from sqlalchemy import create_engine

import cx_Oracle

#db=cx_Oracle.connect('admin','admin','172.16.1.452:1521/orcl',encoding = "UTF-8", nencoding = "UTF-8")
db=cx_Oracle.connect('你的賬號','密碼','IP:端口/服務名',encoding = "UTF-8", nencoding = "UTF-8")
print (db.version)

cr=db.cursor()

SQL2 = '''SELECT * FROM OA_W_BAOXIAOMXYWB'''

cr.execute(SQL1)

rs=cr.fetchall()

zz=pd.DataFrame(rs)

print (zz)

db.close()
