Any other way to import data files(like .csv) in p

问题:

In sqlite3's client CLI, there is " .import file TABLE_name " to do it.

But, I do not want to install sqlite3 to my server at present.

In python sqlite3 module, we can creat and edit a DB.

But, I have not found a way to import data-file to a TABLE, except inserting rows one by one.

Any other way?

回答1:

You could insert at one shot using executemany command instead of inserting one by one

Lets say I have users.csv with following contents

"Hugo","Boss"
"Calvin","Klein"

and basically open with csv module and pass it to .executemany function

import csv,sqlite3

persons= csv.reader(open("users.csv"))
con = sqlite3.connect(":memory:")

con.execute("create table person(firstname, lastname)")
con.executemany("insert into person(firstname, lastname) values (?, ?)", persons)

for row in con.execute("select firstname, lastname from person"):
    print row

#(u'Hugo', u'Boss')
#(u'Calvin', u'Klein')
