LINUX下python 链接 oracle
打开链接下载oracle并解压
https://github.com/oracle/odpi
oracle_client
把解压的oracle文件放入/opt/oracle/目录下
操作步骤
sudo mkdir -p /opt/oracle
sudo mv instantclient_18_3 /opt/oracle/
cd /opt/oracle
sudo sh -c "echo /opt/oracle/instantclient_18_3 > /etc/ld.so.conf.d/oracle-instantclient.conf" #注意版本对应instantclient_18_3
sudo ldconfig
export LD_LIBRARY_PATH=/opt/oracle/instantclient_18_3:$LD_LIBRARY_PATH
mkdir -p /opt/oracle/instantclient_18_3/network/admin
下载libaio
sudo apt install libaio-dev

db_user ="trff_zjk"
db_passwd ="trff_zjk"
db_host ="192.168.50.10:1521"
# 数据库表名
table_name = 'WX_ZPXX_20181227_02'
# 数据库链接信息
conn_info = db_user+"/"+ db_passwd +"@"+ db_host +"/orcl"
conn=cx_Oracle.connect(conn_info)
#连接数据库
c=conn.cursor()
return c
