更改 <class 'cx_Oracle.Cursor'> 在python中列出或命令

Question

I am working on a code to fetch data from a server and then plot two column of data in python. I am using cx_Oracle library and I could fetch data.

But as I checked type of fetched data is class 'cx_Oracle.Cursor' .

How can I change data type to list or dictionary :

import cx_Oracle

conn_str = u'user/pass@IP1:1521/STAT4P'
conn = cx_Oracle.connect(conn_str)
c = conn.cursor()
sql='''select ne,sdate,slot_no,subrack_no,ID_73393960 as HIII,ID_73410486 from Huawei_wcdma.UDSP60 where ne=:name'''

# c.execute(u'select ne,sdate,slot_no,subrack_no,ID_73393960,ID_73410486 from Huawei_wcdma.UDSP60')
c.execute(sql,name="AQRNCH01")
print(type(c))

I want to plot sdate vs. ID_73393960 , but how ?

In your code "c" is the cursor... it is NOT your data. you need to pull the data out using a fetch command. This is an example from the cx_oracle tutorial using fetchone()-

https://github.com/oracle/python-cx_Oracle/tree/master/samples/tutorial (Try the tutorial to learn the rest of the methods on the cursor object)

import cx_Oracle

con = cx_Oracle.connect("pythonhol", "welcome", "localhost/orclpdb")
cur = con.cursor()

cur.execute("select * from dept order by deptno")
row = cur.fetchone()
print(row)

row = cur.fetchone()
print(row)
