20170529计划---统计业务量并生成EXCEL通过邮件发送

　　每个月都要统计这些业务量的东东，烦死了，赶紧通过python写一个来搞定吧，三天搞定吧，未完待续哈。

2017-5-29 19：50粗略地做了一个思维导图哈

终于第三天完成啦

 #encoding=utf-8
 import cx_Oracle as oracle
 import MYSQLdb as mysql
 from datetime import datetime
 import xlsxwriter
 import sys
 '''
 author:poleaxe
 function:实现统计应用业务量
 原理：读取按照格式的yewu.sql，再将SQL分别查询并返回结果到列表，
       最后创建xlsx文件并写入列表结果

 yewu.sql格式：
 --系统
 --业务指标
 --数据库
 select count(1)/#day from dual
 where createdate > #starttime
 and createdate < #endtime
 --end
 依此类推
 '''
 reload(sys)
 sys.setdefaultencoding('gbk')
 username = ''
 password = ''
 epcis = ''
 epods = ''
 cxcc = ''
 nba4ot = ''
 claim = ''
 sqlfile = 'yewu.sql'
 day=''
 starttime = '2017-05-01'
 endtime = '2017-06-01'

 #格式化yewu.sql文件，按照系统、业务、数据库、SQL分割为一个二维列表
 def sql_file(sqlfile):
     a = open(sqlfile).read.split('--end')
     b = []
     for i in a:
         if i=='' or i =="\n\n":
             continue
         for j in  i.split('--'):
             b.append(j.strip()) #清理列表元素空格
     arr1 = []
     arr2 = []
     flag = 0
     for k in b:
         while flag >3: #创建有4个元素的arr2加入arr1列表
             arr1.append(arr2)
             #初始化arr2
             flag = 0
             arr2 = []
             print arr1
         else:
             if  k!='' and k!='\n\n' and k!='\n\n\n':
                 arr2.append(k)
                 flag += 1
     #替换列表里的#day、#starttime及#endtime
     for i in range(len(arr1)):
         arr1[i][3] = arr1[i][3].replace("#day",day)
         arr1[i][3] = arr1[i][3].replace("#starttime",starttime)
         arr1[i][3] = arr1[i][3].replace("#endtime", endtime)
     return arr1

 #查询二维列表的oracle SQL语句
 def oracle_select(db,sqlstr):
     listnew = ''
     sql = ''
     try:
         conn = oralce.connect(username,password,db)
         cur = conn.cusor()
         sql = cur.excecute(sqlstr)
     except Exception, e:
         print e.message
     else:
         listnew = sql.fetchone()
     cur.close()
     conn.close

 #查询没有mysql数据库的，果断pass哈
