利用python将sqlserver的表导入excle

练习，直接上代码

import pymssql
import xlwt
# server    数据库服务器名称或IP
# user      用户名
# password  密码
# database  数据库名称
conn = pymssql.connect('127.0.0.1', 'sa', '123456', 'WC_DONGWANG')

cursor = conn.cursor()
cursor.execute('select * from [dbo].[T__LOG_ALARM]')
#如果update/delete/insert记得要conn.commit()
 #否则数据库事务无法提交
#print (cur.fetchall())
# 搜取所有结果
results = cursor.fetchall()

# 获取sqlserver里面的数据字段名称
fields = cursor.description
workbook = xlwt.Workbook()
sheet = workbook.add_sheet('table_message',cell_overwrite_ok=True)

# 写上字段信息
for field in range(0,len(fields)):
 sheet.write(0,field,fields[field][0])

# 获取并写入数据段信息
row = 1
col = 0
for row in range(1,len(results)+1):
 for col in range(0,len(fields)):
  sheet.write(row,col,u'%s'%results[row-1][col])

workbook.save(r'./readout.xlsx')


cursor.close()
# 关闭连接
conn.close()
