SQL 开发人员连接
我正在尝试连接到 SQL Developer 中的数据库,以便可以开始练习 SQL。我应该与哪个数据库建立连接才能开始它是 10g Express 吗?
我尝试过创建一个新的连接;然而,我并没有成功。我不断收到错误消息:
“状态:故障测试失败:IO 错误:网络适配器无法建立连接”
我真的迷失了,我能找到的所有教程似乎都可以毫不费力地完成新的连接过程,而无需任何连接错误帮助;大多数信息似乎比我需要的基本设置帮助更高级。
谢谢。
附言。任何学习 SQL 的好的初学者资源将不胜感激。
I am trying to connect to a database in SQL Developer so I can start practising SQL. Which db should I create a connection with to begin is it 10g express?
I have tried creating a new connection; however, I have not been successful. I keep getting the error message:
"Status : Failure-Test failed: IO Error: The Network Adapter could not establish the connection"
I am really lost, all the tutorials I can find seem to move through the new connection process effortlessly without any connection error help; most of the information seems to be more advanced than the basic setup help I need.
Thanks.
PS. any good beginner resources for learning SQL would be much appreciated.
