could not insert data into "mediumtext" field

[tashi tobgay]

this is my mysql query,

INSERT INTO tbl_content( CONTENT_CATEGORY_ID, CONTENT_SECTION_ID, TITLE, INTROTEXT, FULLTEXT, CREATED) VALUES( "2", "6","tryyyyy", "jkl;jkl", "adsf", "asdfgg" );

but its not inserting data into the field "INTROTEXT" and "FULLTEXT" and both of these fields are of "mediumtext" datatype.


and here is my create table query,

CREATE TABLE `tbl_content` (
`CONTENT_ID` int(11) NOT NULL AUTO_INCREMENT,
`CONTENT_CATEGORY_ID` int(11) NOT NULL,
`CONTENT_SECTION_ID` int(11) NOT NULL,
`TITLE` varchar(255) collate latin1_general_ci NOT NULL,
`INTROTEXT` mediumtext NOT NULL,
`FULLTEXT` mediumtext NOT NULL,
`CREATED` datetime NOT NULL,
`CREATED_BY` varchar(255) collate latin1_general_ci NOT NULL,
`MODIFIED` datetime NOT NULL,
`MODIFIED_BY` varchar(255) collate latin1_general_ci NOT NULL,
PRIMARY KEY (`CONTENT_ID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;

...

anything wrong with it?
