tcp dump between sogod and mysql 5.6.10 and 5.6.14

CREATE TABLE sogocgubgdla00300bc52d4_quick ( c_name VARCHAR(255) NOT
NULL PRIMARY KEY, c_uid VARCHAR(255) NOT NULL, c_startdate INT NULL,
c_enddate INT NULL, c_cycleenddate INT NULL, c_title VARCHAR(1000) NOT
NULL, c_participants VARCHAR(1000000) NULL, c_isallday INT NULL,

c_partstates VARCHAR(255) NULL, c_category VARCHAR(255) NULL,

NULL
);

and mysql responds with

ERROR 1074 (42000): Column length too big for column 'c_participants'
(max = 65535); use BLOB or TEXT instead

and that seems to be true:

c_participants VARCHAR(1000000)

where mysql doc show that varchar max length is 65535
