将 csv 文件加载到 MySql 中的 Python 3.4 代码

Question

我是 Python 新手，我正在使用 python 3.4，想编写一个脚本来将数据从 csv 文件（只有 2 个 cols-emp_id、emp_name）加载到 MySQL 数据库表中。 有人有示例代码吗？ 请帮忙。

您不需要为此使用 Python。 你甚至不需要一个程序。 MySQL 有一个用于读取 CSV 文件的语句。

请参阅： https : //dev.mysql.com/doc/refman/5.1/en/load-data.html ，来自文档：

LOAD DATA INFILE can be used to read files obtained from external sources. For
example, many programs can export data in comma-separated values (CSV) format,
such that lines have fields separated by commas and enclosed within double
quotation marks, with an initial line of column names. If the lines in such a
file are terminated by carriage return/newline pairs, the statement shown here
illustrates the field- and line-handling options you would use to load the file:

LOAD DATA INFILE 'data.txt' INTO TABLE tbl_name
  FIELDS TERMINATED BY ',' ENCLOSED BY '"'
  LINES TERMINATED BY '\r\n'
  IGNORE 1 LINES;

If the input values are not necessarily enclosed within quotation marks, use
OPTIONALLY before the ENCLOSED BY keywords.

除此之外，MySQL 还附带了一个名为mysqlimport 的程序，它也可以做到这一点。
