  • Bash中使用MySQL导入导出CSV格式数据[转]

    MySQL中导出CSV格式数据的SQL语句样本如下:

     
    select * from test_info 
    into outfile '/tmp/test.csv' 
    fields terminated by ',' optionally enclosed by '"' escaped by '"' 
    lines terminated by '
    '; 

    MySQL中导入CSV格式数据的SQL语句样本如下:

     
    load data infile '/tmp/test.csv' 
    into table test_info  
    fields terminated by ','  optionally enclosed by '"' escaped by '"' 
    lines terminated by '
    '; 

    里面最关键的部分就是格式参数

    fields terminated by ',' optionally enclosed by '"' escaped by '"' 
    lines terminated by '
    ' 

    这个参数是根据RFC4180文档设置的,该文档全称Common Format and MIME Type for Comma-Separated Values (CSV) Files,其中详细描述了CSV格式,其要点包括:

    (1)字段之间以逗号分隔,数据行之间以 分隔;

    (2)字符串以半角双引号包围,字符串本身的双引号用两个双引号表示。
