生成 SQL 脚本,然后运行它
如果您不想使用复杂的解决方案,例如sqlalchemy
,以下方法是可能的。
- 拥有您的 csv 数据,将它们转换为 SQL 脚本
- 使用 mysql 命令行工具运行此脚本
在你第一次做之前,确保你在数据库中创建了需要的数据库结构(这个我留给你)。
我的以下示例使用(只是为了方便) package docopt
,因此您需要安装它:
$ pip install docopt
CSV 到 SQL 脚本转换实用程序
csv2sql.py
:
"""
Usage:
csv2sql.py [--table <tablename>] <csvfile>
Options:
--table <tablename> Name of table in database to import into [default: mytable]
Convert csv file with iperf data into sql script for importing
those data into MySQL database.
"""
from csv import DictReader
from docopt import docopt
if __name__ == "__main__":
args = docopt(__doc__)
fname = args["<csvfile>"]
tablename = args["--table"]
headers = ["timestamp",
"server_ip",
"server_port",
"client_ip",
"client_port",
"tag_id",
"interval",
"transferred",
"bandwidth"
]
sql = """insert into {tablename}
values ({timestamp},"{server_ip}",{server_port},"{client_ip}",{client_port},{tag_id},"{interval}",{transferred},{bandwidth});"""
with open(fname) as f:
reader = DictReader(f, headers, delimiter=",")
for rec in reader:
print(sql.format(tablename=tablename, **rec)) # python <= 2.6 will fail here
将 CSV 转换为 SQL 脚本
首先让转换实用程序介绍:
$ python csv2sql.py -h
Usage:
csv2sql.py [--table <tablename>] <csvfile>
Options:
--table <tablename> Name of table in database to import into [default: mytable]
Convert csv file with iperf data into sql script for importing
those data into MySQL database.
将您的数据保存在文件中data.csv
:
$ python csv2sql.py data.csv
insert into mytable
values (20140422105054,"172.16.10.76",41065,"172.16.10.65",5001,6,"0.0-20.0",73138176,29215083);
insert into mytable
values (20140422105054,"172.16.10.76",5001,"172.16.10.65",56254,4,"0.0-20.0",46350336,18502933);

insert into mytable
values (20140422105100,"172.16.10.76",5001,"172.16.10.50",58447,5,"0.0-20.1",50937856,20292796);
insert into mytable
values (20140422105553,"172.16.10.76",5001,"172.16.10.65",47382,7,"0.0-20.1",51118080,20358083);
insert into mytable
values (20140422105553,"172.16.10.76",41067,"172.16.10.65",5001,5,"0.0-20.1",76677120,30524007);
insert into mytable

insert into mytable

insert into mytable

将其全部放入文件中data.sql
:
$ python csv2sql.py data.csv > data.sql
应用于data.sql
您的 MySQL 数据库
最后使用mysql
命令(由 MySQL 提供)导入数据库:
$ myslq --user username --password password db_name < data.sql
