Question

在Oracle SQL开发人员GUI中，我打开了一个表，并显示了一个带有属性的窗口。这是一个名为Dependencies的窗口选项卡。

我找到了这个查询：

select    OWNER
        , name
        , type
        , referenced_name
        , referenced_type
  from all_dependencies;

但是没有像Oracle SQL Developer那样为所有所有者显示输出。

如何通过与所有所有者的查询SQL获取这些结果？

谢谢！

使用如下查询：

select owner, name, type, referenced_owner, referenced_name, referenced_type
from dba_dependencies
where referenced_owner = user and referenced_name = 'YOUR_TABLE_NAME';

或使用绑定变量：

var object_owner varchar2(30);
var object_name varchar2(30);
exec :object_owner := user;
exec :object_name := 'YOUR_TABLE_NAME';

select owner, name, type, referenced_owner, referenced_name, referenced_type
from dba_dependencies
where referenced_owner = :object_owner and referenced_name = :object_name ;

您实际上可以看到SQL Developer在后台运行的查询。如果你转到视图菜单并选择日志，或点击 Ctrl Shift L （假设你正在使用Windows）你＆＃ 39; ll得到一个停靠窗口，默认标题为＆＃34; Messages - Log＆＃34;。在底部是两个标签，其中包含＆＃34;消息＆＃34;选择。如果您点击＆＃34;语句＆＃34;相反，你可以看到使用的语句和绑定变量。

在这种情况下，刷新依赖项选项卡时会发出三个语句，其中两个是我上面显示的内容的变体 - 它们会获得更多列，并检查两种方式的依赖关系：

select owner, name, type, referenced_owner, referenced_name, referenced_type ,
  owner sdev_link_owner, name sdev_link_name, type sdev_link_type
from Dba_DEPENDENCIES
where referenced_owner = :OBJECT_OWNER and referenced_name = :OBJECT_NAME

select owner, name, type, referenced_owner, referenced_name, referenced_type ,
  referenced_owner sdev_link_owner, referenced_name sdev_link_name, referenced_type sdev_link_type
from Dba_DEPENDENCIES
where owner = :OBJECT_OWNER and name = :OBJECT_NAME

如果你想弄清楚你能看到什么，那么它们是一个很好的起点。

如果您作为没有查看dba_dependencies表所需权限的用户进行连接，则SQL Developer会返回all_dependencies：

select owner, name, type, referenced_owner, referenced_name, referenced_type ,
  owner sdev_link_owner, name sdev_link_name, type sdev_link_type
from ALL_DEPENDENCIES
where referenced_owner = :OBJECT_OWNER and referenced_name = :OBJECT_NAME

select owner, name, type, referenced_owner, referenced_name, referenced_type ,
  referenced_owner sdev_link_owner, referenced_name sdev_link_name, referenced_type sdev_link_type
from Dba_DEPENDENCIES
where owner = :OBJECT_OWNER and name = :OBJECT_NAME

仅显示有关您具有选择/执行权限的对象的信息。在上面显示的第一个查询中，您只需将dba_dependencies更改为all_dependencies即可查看等效（可见）结果。

如果您以与SQL Developer相同的用户手动运行SQL，则会看到相同的结果。
