如何通过python连接到Oracle DB

Question

我正在尝试通过Python连接到Oracle并尝试执行一些DDL＆amp; DML语句。请帮助它如何完成

Answer 1

一个简单的查询

import cx_Oracle
con = cx_Oracle.connect('pythonhol/welcome@127.0.0.1/orcl')
cur = con.cursor()
cur.execute('select * from departments order by department_id')
for result in cur:
    print result
cur.close()
con.close()     

Answer 2

您可以这样做：

import cx_Oracle
connection = cx_Oracle.connect("username", "password", "ip of your server"/"database name")

cursor = connection.cursor()
cursor.execute("select * from table_name")

for row in cursor:
    print(row)
connection.close()
