有些時候我們需要和程序交互，此時需要綁定量
下面兩個例子簡介在SELECT 和 DML 里面綁定變量的用法

SELECT 里面的綁定變量

?

    
      [root@Ora10G py]# cat SelectBinding.py

#!/bin/env python

#coding=utf-8

#filename:execise binding in select

import cx_Oracle



conn=cx_Oracle.connect('hr/hr@orcl')

cur=conn.cursor()



dept_id=raw_input('\n please input department ID you want to search:')

dept_name=raw_input(' please input department name you want to seaarch:')



cur.execute('''select * from departments

                where department_id=:id and

                      department_name=:name

            ''',id=dept_id,name=dept_name

            )



rows=cur.fetchall()

print '\ninformation are as following:'

for row in rows:

  print row



cur.close()

conn.close()

DML 里面的綁定變量

      [root@Ora10G py]# cat DmlBinding.py

#!/bin/env python

#coding=utf-8

#filename:execise binding in dml

#Author:DBA_WaterBin



import cx_Oracle



conn=cx_Oracle.connect('hr/hr@orcl')

cur=conn.cursor()





cur.execute('''insert into departments (department_id,department_name,manager_id,location_id) 

               values(:ID,:NAME,:MGR_ID,:LOC_ID)

              ''', {'ID':555,'NAME':'WaterBin','MGR_ID':110,'LOC_ID':7788}

           )

cur.close()

conn.commit()

conn.close()
