＃1075 MySQL錯誤

Question

，所以我就在這一切的PHP的東西是初學者。我知道只是基礎知識，當我爲我的新表設置的設置，我遇到的問題＃1075。之前，我創建了一個幾乎與此類似，我沒有看到differenc。你能說我問題在哪裏，並解釋發生了什麼？

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; 

這裏是我的SQL預覽的代碼。顯然，我使用phpMyAdmin。 請幫幫我。 謝謝，你）

Answer 1

試試這個

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

對於autoincrement字段，你應該有某種與其相關的索引。例如：primary key一個缺少

Answer 3

你必須聲明你AUTO_INCREMENT字段作爲primary key或key。所以，你必須添加PRIMARY KEY (id)或KEY (id)您CREATE TABLE聲明：

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;

嘗試。

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,
