The MySQL manual states that as of MySQL 5.0.2 If the
column cannot take NOT NULL as the value, MySQL defines the column with
no explicit DEFAULT clause. How are the default values then backed-up?
I did not see any statements defining the default values. Will I have
to re-create the
the default values. Will I have
to re-create the default values if my database becomes corrupted?
The statement you quote applies in the absence of an explicit DEFAULT
clause that specifies the default value. I don't know what it means
to back up a default value or re-create them, but I'll guess

Hi Mike,
It's just part of modifying the column to change the DEFAULT value.
e.g. you might use this (changes to NOT NULL and DEFAULT value of
'new'):
ALTER TABLE table MODIFY type ENUM('new','used') NOT NULL DEFAULT 'new';
Hope that helps.
