ERROR: ORA-03121: no interface driver connected - function not performed用PL/SQL可以正常连接到oracle服务器请问这是什么问题？谢谢！
Cause: This message occurs usually because the Net8 driver is not loaded into memory or there is a mismatch of the version of the driver. A user program linked with an obsolete library may also cause this message. Only programs provided by Oracle Corporation should use this interface.
Action: If the message occurred during use of a program provided by Oracle Corporation, contact Oracle Support Services. If a user program caused the message, relink the program with current versions of the Oracle libraries.
