ORA-02019 connection description for remote database not found Cause: An attempt was made to connect or log in to a remote database using a connection description that could not be found. Action: Specify an existing database link. Query the data dictionary to see all existing database links. See your operating system-specific Net8 documentation for valid connection descriptors. 检查所用到DBLINK名是否已经定义
第一:数据库多链是肯定允许的。你要检查DBLINK名的存在与否性。第二:编程方式不好,INSERT INTO TAB A 时最好把 A的要插入的字段名加上。若哪天A表加了一个字段,扩展了一下,这SQL就要报错了。
