I have just tried to set the below table in a MYSQL database, but when I do the show columns from, all of the columns of which I have set to with 'CHAR', are all shown as 'VARCHAR", and the table is listed as 'dynamic' rather than 'fixed'

What is going on?
Is there some variable of which is confusing the system in some way?

CREATE TABLE watchregcontact (
wtcctsp TIMESTAMP,
wtccip CHAR(20),
wtccjacn INT UNSIGNED,
wtccrow BIGINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
wtccdte DATETIME,
wtccmt CHAR(10),
wtccmr CHAR(8),
wtcchead CHAR(50),
wtccmbod TEXT,
wtccpd DATETIME,
wtccpb TINYTEXT,
wtccfd DATETIME,
wtccfb TEXT,
wtccpi CHAR(20),
wtccpu CHAR(30),
wtccfi CHAR(20),
wtccfu CHAR(30)
);

if you have several CHAR columns with differing widths MySQL will optimise them all as VARCHAR types. This will save space in the database as CHAR columns are padded with spaces to fill the specified width but VARCHAR are not.
So a 10 character string in a 50 wide CHAR column will take up 50 bytes but as a VARCHAR will only take up 11 bytes
