使用Python pyodbc

Question

我有一個代碼從SQL Server轉換XML領域爲XML文件：

import pypyodbc as pyodbc 

cnxn = pyodbc.connect(
    'Trusted_Connection=yes;DRIVER={SQL Server};SERVER=localhost;DATABASE=HOLA;UID=sa;PWD=HOLAMUNDO' 
) 

idPerson = 2 

cursor = cnxn.cursor() 
cursor.execute('SELECT * FROM prueba WHERE id=?', (idPerson,)) 
for row in cursor.fetchall(): 
    print(row) 

這工作得很好，並選擇XML領域有下格式：

<PERSON> 
    <INFO> 
    <NAME>Charlie</NAME> 
    <LASTNAME>Brown</LASTNAME> 
    </INFO> 
</PERSON> 

我怎樣才能把這個領域並將其保存在一個新的XML文件中的目錄...？

這是我的數據庫腳本：

USE [HOLA] 
GO 
/****** Object: Table [dbo].[prueba] Script Date: 04/03/2016 8:29:30 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
CREATE TABLE [dbo].[prueba](
    [id] [int] NOT NULL, 
    [xml] [xml] NULL, 
CONSTRAINT [PK_prueba] PRIMARY KEY CLUSTERED 
(
    [id] ASC 
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

GO

import pypyodbc as pyodbc 
import urllib 
from xml.dom.minidom import parse, parseString 
xmlpath = "example.xml" 

cnxn = pyodbc.connect(
    'Trusted_Connection=yes;DRIVER={SQL Server};SERVER=localhost;DATABASE=HOLA;UID=sa;PWD=HOLAMUNDO' 
) 

idPerson = 2 

cursor = cnxn.cursor() 
cursor.execute('SELECT id, xml FROM prueba WHERE id=?', (idPerson,)) 

for row in cursor.fetchall(): 
    print row[1] 

xml = row[1] 

#Generate the xml file from the string 
dom = parseString(xml) 

# Write the new xml file 
xml_str = dom.toprettyxml(indent=" ") 
with open("example.xml", "w") as f: 
    f.write(xml_str)
