写入数据到excel

Question

我有我需要导出到excel的数据，我只是不知道如何去做，这里是我使用的视图，我已经评论了我的尝试。正确的方向将不胜感激。

Answer 2

你可以直接从MySQL记录写CSV，

import csv 
csv_writer = csv.writer(open(FILENAME,'w'), delimiter=',',quotechar="'") 

data = cursor.fetchall() 
for row in data: 
    csv_writer.writerow(row) 

在

http://snipplr.com/view/11970/simple-csv-dump-script/

SELECTQ="SELECT * FROM category" 
FILENAME="dump.csv" 

import MySQLdb 
import csv 

db = MySQLdb.connect(host="localhost", user="root", passwd="", db="sakila") 
dump_writer = csv.writer(open(FILENAME,'w'), delimiter=',',quotechar="'") 
cursor = db.cursor() 
cursor.execute(SELECTQ) 
result = cursor.fetchall() 
for record in result: 
    dump_writer.writerow(record) 

db.close()
