mysql 数据库名称，中间带有中划线问题

插入数据时候，引用了数据库名，数据库名中有横线，会提示错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right sy                                                                  ntax to use near '-all.db1(operationuser,operationtime,notes,ebay_id,types)

解决办法：

把数据库名、表名都用反引号引起来就可以了。

比如：

 insert into `db1`.`tbl1`(operationuser,operationtime,notes,ebay_id,types)(select operationuser,operationtime,notes,ebay_id,types from `db2`.`tbl2` where  `operationtime` >1367337600 order by id asc);
