java语句：
Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521: PLSExtProc","zwl","zwl");
System.out.println("连接成功！");

tnsnames.ora文件
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
本来SID是ORAL，可是用ORAL也是报错，求解

Answer 1

这个是SQLException，确认是连接的哪个数据库，如果数据库对的话，就看一下SQL取数语句了。

Answer 2

我记得是orcl吧
