Database：PLSQL连接Oracle数据库（两种方式）

1、直接连接方式

2、配置文件方式

# 注意开头不能有空格
# 本地数据库 localhost
locDB =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = orcl)
   )
 )

# 网上数据库 192.168.0.103
aliDB =
(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.103)(PORT = 1521))
  (CONNECT_DATA =
   (SERVER = DEDICATED)
   (SERVICE_NAME = orcl)
  )
)
