cx_Oracle使用

import cx_Oracle as orcl
print(orcl.clientversion())
username = "scott"
passwd = "123456"
host = "192.168.1.116"
port = "1521"
sid = "orcl"
dsn = orcl.makedsn(host, port,service_name= sid)
con = orcl.connect(username, passwd, dsn)
cursor = con.cursor()
sql = "SELECT ENAME, EMPNO FROM EMP"
cursor.execute(sql);
result = cursor.fetchall()
print("Total: " + str(cursor.rowcount))
for row in result:
    print(row)
 
cursor.close()
con.close()
print(orcl.Date(2015,3,13))

web2py中间件pydal使用

from gluon import DAL, Field
db = DAL('oracle://scott/[email protected]:1521/orcl')
db.define_table('dept',Field('DEPINO'),Field('DNAME'),Field('LOC'))
print db(db.test.DEPINO != "").select()

其他

创建数据库、创建数据表语句。

#表结构复制
create database link orcl CONNECT TO GW IDENTIFIED BY "******" USING 'R5DEV_223';  
CREATE TABLE testout.tab_users AS SELECT * FROM xyzdev.tab_users@orcl;  
create table testout.tab_users as select * from xyzdev.tab_users where 1=2
