大家好，又见面了，我是全栈君。
今天写代码的时候,老是提示在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 ‘describe。
写SQL语句的时候删掉这个字段就不会报错，加上这个字段添加和查询又会报错，纠结了很久，最后终于试着把describe改为describes，可以正常插入数据，也可以正常查询了,后面在网上一查，describe竟然是mysql中的关键词，我们不能用这个作为数据库中的表的字段。
在SQL语句中出现的关键字和保留字 如果要使用人他们的字符意思而不是作为关键字、保留字使用，关键字可以正常使用，但是保留字必须使用`（键盘tab键上面，数字1左边的那个按键）来分割。这个在SQLServer里面是使用[]中括号实现的。所以我们要尽量避免使用关键字和保留字来作为表名和字段名。
create table api_community_pic(
id int(11) unsigned not null auto_increment primary key comment '图片id',
user_id int(11) not null comment '用户id',
title varchar(255) not null default '' comment '图片标题',
`describe` varchar(255) not null default '' comment '图片描述',
s3_url varchar(255) not null default '' comment '图片s3路径',
praise int(10) NOT NULL DEFAULT '0' COMMENT '点赞数',
status tinyint(1) unsigned not null default '0' comment '图片状态: 0 等待审核 1 审核通过 2审核不通过',
created_at int(11) unsigned NOT NULL DEFAULT '0' COMMENT '上传时间'
)comment='图片表';另外附上mysql保留字列表：
