小記：
首先建立數(shù)據(jù)庫(kù)連接：
-- Drop existing database link
drop public database link DB4960;
-- Create database link
create public database link DB4960
connect to ctile identified by ctile
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.11.41.60)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)';
然后需要建立同義詞：
create public synonym mistel.table for
mistel.table@DB4960;
然后就可以在本地使用select * from mistel.table 查詢DB4960上的數(shù)據(jù)庫(kù)表。
