我需要提取mysql和db2的数据进行对比,所以需要用python对其都进行操作。
python对mysql进行操作应该没什么问题,就是安装drive后就可以了,在上一篇中有讲安装python-mysql的包即可。。。
python操作db2,我查了有两种方法,一个是DB2的包,一个是ibm_db的包,在我安装db2后,没有找到DB2的包,但是自动安装了ibm_db的包,所以我就选择了直接import ibm_db
这里附上一些ibm_db的操作方法 https://www-01.ibm.com/support/knowledgecenter/SSEPGG_9.5.0/com.ibm.db2.luw.apdv.python.doc/doc/r0054401.html
