python 读写Oracle10g数据简介

1、测试环境:

Centos6 X86_64
python 2.6
Oracle 10g

2、安装cx_Oracle 和 Oracle InstantClient:

http://www.rpmfind.net/linux/rpm2html/search.php?query=cx_oracle
http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

3、编辑当前用户的 .bash_profile, 在文件末尾增加下行:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/oracle/10.2.0.3/client64/lib

命令行执行 source .bash_profile

4、现在就可以用 python 脚本非常轻松的读写Oracle数据库

数据查询示范脚本 select_ora.py

# This script prints the data in Oracle Sample table scott.emp .# Run with a parameter ‘PageSize‘ in integer form, the output pauses at the end of every page.# Run without a parameter or the parameter is not in integer form, the output doesn‘t pasue.# Like: 
# $ python select_ora.py 30
# $ python select_ora.py
#
import sysimport cx_Oracletry: intPageSize = int(sys.argv[1])except: intPageSize = -1 #print "Please input an integer." #quit() conn = cx_Oracle.connect(scott/tiger@192.168.150.115/c6115‘)cursor = conn.cursor ()cursor.execute ("select * from emp")print "EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO"print "========================================================"while (1): row = cursor.fetchone() if row == None: break print "%d, %s, %s, %s, %s, %s, %s, %s" % (row[0], row[1], row[2], row[3], row[4],row[5],row[6],row[7]) if intPageSize <> -1 and cursor.rowcount % intPageSize == 0 : strPress = raw_input( "Row: %d" % cursor.rowcount + ". Press Enter to continue, q to quit..." ) if strPress == q: break print "Number of rows returned: %d" % cursor.rowcountcursor.close ()conn.close ()

 

数据插入示范脚本 insert_ora.py

import cx_OraclestartNum = raw_input("Start Num:")endNum = raw_input("End Num:") conn = cx_Oracle.connect(scott/tiger@192.168.150.115/c6115)cursor = conn.cursor()i = int(startNum)while (1):    i = i+1    if i > int(endNum):        break     theNum=str(i)    cursor.execute("insert into emp (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO) values("+theNum+",‘FORD"+theNum+"‘,‘CLERK‘,7782,‘09-JUN-81‘,2500,0,30)")    conn.commit()    print "Line "+ theNum +" inserted."cursor.close()conn.close()
