話不多說，直接上代碼。

"""

一、安裝環境：

python3

pip install pymysql

pip install pymssql

二、實現功能：

將mysql的oa_2016.formmain_5027(手機打卡記錄)數據，增量同步到sqlserver數據庫的kaoqin.CHECKINOUT中

三、運行方法：

a)定時任務

[root@oadb1 shell]# crontab -l

* * * * * python -W ignore /usr/local/shell/sync_mobile_kaoqin.py >> /var/log/sync_mobile_kaoqin.log 2>&1

b) 日志位置

tail -f /var/log/sync_mobile_kaoqin.log

四、測試sql：

mysql執行

select * from oa_2016.formmain_5027

sqlserver上執行

select * from CHECKINOUT where sn='手機端打卡'
