python 记一次将数据库查询结果写入到表格经历



说明:

    运营那边提了一些需求,在开发还没有在页面上实现此功能前,每天早上都要我们查询sql语句做成表格,然后发给他们,感觉好烦啊,就用python写了一个脚本,实现此功能



第一次尝试:

分析:

    因为有多个sql查询语句,然后制作成多个表格,所以写了多个函数,将每个sql语句分别写到每个函数里

    而且表格的列名也是需要手动输入的,感觉好麻烦,而且好傻瓜





第二次尝试:

#!/usr/bin/env python
#encoding=UTF-8

import MySQLdb
import xlwt    #excel write

hostIp = '10.10.94.157'
user = 'xxx'
passwd = 'xxxx'

reSql = f.read().split(';')                  #将所有的sql语句赋值给reSql; select.sql文件里的sql语句要以';'结尾
f.close()

def chongZhiWeiTouZi():                      #充值未投资用户
    style1= xlwt.XFStyle()                   #设置单元格格式
    style1.num_format_str= 'yyyy/m/d h:mm:ss'

    wb=xlwt.Workbook(encoding='utf-8')       #创建一个excel工作簿,编码utf-8,表格中支持中文
    sheet=wb.add_sheet('sheet 1')            #创建一个sheet

    db = MySQLdb.connect(hostIp,user,passwd,database,charset="utf8")         #连接数据库,编码utf-8
    cursor = db.cursor(cursorclass = MySQLdb.cursors.DictCursor)             #创建一个指针对象
    cursor.execute(reSql[0])                 #执行sql语句
    results = cursor.fetchall()

    columnName = []
    for i in results[0].keys():
        columnName.append(i)

    columnLen = len(columnName)
    for i in range(columnLen):               #将列名插入表格,共6列
        sheet.write(0,i,columnName[i])

    rows = len(results)                      #获取行数

    for i in range(rows):
        for j in range(columnLen):
            sheet.write(i+1,j,results[i][columnName[j]])

    wb.save('员工信息表.xls')                #保存表格,并命名为 员工信息表.xls
    cursor.close()
    db.close()

def yongHuDengLu():          #用户登录信息
    style1= xlwt.XFStyle()                   #设置单元格格式
    style1.num_format_str= 'yyyy/m/d h:mm:ss'

    wb=xlwt.Workbook(encoding='utf-8')       #创建一个excel工作簿,编码utf-8,表格中支持中文

    columnLen = len(columnName)

分析:

注意:每个sql语句要以‘;’结尾

vim select.sql

SELECT
ctci.acc_no AS '账号',
ctci.cn_name AS '姓名',
ctci.job_phone AS '手机',
ctci.create_date AS '注册时间',
        tta.amount AS '充值金额',
        tta.create_time AS '充值时间'
FROM
        TPP_T_ACCOUNT_DEAL tta,CRM_T_CUSTOMER_INFO ctci
WHERE
        tta.customer_id = ctci.id AND
        tta.type = 1
AND tta.order_status IN (1, 9)
AND tta.customer_id NOT IN (
SELECT DISTINCT customer_id FROM J_P2P_ORDER WHERE order_type = 1 and product_id !=1
);

select a.acc_no as '用户名',a.cn_name as '姓名',a.mobile as '银行预留手机',a.job_phone as '登录手机',b.order_amount as '投资金额',
c.name as '产品' ,b.lucky_numbers as '幸运号'
from ACTIVITY_LUCKY_NUMBER b left join CRM_T_CUSTOMER_INFO a on b.customer_id = a.id
left join J_P2P_PRODUCT c on b.product_id = c.id
where  b.period='4';



    而且表格的列名会自己从查询结果里获取,不再手动输入

    不过,感觉还是很乱,很复杂,而且依然用了多个函数,而且最终的表格格式还不好看,如下:

python查询mysql后批量插入clickhouse python 查询数据库表_数据库





第三次尝试:

    这次没有再用MySQLdb模块


#!/usr/bin/env python
#encoding=UTF-8

import os
import xlwt    #excel write

hostIp = '10.10.94.157'
user = 'xxxx'
passwd = 'xxxx'
db = 'xxxx'

f = open('select.sql','r')
reSql = f.read().split(';')                  #将所有的sql语句赋值给reSql; select.sql文件里的sql语句要以';'结尾
f.close()

def createTable(selectSql,tableName): 
    results = os.popen('mysql -h'+hostIp+' -u'+user+' -p'+passwd+' -D'+db+' -e "'+selectSql+'"').read().strip().split('\n')
    columnName = results[0].split('\t')


    wb=xlwt.Workbook(encoding='utf-8')       #创建一个excel工作簿,编码utf-8,表格中支持中文
    sheet=wb.add_sheet('sheet 1')            #创建一个sheet

    rows = len(results)                      #获取行数
    columns = len(columnName)

    for i in range(rows):
        for j in range(columns):
            sheet.write(i,j,results[i].split('\t')[j])

    wb.save(tableName)                       #保存表格
    
createTable(reSql[0],'充值未投资用户.xls')
createTable(reSql[1],'活动投资名单.xls')



