遠(yuǎn)程數(shù)據(jù)庫(kù)也是oracle嗎?那么你應(yīng)該配置tnsnames.ora,增加它。
describe
(address list
(Address (Protocol TCP) (Host 192.168.22.23) (Port 1521))
)
(connection _ data
(server-specific)
(Service Name Game World)

沒(méi)錯(cuò)。
oracle數(shù)據(jù)庫(kù)dblink怎么用?
在遠(yuǎn)程數(shù)據(jù)庫(kù)中創(chuàng)建dblink,然后使用
Insertintotable_name (column name 1, column name 2, ...) Select column name 1, column name 2,
能將Oracle數(shù)據(jù)導(dǎo)入sql server數(shù)據(jù)庫(kù)嗎?
Try using DBLink to connect to another library:-Create a database link Create a public database link name to connect to the user by password (description (address list (address (protocol TCP)) (host IP) (port port)) (connectionATA (service name sid)); You can use select × from TB name @DBLink_Name when using it.
Oracle實(shí)時(shí)同步Postgre如何實(shí)現(xiàn)?
數(shù)據(jù)庫(kù)a是主數(shù)據(jù)庫(kù)。。當(dāng)數(shù)據(jù)庫(kù)A中的數(shù)據(jù)被更新、刪除或添加時(shí)。使用觸發(fā)器在臨時(shí)表中記錄所有已更改的信息。然后數(shù)據(jù)庫(kù)BDBLINK到數(shù)據(jù)庫(kù)a,同時(shí)在DBLINK數(shù)據(jù)庫(kù)a的臨時(shí)表中建立觸發(fā)器,如果臨時(shí)表發(fā)生了變化。然后直接更新到數(shù)據(jù)庫(kù)b .這個(gè)數(shù)據(jù)庫(kù)同步步驟是我以前在一個(gè)系統(tǒng)里做的。我不 我不知道這對(duì)你是否有幫助。
