sql - 使用 DB_link 插入选择到远程数据库

Question

我正在尝试使用 DB_LINKS 更新远程数据库表，但出现错误

SQL Error: ORA-00907: missing right parenthesis
00907. 00000 -  "missing right parenthesis"
*Cause:    
*Action:

案例场景 -

从本地数据库- 以 sysdba 身份连接
```
sqlplus / as sysdba
```

使用从本地数据库获取的值更新远程数据库

INSERT INTO username.D_BackupStatus@db_link_name
(SELECT    ''''
    || (SELECT DECODE (db_unique_name, NULL, name, db_unique_name)
          FROM v$database)
    || ''','''
    || TO_CHAR (START_TIME, 'dd-mon-rr hh24:mi:ss')
    || ''','''

    AND input_type IN
           ('DB FULL', 'DB INCR')                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
           order      by   START_TIME);

输出

谁能帮我查询一下，有什么问题吗？？

从子查询中删除ORDER BY子句；在这种情况下它是无效的。

       AND input_type IN ('DB FULL', 'DB INCR')
       -- ORDER BY start_time
                                               );

不知道接下来会发生什么，除了您可以使用 q-quoting 机制并避免使用那么多单引号这一事实。
