Answer 1

试试这个

CREATE TABLE `testing` (
    `id` INT NOT NULL AUTO_INCREMENT, 
    `date` DATE NOT NULL, 
    `text_1` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, 
    `text_2` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, 
    PRIMARY KEY (`id`) 
) ENGINE = MYISAM ; 

Answer 2

对于autoincrement字段，你应该有某种与其相关的索引。例如：primary key一个缺少

Answer 3

你必须声明你AUTO_INCREMENT字段作为primary key或key。所以，你必须添加PRIMARY KEY (id)或KEY (id)您CREATE TABLE声明：

CREATE TABLE `try`.`testing` ( 
`id` INT NOT NULL AUTO_INCREMENT, 
`date` DATE NOT NULL , 
`text_1` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL , 
`text_2` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, 
PRIMARY KEY (`id`) -- as primary key 
KEY (`id`) -- or as key 
) ENGINE = MyISAM;
