數據的導出：

select * from mytable into outfile ‘d:/mytable.xls‘;

你就可以在盤根目錄下，發現mytable.xls文件

數據的導入：

用導出的表mytable.xls導入：輸入命令：load data infile ‘d:/mytable.xls‘ into table mytable;

註釋：mytable ：是數據庫的表名

當數據庫中的表有主鍵和自增字段時，會報錯，數據無法添加，解決方案：

1. 把mytable.xls表中的自增並且主鍵的那一列刪除掉
2. 輸入命令：load data infile ‘d:/mytable.xls‘ into table mytable(name,count)
   ;即可。數據是追加進去的，不是覆蓋
3. 自增字段 ：auto_increment,主鍵：primary_key

4. LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL] INFILE ‘file_name‘
       [REPLACE | IGNORE]
       INTO TABLE tbl_name
       [CHARACTER SET charset_name]
       [{FIELDS | COLUMNS}
           [TERMINATED BY ‘string‘]
           [[OPTIONALLY] ENCLOSED BY
    
    ‘char‘]
           [ESCAPED BY ‘char‘]
       ]
       [LINES
           [STARTING BY ‘string‘]
           [TERMINATED BY ‘string‘]
       ]
       [IGNORE number {LINES | ROWS}]
       [(col_name_or_user_var
           [, col_name_or_user_var] ...)]
       [SET col_name={expr | DEFAULT},
           [, col_name={expr | DEFAULT}
    
   ] ...]
