这个VIEW 在创建时， exchbankbizoperatorlog2，明明使用了远程表 EXCHBANKBIZOPERATORLOG, his_EXCHBANKBIZOPERATORLOG为何视图没查询到？
SQL> create or replace view exchbankbizoperatorlog2 as
select * from EXCHBANKBIZOPERATORLOG@link_bank where ExchID = 106
union all
select * from his_EXCHBANKBIZOPERATORLOG@link_bank where ExchID = 106;234
View created.
SQL> select * from dba_dependencies where name=upper('EXCHBANKBIZOPERATORLOG2');
no rows selected
SQL> select * from v$version;
