docker--在Anaconda jupyter 容器中使用oracle数据源时，Oracle客户端安装配置及使用示例

enjoy编程2023-10-13 23:08

配置oracle 11.2 客户端

将instantclient-basic-linux.x64-11.2.0.4.0.zip解压至/home/jupyter/oracle/
将instantclient-sqlplus-linux.x64-11.2.0.4.0.zip解压/home/jupyter/oracle/【可选，提供sqlplus命令】
复制【操作系统一般都有安装libaio.so】 cp /usr/lib64/libaio.so.1 /home/jupyter/oracle/instantclient_11_2/
ln -s /home/jupyter/oracle/instantclient_11_2/libclntsh.so.11.1 /home/jupyter/oracle/instantclient_11_2/libclntsh.so

bash 复制代码

docker run -d --rm --name=jupyter-server -p 8888:8888 \
	-e  LD_LIBRARY_PATH=/home/oracle/client:$LD_LIBRARY_PATH 
	-v /home/jupyter/notebook:/root/jupyter:rw 
	-v /home/jupyter/oracle/instantclient_11_2:/home/oracle/client 
	-v /home/jupyter/assets:/opt/conda/lib/python3.9/site-packages/notebook/static/components/pyecharts/assets:ro jupyter:2023.8.23

在jupyter中使用示例

导入依赖m

python 复制代码

import cx_Oracle
import pandas as pd
import os
from sqlalchemy import create_engine
os.environ['NLS_LANG']='SIMPLIFIED CHINESE_CHINA.UTF8'
from sqlalchemy import text

使用cursor方式

python 复制代码

conn = cx_Oracle.connect('user/[email protected]:1521/orcl')
cursor=conn.cursor()
cursor.execute("select * from USER ")
cursor.fetchall()[0]

pandas方式

原生连接方式

python 复制代码

df=pd.read_sql("select * from USER where IS_STATUS=:status",conn,params={'status':2})
df

使用sqlalchemy方式

python 复制代码

engine = create_engine("oracle+cx_oracle://user:[email protected]:1521/orcl",echo=False)
conn = engine.connect()
df=pd.read_sql_query(text("select * from USER where IS_STATUS=1"),con=conn)
df

碰到的坑

报 'OptionEngine' object has no attribute 'execute'错误
报Not an executable object:
