MyISAM
Table Formats
MyISAM
supports 3 different table types. Two of them are chosen
automatically depending on the type of columns you are using. The third,
compressed tables, can only be created with the myisampack
tool.
When you CREATE
or ALTER
a table that doesn't have
BLOB
values, you can force the table format to DYNAMIC
or
FIXED
with the ROW_FORMAT=#
table option. In the future
you will be able to compress/decompress tables by specifying
ROW_FORMAT=compressed | default
to ALTER TABLE
.
See section 13.2.5 CREATE TABLE
Syntax.
