这篇文章给大家分享的是有关MYSQL如何使用infile/outfile的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
 
由于现有的东家要求使用MYSQL数据库，所以最近也开始了对MYSQL数据库的进一步的研究，首先介入的当然是一些正常的应用了：
 
outfile/infile的灵活：
 
今天接触了下mysql下的outfile和infile感觉和实际使用很贴切，不像ORACLE那么商业化，任何操作都要封装成自己的接口来实现、操作，MYSQL直接通过一个简单的语句就完成了数据的导入、导出，满足了日常的灵活性与可控性。
 
LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL] INFILE 'file_name.txt'
    [REPLACE | IGNORE]
    INTO TABLE tbl_name
    [FIELDS
        [TERMINATED BY 'string']
        [[OPTIONALLY] ENCLOSED BY 'char']
        [ESCAPED BY 'char' ]
    ]
    [LINES
        [STARTING BY 'string']
        [TERMINATED BY 'string']
    ]
    [IGNORE number LINES]
    [(col_name_or_user_var,…)]
    [SET col_name = expr,…)]

mysql> load data infile 'd:e.txt' replace into table test1;
Query OK, 7 rows affected (0.06 sec)
Records: 7  Deleted: 0  Skipped: 0  Warnings: 0
mysql> load data infile 'd:ab' replace into table test1 FIELDS TERMINATED  by ',' LINES TERMINATED  by ';';
Query OK, 2 rows affected (0.09 sec)
Records: 2  Deleted: 0  Skipped: 0  Warnings: 0
mysql> load data infile 'd:e.txt' replace into table test1 FIELDS TERMINATED  by ',' LINES TERMINATED  by ';' ignore 2
Query OK, 0 rows affected (0.00 sec)
Records: 0  Deleted: 0  Skipped: 0  Warnings: 0
outfile
mysql> select * into outfile 'd:out1.txt' from test1;
Query OK, 23 rows affected (0.00 sec)
mysql> select * into outfile 'd:out2.txt' FIELDS TERMINATED by ',' from test1
    -> ;
Query OK, 23 rows affected (0.00 sec)
mysql> select * into outfile 'd:out3.txt' FIELDS TERMINATED by ',' lines terminated by ';'  from test1
    -> ;
Query OK, 23 rows affected (0.02 sec)
