Question

 CREATE TABLE `mytable` (
`cid` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`ckey` TINYTEXT UNSIGNED NOT NULL ,
`cdate` TINYTEXT UNSIGNED NOT NULL ,
`ctime` TINYTEXT UNSIGNED NOT NULL ,
`cuser` TINYTEXT UNSIGNED NOT NULL ,
`ctext` LONGTEXT UNSIGNED NOT NULL ,
`cstatus` TINYTEXT UNSIGNED NOT NULL
) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci

MySQL说：

1064 - 您的SQL语法出错;查看与您的MySQL服务器版本相对应的手册，以便在第1行使用“UNSIGNED NOT NULL，cdate TINYTEXT UNSIGNED NOT NULL，ctime TINYTEXT UNSIGNED”附近使用正确的语法

更新了完整代码：

$query = "
CREATE TABLE mytable (
  cid INT(1) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
  ckey TINYTEXT(10) NOT NULL ,
  cdate TINYTEXT(10) NOT NULL ,
  ctime TINYTEXT(10) NOT NULL ,
  cuser TINYTEXT(10) NOT NULL ,
  ctext LONGTEXT(10) NOT NULL ,
  cstatus TINYTEXT(10) NOT NULL
 ) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci AUTO_INCREMENT = 1;";

Answer 1

您必须指定字符串最大长度，例如：

CREATE TABLE `mytable` (
`cid` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`ckey` TINYTEXT(10) UNSIGNED NOT NULL ,
`cdate` TINYTEXT(10) UNSIGNED NOT NULL ,
`ctime` TINYTEXT(10) UNSIGNED NOT NULL ,
`cuser` TINYTEXT(10) UNSIGNED NOT NULL ,
`ctext` LONGTEXT(10) UNSIGNED NOT NULL ,
`cstatus` TINYTEXT(10) UNSIGNED NOT NULL
) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci

其中10是你的价值。希望有用

Answer 2

我不知道它是否回答了这个问题，因为我尝试通过php而且它没有工作所以我直接做了

CREATE TABLE `mytable` (
`cid` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`ckey` TINYTEXT NOT NULL ,
`cdate` TINYTEXT NOT NULL ,
`ctime` TINYTEXT NOT NULL ,
`cuser` TINYTEXT NOT NULL ,
`ctext` TEXT NOT NULL ,
`cstatus` TINYINT UNSIGNED NOT NULL
) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci;

SQL语法中的错误检查与MySQL服务器版本对应的手册
