Navicat Premium 连Oracle出错：ORA-12505, TNS:listener does not currently know of SID given in connect de

ORA-12505, TNS:listener does not currently know of SID given in connect descriptor 。


解决方法，使用sqlplus连接上oracle数据库之后，执行命令;


select INSTANCE_NAME from v$instance;

然后将显示的结果作为sid name填写到navicat相应的配置文件框内，再次进行连接即可。
