python读取数据库表数据并写入excel

cur = conn.cursor()

1 sql = ‘select * from %s;‘ %table_name #需要写入excel表数据
2 #读取数据
3 cur.execute(sql) #读取数据
4 fileds = [filed[0] for filed in cur.description] #读取表结构定义
5 all_date = cur.fetchall() #所有数据
6 for result in all_date:

 1     book = xlwt.Workbook() #创建一个book

 3     sheet = book.add_sheet(‘result‘) #创建一个sheet表

 5     for col,filed in enumerate(fileds):
 6         sheet.write(0,col,filed)  #将表字段描述写入excel第一行