分析:

    这次感觉还不错,只写了一个函数,语句看上去没有那么复杂

    所有的sql语句同样写到select.sql文件里,且以‘;’结尾


vim select.sql

SELECT
ctci.acc_no AS '账号',
ctci.cn_name AS '姓名',
ctci.job_phone AS '手机',
ctci.create_date AS '注册时间',
        tta.amount AS '充值金额',
        tta.create_time AS '充值时间'
FROM
        TPP_T_ACCOUNT_DEAL tta,CRM_T_CUSTOMER_INFO ctci
WHERE
        tta.customer_id = ctci.id AND
        tta.type = 1
AND tta.order_status IN (1, 9)
AND tta.customer_id NOT IN (
SELECT DISTINCT customer_id FROM J_P2P_ORDER WHERE order_type = 1 and product_id !=1
);

select a.acc_no as '用户名',a.cn_name as '姓名',a.mobile as '银行预留手机',a.job_phone as '登录手机',b.order_amount as '投资金额',
c.name as '产品' ,b.lucky_numbers as '幸运号'
from ACTIVITY_LUCKY_NUMBER b left join CRM_T_CUSTOMER_INFO a on b.customer_id = a.id
left join J_P2P_PRODUCT c on b.product_id = c.id
where  b.period='4';



    这次表格样式如下:

python查询mysql后批量插入clickhouse python 查询数据库表_sql_02

    表格格式感觉还是不好看





最终优化:

    这次优化了表格的输出格式(列名加粗,列的宽度,居中,字体等)

    优化了select.sql文件:里面可以写以“#”开头的注释(仍要以“;”结尾)

vim select.sql

#充值未投资用户#
SELECT
ctci.acc_no AS '账号',
ctci.cn_name AS '姓名',
ctci.job_phone AS '手机',
ctci.create_date AS '注册时间',
        tta.amount AS '充值金额',
        tta.create_time AS '充值时间'
FROM
        TPP_T_ACCOUNT_DEAL tta,CRM_T_CUSTOMER_INFO ctci
WHERE
        tta.customer_id = ctci.id AND
        tta.type = 1
AND tta.order_status IN (1, 9)
AND tta.customer_id NOT IN (
SELECT DISTINCT customer_id FROM J_P2P_ORDER WHERE order_type = 1 and product_id !=1
);


#活动投资名单
select a.acc_no as '用户名',a.cn_name as '姓名',a.mobile as '银行预留手机',a.job_phone as '登录手机',b.order_amount as '投资金额',
c.name as '产品' ,b.lucky_numbers as '幸运号'
from ACTIVITY_LUCKY_NUMBER b left join CRM_T_CUSTOMER_INFO a on b.customer_id = a.id
left join J_P2P_PRODUCT c on b.product_id = c.id
where  b.period='4';

#!/usr/bin/env python
#encoding=UTF-8

import os
import time
import xlwt                                  #excel write

sqlStr = ''
for i in open('select.sql','r').readlines():
    if i.startswith('#') == True:            #忽略掉#号开头的行
        pass
    else:
        sqlStr = sqlStr + i
reSql = sqlStr.split(';')                    #将所有的sql语句赋值给reSql; select.sql文件里的sql语句要以';'结尾

def createTable(selectSql,tableName):

    rows = len(results)                      #获取行数
    columns = len(columnName)

    style = xlwt.XFStyle()                   #创建格式style
    font = xlwt.Font()                       #创建font,设置字体
    font.name = 'Times New Roman'            #字体格式
    style.font = font                        #将字体font,应用到格式style
    alignment = xlwt.Alignment()             #创建alignment,居中
    alignment.horz = xlwt.Alignment.HORZ_CENTER      #居中
    style.alignment = alignment              #应用到格式style

    style1 = xlwt.XFStyle()
    font1 = xlwt.Font()
    font1.name = 'Times New Roman'
    #font1.colour_index = 3                  #字体颜色(绿色)
    font1.bold = True                        #字体加粗
    style1.font = font1
    style1.alignment = alignment

    for i in range(columns):
        sheet.col(i).width = 5000            #设置列的宽度

    for i in range(columns):
        sheet.write(0,i,columnName[i],style1)     #将数据插入表格

    for i in range(1,rows):
        for j in range(columns):
            sheet.write(i,j,results[i].split('\t')[j],style)
            #sheet.write(i,j,results[i].split('\t')[j])

    wb.save(tableName)                       #保存表格,并命名为 充值未投资用户.xls

excelTime = time.strftime("%Y%m%d")          #获取当前时间

createTable(reSql[0],excelTime+'充值未投资用户.xls')
createTable(reSql[1],excelTime+'活动投资名单.xls')



    最终表格格式如下:

python查询mysql后批量插入clickhouse python 查询数据库表_sql语句_03

    是不是很完美!!
