数据不保存 SQLite3 python3.4

问题描述

我目前正在尝试创建一个包含人名和 ip 的 sqlite 数据库虽然我的代码在运行时似乎可以工作，但在运行 SQLite3 ips 后在终端中运行 SELECT * from ips; 时数据没有显示下面是我的代码.它和 SELECT * from ips; 都运行在 ~/Desktop/SQL

I am currently trying to create a sqlite database of peoples names and ipWhile my code seems to work when I run it the data doesn't show up when I run SELECT * from ips; in terminal after running SQLite3 ipsBelow is my code. Both it and the SELECT * from ips; are running in ~/Desktop/SQL

import sqlite3 as sql
import socket
import struct
def iptoint(ip):
    return str(struct.unpack("i",socket.inet_aton(ip))[0])


database = sql.connect("ips")
createTable = True
if createTable:
    database.execute('''CREATE TABLE main.ips
    (FIRST_NAME TEXT PRIMARY KEY NOT NULL,
    SECOND_NAME TEXT NOT NULL,
    IP INT32 NOT NULL);''')

sampleIps = [("Edward","E","60.222.168.44")]
for first,second,ip in sampleIps:
    string = "INSERT INTO ips VALUES ('%s','%s','%s');"%(first,second,iptoint(ip))
    print(string)
    #Printing the string gives me INSERT INTO ips VALUES ('Edward','E','749264444');
    database.execute("INSERT INTO ips VALUES ('%s','%s','%s');"%(first,second,iptoint(ip)))

database.close()

我的电脑运行的是 OSX 10.11.4、python 3.4 和 SQLite 3.14.1

My computer is running OSX 10.11.4, python 3.4 and SQLite 3.14.1

我尝试将 ips 更改为 main.ips 并返回

I have tried changing ips to main.ips and back

推荐答案

您似乎没有提交到数据库.您需要在关闭连接之前提交才能实际保存对数据库的更改.

It doesn't look like you are committing to the database. You need to commit before closing the connection in order to actually save your changes to the database.

database.commit()
