Windows 64操作系统安装使用PL/SQL软件查询

下载好Instant Client Package并解压，在解压后的目录下新建network\admin\tnsnames.ora文件

tnsnames.ora文件内容：

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

mleo =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = TCP)
(HOST =192.168.1.115)
(PORT = 1521)
)
)
(CONNECT_DATA=
(sid=mleo)
)
)

设置PL/SQL中的连接的COI库，如图：



如果查询中文出现乱码，设置下编码格式，如图：

NLS_LANG
SIMPLIFIED CHINESE_CHINA.ZHS16GBK
