mysql 數據庫名稱，中間帶有中划線問題

插入數據時候，引用了數據庫名，數據庫名中有橫線，會提示錯誤：

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)

解決辦法：

把數據庫名、表名都用反引號引起來就可以了。

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);
