使用pymssql寫入CSV並將列名稱用作標題

Question

我有以下腳本用於i）連接到數據庫，ii）運行查詢，iii）將查詢結果保存為csv，以及iv）通過電子郵件發送輸出。

一切正常，除了我似乎無法將列名作為文件頭作為標題。 我已經瀏覽了SO，但是找不到適合我的解決方案。 我的腳本如下。 任何幫助都會很棒：

import pymssql
import csv
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email import encoders
fromaddr='XXXX@gmail.com'
toaddr='XXXX@gmail.com'
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "This is a test"
body = "This is still a test"
conn = pymssql.connect(server='XXXXXXXXXX.net',
               port=XXXX,
               user='XXXX',
               password='XXXX',
               database='XXXX')
cursor = conn.cursor()
query = 'Select * From Table'
cursor.execute(query)
with open("XXXXXXXX.csv","w") as outfile:
    writer = csv.writer(outfile, quoting=csv.QUOTE_NONNUMERIC)
    for row in cursor:
        writer.writerow(row)
msg.attach(MIMEText(body,'plain'))
filename = "XXXXXX.csv"
attachment = open("XXXXXXXXXXX.csv","rb")
from email.mime.base import MIMEBase
part = MIMEBase('application','octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition',"attachment; filename= %s" % filename)
msg.attach(part)
text = msg.as_string()
server = smtplib.SMTP('smtp.office365.com',587)
server.starttls()
server.login(fromaddr,"XXXXXX")
text = msg.as_string()
server.sendmail(fromaddr,toaddr,text)

Answer 1

根據PyMSSQL遵循的DB-API ，有一個名為.description的游標屬性，您可以在此處使用。

with open("XXXXXXXX.csv","w") as outfile:
    writer = csv.writer(outfile, quoting=csv.QUOTE_NONNUMERIC)
    writer.writerow(col[0] for col in cursor.description)
    for row in cursor:
        writer.writerow(row)

Answer 2

在cursor對象上使用.description並遍歷它，以獲取列名，例如：

colNameList = []
for i in range(len(cursor.description)):
    desc = cursor.description[i]
    colNameList.append(desc[0])

    colNames = ','.join(colNameList)
    print colNames
