如何在Ruby/Rails中使用load命令和MySQL？

在MySQL中，我可以运行：如何在Ruby/Rails中使用load命令和MySQL？

LOAD DATA LOCAL INFILE "/home/pt/test/bal.csv" INTO TABLE bal FIELDS 
TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '"' IGNORE 1 
LINES;

然而，在我的Ruby程序：

str="LOAD DATA LOCAL INFILE "/home/pt/test/bal.csv" INTO TABLE bal 
FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '"' 
IGNORE 1 LINES;" 

puts str 

dbh.query(str)

输出是：

LOAD DATA LOCAL INFILE "/home/pt/test/bal.csv" INTO TABLE bal FIELDS 
TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '"' IGNORE 1 
LINES; 

/home/pt/test/ptb.rb:34:in `query': Field separator argument is not what 
is expected; check the manual (Mysql::Error) 
from /home/pt/test/ptb.rb:34:in `<main>'

有什么不对的代码？

海峡= “LOAD DATA LOCAL INFILE \”/家/ PT /测试/ bal.csv \” INTO TABLE BAL FIELDS '''''''''''''''''''' IGNORE 1 LINES;“ 试试这个会工作.. :) – 2015-08-24 11:55:57

在ENCLOSED BY ' \"'

str="LOAD DATA LOCAL INFILE \"/home/pt/test/bal.csv\" INTO TABLE bal FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 LINES;"

删除空格您还可以找到有用的%Q[]Ruby syntax。它的""模拟，但你不需要逃避"里面的字符串：

str=%Q[LOAD DATA LOCAL INFILE "/home/pt/test/bal.csv" INTO TABLE bal FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 LINES;]

你试过％Q []语法吗？ – 2015-04-02 10:14:23

我已经做了，但它不工作的主要错误是：字段分隔符参数不是预期的;请检查/home/pt/test/ptb.rb:34:in' – 2015-04-02 10:17:26

中的手册（Mysql :: Error）是否可以在不做任何更改的情况下复制并粘贴此代码：dbh.query％Q [LOAD DATA LOCAL INFILE“/ home/pt/test/bal.csv“INTO TABLE bal FIELDS TERMINATED BY'，'ENCLOSED BY''''TERMINATED BY'\ n'IGNORE 1 LINES;] – 2015-04-02 10:21:32
