在mysql中，excel文件数据的导出和导入

数据的导出：

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

你就可以在盘根目录下，发现mytable.xls文件

数据的导入：

用导出的表mytable.xls导入：输入命令：load data infile 'd:/mytable.xls' into table mytable;

注释：mytable ：是数据库的表名

当数据库中的表有主键和自增字段时，会报错，数据无法添加，解决方案：

1. 把mytable.xls表中的自增并且主键的那一列删除掉
2. 输入命令：load data infile 'd:/mytable.xls' into table mytable(name,count);即可。数据是追加进去的，不是覆盖
3. 自增字段 ：auto_increment,主键：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}] ...]
