为CSV Sqlite Python脚本提供的绑定数量不正确

Question

我尝试使用python脚本将值插入到我的sqlite表中。

它是完美的工作，直到我试图添加一个名为“信息”的另一列 - 它然后把下面的错误：

You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings 

于是我说：

conn.text_factory = str 

然后我得到这个错误：

Incorrect number of bindings supplied. The current statement uses 7, and there are 3 supplied. 

我认为问题在于这个新的'information'列包含几行te xt所以我可能会错误地将其指定为'文本'。我的Python脚本代码：

import sqlite3; 
from datetime import datetime, date; 
import time 
conn = sqlite3.connect('mynewtable.sqlite3') 
conn.text_factory = str 
c = conn.cursor() 
c.execute('drop table if exists mynewtable') 
c.execute('create table mynewtable(id integer primary key autoincrement, rank integer, placename text, information text, nooftimes integer, visit text, fav integer, year integer)') 

def mysplit (string): 
quote = False 
retval = [] 
current = "" 
for char in string: 
    if char == '"': 
     quote = not quote 
    elif char == ',' and not quote: 
     retval.append(current) 
     current = "" 
    else: 
     current += char 
retval.append(current) 
return retval 

# Read lines from file, skipping first line 
data = open("mynewtable.csv", "r").readlines()[1:] 
for entry in data: 
# Parse values 
vals = mysplit(entry.strip()) 

# Insert the row! 
print "Inserting %s..." % (vals[0]) 
sql = "insert into mynewtable values(NULL, ?, ?, ?, ?, ?, ?, ?)" 
c.execute(sql, vals) 

# Done! 
conn.commit()

似乎您试图重新发明轮子有点在这里:)

尝试使用Python的CSV模块;我已经广泛地使用它，它工作得很好： http://docs.python.org/library/csv.html

它适用于正确形成具有多行文本的csv文件。

编辑：

例如，你可以使用CSV行（这是列表）直接在执行功能：

import csv 
for row in csv.reader(open('allnamesallyearsn.csv')): 
    c.execute(sql, row)

按我的最后一条评论，这里是您使用csv模块发布的代码：

import sqlite3, csv, time 
from datetime import datetime, date 

conn = sqlite3.connect('mynewtable.sqlite3') 
conn.text_factory = str 
c = conn.cursor() 
c.execute('drop table if exists mynewtable') 
c.execute('create table mynewtable(' 
      'id integer primary key autoincrement, ' 
      'rank integer, ' 
      'placename text, ' 
      'information text, ' 
      'nooftimes integer, ' 
      'visit text, ' 
      'fav integer, ' 
      'year integer)') 

sql_insert = "insert into mynewtable values(NULL, ?, ?, ?, ?, ?, ?, ?)" 
csv_reader = csv.reader(open('mynewtable.csv', 'rb')) 
csv_reader.next() # skip headers 
for csv_row in csv_reader: 
    print "Inserting %s..." % (csv_row) 
    c.execute(sql_insert, csv_row) 

conn.commit()
