MYSQL查詢錯誤

Question

這段代碼有什麼問題嗎？我運行MySQL 5我不斷收到此錯誤：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL
server version for the right syntax to use near 'desc BLOB, review BLOB, url BLOB)'

這裏是我的查詢：

mysql_query("CREATE TABLE videos(
       id INT NOT NULL AUTO_INCREMENT, 
       PRIMARY KEY(id), 
       title VARCHAR(50), 
       desc BLOB, 
       review BLOB, 
       url BLOB 
      ) 
") or die(mysql_error()); 

它看起來好了給我。起初我以爲是「BLOB」數據類型，但後來我嘗試了「TEXT」，但它仍然搞砸了，所以我不太確定。

Answer 1

desc是保留關鍵字，你需要逃避它：

mysql_query("CREATE TABLE videos(
       id INT NOT NULL AUTO_INCREMENT, 
       PRIMARY KEY(id), 
       title VARCHAR(50), 
       `desc` BLOB, 
       review BLOB, 
       url BLOB 
      ) 
")or die(mysql_error());

Answer 2

嘗試：

mysql_query("CREATE TABLE videos(
       `id` INT NOT NULL AUTO_INCREMENT, 
       PRIMARY KEY(id), 
       `title` VARCHAR(50) NULL, 
       `desc` BLOB NULL, 
       `review` BLOB NULL, 
       `url` BLOB NULL 
      ) 
")or die(mysql_error()); 

Answer 3

desc MySQL保留關鍵字，你應該用反引號覆蓋它：

CREATE TABLE videos (
id INT NOT NULL AUTO_INCREMENT, 
`title` VARCHAR(50), 
`desc` BLOB, 
`review` BLOB, 
`url` BLOB, 
PRIMARY KEY (`id`) 
)
