[Sammy] In the manual (http://www.mysql.com/doc/B/L/BLOB.html), it said
"In most respects, you can regard a TEXT column as a VARCHAR column that
can be as big as you like.
In the manual (http://www.mysql.com/doc/C/R/CREATE_TABLE.html), in the
create table syntax, you can see you don't need to specify the size of a
blob column.
The max size of a blob column is defined in the manual
(http://www.mysql.com/doc/S/t/Storage_requirements.html)

[Sammy] In the manual
(http://www.mysql.com/doc/C/o/Command-line_options.html), you can see
the definition of max_allowed_packet.
