如果要连接到 Oracle 数据库 11.2,则需要通过在代码中调用oracledb.init_oracle_client()来启用厚模式。 请参阅用户文档https://python-oracledb.readthedocs.io/en/latest/user_guide/initialization.html#enabling-python-oracledb-thick-mode 我是这样做的: 检查我要连接的oracle数据库版本: 因为是企业的正式数据...
Previously, new instances were created for each call in Thick mode. Common Changes Added support for Python 3.13 and dropped support for Python 3.7. Attribute :data:`ConnectionPool.getmode` is now one of the values of the enumeration :ref:`connection pool get modes <connpoolmodes>` in order...
Thin mode: By default python-oracledb runs in a 'Thin' mode which connects directly to Oracle Database. Thick mode: Some advanced Oracle Database functionality is currently only available when optional Oracle Client libraries are loaded by python-oracledb. Libraries are available in the freeOracle...
thick_mode=True ) 3. 应用案例和最佳实践 应用案例 数据分析:使用python-oracledb从 Oracle 数据库中提取数据,进行数据分析和可视化。 Web 应用:在 Web 应用中使用python-oracledb连接到 Oracle 数据库,进行数据存储和检索。 ETL 流程:在 ETL(Extract, Transform, Load)流程中,使用python-oracledb从 Oracle 数据...
ただし、python-oracledbはOracle Clientと共に使用することも可能です。Thin Mode(Oracle Client不使用)とThick Mode(Oracle Client使用)の両対応となります。Oracle Clientが必要になる(Thick Modeが必要になる)のは以下のケースです。 Oracle Client 11gを使用する場合。12c以降のOracle ClientはThin Modeで...
I am using python-oracledb Thin mode and trying to connect to a database where the sqlnet.ora file is as under: SQLNET.ENCRYPTION_SERVER=REQUIRED SQLNET.CRYPTO_CHECKSUM_SERVER=REQUIRED SQLNET.ENCRYPTION_TYPES_SERVER=(AES256,AES192,AES128) ...
oracledb.exceptions.NotSupportedError: DPY-3010: connections to this database server version are not supported by python-oracledb in thin mode
If I setconnection.stmtcachesize = 0and run again in Thick mode there is no issue. This is really a DB issue outside the scope of python-oracledb, though we have tried to work around it, and have got some DB side improvements made in various scenarios ...
does not work regardless if it is thin or thick mode. Include a runnable Python script that shows the problem. import pyodbc cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=SQLSRV01;DATABASE=DATABASE;UID=USER;PWD=PASSWORD') cursor = cnxn.cursor() cursor.execute("SELECT 1, 2 UNION SEL...
