前言

怎么又是这个错，感觉似曾相识之前遇到过多次了。是的这就是mysql语句报错1064 - You have an error in your SQL 。syntax;...near...感觉每次不管什么原因，都是报的类似错误呢。。。

本文旨在整理开发过程中遇到的类似的错误，并持续更新。

1.新建表时报错

1064 - 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 ') ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户作品表'' at line 15  

 建表语句如下：

CREATE TABLE `user_work`` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '自增主键',
  `is_deleted` tinyint(1) NOT NULL DEFAULT '0' COMMENT '是否删除 0-未删除 1-删除',
  `gmt_create` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `gmt_modify` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '修改时间',
  `version` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '版本号',
  `user_name` int(2) NOT NULL,
  `sex` varchar(32) NOT NULL,
  `code` bigint(20) NOT NULL,
  `lesson_id` bigint(20) NOT NULL,
  `work_id` bigint(20) NOT NULL,
  `grade` bigint(20) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `fk_userId` (`pin`) USING BTREE,
  KEY `fk_work_id` (`lesson_time_id`) USING BTREE,
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户作业';

原因：mysql语句错误，14行末尾多了个逗号，去掉即可。

2.mysql保留关键字报错 ERROR 1064 (42000)

执行语句：

select * from answer where analyze = '真棒'

报错：

ERROR 1064 (42000): 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 'analyze = '真棒'' at line 1

解决方法：
1、若使用了mysql的保留字，需要将其用反引号引起来。
mysql> select * from cfg_parameter where `analyze`='真棒';

2、项目中用的数据库插件可能是自动生成代码，简化了手写，这样的话生成的sql关键字无法带引号。建议不要在创建表的过程中使用mysql保留字，避免后期造成麻烦。

mysql保留关键字列表：

mysql保留关键字

现在使用navicat图形界面或者Hibernate做映射生成表的时候，渐渐的会忽视掉关键字这个问题，而后续也会不断的产生错误提示，一遍遍的查询代码无果，甚至开始怀疑人生，但是其实很多情况下只是使用了保留字而已，因此在设计数据库之初便要尽量的规避关键字和保留字。

但是这里要提一下的是mysql是支持使用关键字做字段名的，但是针对保留关键字是必须要加引用。mysql官网提供了三个例子是可以很好的说明这些的。

interval begin、end都是关键字，interval是保留关键字，因此会报错
mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax ...
near 'interval (begin INT, end INT)'

当给interval加上引用''后便可以正确执行该sql语句，也不会报begin、end的错，因为这是mysql允许的，但是不推荐这个用法，谁知道升级之后会不会变成保留字。。。。。。

mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

（这个可以略过，，，，，反正不推荐使用关键字做这些事，）还有一种情况——内置函数的名字，官网是这样说的：

Names of built-in functions are permitted as identifiers but may require care to be used as such

mysql> CREATE TABLE mydb.interval (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

下面是最新版的mysql的关键字和保留字的表，可以在设计时多查一查，（R）是保留关键字

有些人可能还不明白关键字和保留字的区别，简单的说，关键字分两种：非保留和保留，保留关键字又有一个特殊类别叫未来保留。
