问题描述
我有,我想在希伯来语中插入值
SQLite数据库
我不断收到以下错误:
pre>
UnicodeDecodeError:'ascii'编解码器无法解码位置0中的0xd7字节:ordinal
不在范围(128)
我的代码如下:
def fabricate_hebrew_name():
hebrew_names = [u'ירדן',u'יפה',u 'תמי' U 'ענת' U 'רבקה' U 'טלי' U 'גינה' U 'דנה' U 'ימית' U 'אלונה' U 'אילן' U 'אדם',U 'חווה']
return random.sample(names,1)[0] .encode('utf-8')
'p>请注意: runsql
上SQLite数据库
fabricate_hebrew_name执行查询( )
应该返回一个可以在我的SQL查询中使用的字符串。
任何帮助都不胜感激。
您将传统的名称转换为Unicode字符串的字符串格式参数。理想情况下,通过这种方式,弦也应该是Unicode
但fabricate_hebrew_name没有返回Unicode的 - 它返回UTF-8编码的字符串,这是不一样的
所以,删除这个编码('utf-8')的调用,看看是否有帮助。
下一个问题是runql是什么类型的。如果是期待Unicode,没问题。如果它期待一个ASCII编码的字符串,那么你会有问题,因为希伯来语不是ASCII。在不太可能的情况下,它期待一个UTF-8编码的字符串,然后就是将其转换的时间 - 置换完成后
在另一个答案,伊格纳西奥。 Vazquez-Abrams在查询中警告字符串插值。这里的概念是,使用%运算符,而不是使用字符串替换,通常应该使用参数化查询,并将希伯来语字符串作为参数传递给它。这可能在查询优化和针对SQL注入的安全性方面具有一些优势。
示例
# - * - 编码:utf-8 - * -
import sqlite3
#在内存中创建数据库
conn = sqlite3.connect(:memory: )
cur = conn.cursor()
cur.execute(CREATE TABLE personal(
id INTEGER PRIMARY KEY,
name VARCHAR(42)NOT NULL) )
#insert random name
import random
fabricate_hebrew_name = lambda:random.choice([
u'ירדן',u'יפה',u'תמי ''你''你''你''你',你'你',你'你',你'你' ,$'
$ b cur.execute(INSERT INTO personal VALUES(
NULL,,name),dict(name = fabricate_hebrew_name()))
conn.commit()
ID,名称= cur.execute( SELECT * FROM个人)fetchone()
打印编号,名称

I have sqlite database which I would like to insert values in Hebrew to
I am keep getting the following error :
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd7 in position 0: ordinal
not in range(128)
my code is as following :
def fabricate_hebrew_name():
hebrew_names = [u'ירדן',u'יפה',u'תמי',u'ענת',u'רבקה',u'טלי',u'גינה',u'דנה',u'ימית',u'אלונה',u'אילן',u'אדם',u'חווה']
return random.sample(names,1)[0].encode('utf-8')
note: runsql
executing the query on the sqlite databasefabricate_hebrew_name()
should return a string which could be used in my SQL query.any help is much appreciated.
You are passing the fabricated names into the string formatting parameter for a Unicode string. Ideally, the strings passed this way should also be Unicode.
But fabricate_hebrew_name isn't returning Unicode - it is returned UTF-8 encoded string, which isn't the same.
So, get rid of the call the encode('utf-8') and see whether that helps.
The next question is what type runsql is expecting. If it is expecting Unicode, no problem. If it is expecting an ASCII-encoded string, then you will have problems because the Hebrew is not ASCII. In the unlikely case it is expecting a UTF-8 encoded-string, then that is the time to convert it - after the substitution is done.
In another answer, Ignacio Vazquez-Abrams warns against string interpolation in queries. The concept here is that instead of doing the string substitution, using the % operator, you should generally use a parameterised query, and pass the Hebrew strings as parameters to it. This may have some advantages in query optimisation and security against SQL injection.
Example
# -*- coding: utf-8 -*-
import sqlite3
# create db in memory
conn = sqlite3.connect(":memory:")
cur = conn.cursor()
cur.execute("CREATE TABLE personal ("
"id INTEGER PRIMARY KEY,"
"name VARCHAR(42) NOT NULL)")
# insert random name
import random
fabricate_hebrew_name = lambda: random.choice([
u'ירדן',u'יפה',u'תמי',u'ענת', u'רבקה',u'טלי',u'גינה',u'דנה',u'ימית',
u'אלונה',u'אילן',u'אדם',u'חווה'])
cur.execute("INSERT INTO personal VALUES("
"NULL, :name)", dict(name=fabricate_hebrew_name()))
conn.commit()
id, name = cur.execute("SELECT * FROM personal").fetchone()
print id, name
# -> 1 אלונה
