the table, unnamed columns are set to their default values.  Default value















assignment is described in @ref{CREATE TABLE, , @code{CREATE TABLE}}.



























You can also use the keyword @code{DEFAULT} to set a column to it's













defaults value. (New in MySQL 4.0.3).  This makes it easier to write













insert statements as you don't have to use a field-name list just because













you don't want to set a value for a few columns.



























MySQL always has a default value for all fields. This is something















that is imposed on MySQL to be able to work with both transactional















and not transactional tables.
