在 SQL 服务器上运行此查询时，我收到以下错误：

MySQL 说：文档

#1064 - 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 13 行的 ' titlevarchar(20) CHARACTER SET utf8 NOT NULL, contractTexttext CHAR'附近使用正确的语法

为什么会出现这种情况？

在这一行

      `username` varchar(32) CHARACTER SET utf8 NOT NULL COMMENT 'comment',

为 COMMENT 或 Remove Comment 添加一些评论。下面是工作代码。

 CREATE TABLE IF NOT EXISTS `contracts` (
`contractId` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(32) CHARACTER SET utf8 NOT NULL COMMENT 'comment',
`title` varchar(20) CHARACTER SET utf8 NOT NULL,
`contractText` text CHARACTER SET utf8 NOT NULL,
`date` datetime NOT NULL,
`contractState` tinyint(1) NOT NULL COMMENT '1-Nepatvirtinta, 2- patvirtinta, 3-    
 panaikinta, 4- atmesta',
 PRIMARY KEY (`contractId`),
 UNIQUE KEY `title` (`title`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_lithuanian_ci AUTO_INCREMENT=15 ;

您没有向该username列添加评论。

`username` varchar(32) CHARACTER SET utf8 NOT NULL COMMENT  ,
        add one here---------------------------------------^

或删除COMMENT关键字

只需修复您的表创建以添加显式注释或删除 COMMENT 关键字（如果不需要）。

尝试将其修改为：

CREATE TABLE IF NOT EXISTS `contracts` (
  `contractId` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) CHARACTER SET utf8 NOT NULL COMMENT 'add explicit comment her',
  `title` varchar(20) CHARACTER SET utf8 NOT NULL,
  `contractText` text CHARACTER SET utf8 NOT NULL,
  `date` datetime NOT NULL,
  `contractState` tinyint(1) NOT NULL COMMENT '1-Nepatvirtinta, 2- patvirtinta, 3- panaikinta, 4- atmesta',
  PRIMARY KEY (`contractId`),
  UNIQUE KEY `title` (`title`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_lithuanian_ci AUTO_INCREMENT=15 ;

comment从此行中删除：

`username` varchar(32) CHARACTER SET utf8 NOT NULL , //COMMENT
