mysql数据库创建删除带横杠的数据库名

mysql> create database d-d;

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 '-d' at line 1

1064报错：该错误一般出现在表名或者字段名设计过程中出现了mysql关键字导致的。问题确定是数据库名字的错误，我把横杠去掉以后就可以。

尝试：

create database [d-d];

create database 'd-d';

create database ”d-d“;

create database d\-d;

均报错：
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 '[d-d]' at line 1

解决:create database `d-d`;    加反引号

mysql> create database `d-d`;
Query OK, 1 row affected (0.00 sec)
