＃1075 MySQL错误

Question

So i am just a beginner in all this php stuff. I know just the basics, and when i setting up the settings for my new table, I met the problem #1075. Before, i created one, almost similar to this one, and i don't see the differenc. Can you say me where is the problem and explain what is happening?

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 ) ENGINE = MyISAM;

here is the code of my SQL Preview. I use phpMyAdmin, obviously. Please, help me. Thank, you)

Answer 1

Try this

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

You have to declare your AUTO_INCREMENT field as a primary key or a key . So you have to add PRIMARY KEY (id) or KEY (id) to your CREATE TABLE statement:

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;

Answer 3

For an autoincrement field you should have some sort of index associated with it. eg: primary key which is missing

Answer 4

Try This.

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,
KEY (`id`) 
) ENGINE = MyISAM;
