, b int not null, c int ); Then I issue this alter table statement: alter table mytable alter a set default '1'; Then I issue: Show create table mytable; The result is: CREATE TABLE `mytable` ( `a` int(11) NOT NULL, `b` int(11) NOT NULL, `c` int(11) default NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1 However, the behavior works properly. For instance: insert into mytable (b, c) values (2, 3); select * from mytable; produces: 1, 2, 3 I realize of course that I can simply put the default value clause in my create statement, but I don't want to do that because the entire database has already been established and is up and running in a production environment. Am I doing something wrong or is this a bug? Whatever the case, what is the fix? Thank you, Jason McAffee The Technology Group
