要将其作为扩展添加到SQL Developer，请执行以下操作:

将下面的代码保存到一个xml文件(例如fk_ref.xml):

<items>
    <item type="editor" node="TableNode" vertical="true">
    <title><![CDATA[FK References]]></title>
    <query>
        <sql>
            <![CDATA[select a.owner,
                            a.table_name,
                            a.constraint_name,
                            a.status
                     from   all_constraints a
                     where  a.constraint_type = 'R'
                            and exists(
                               select 1
                               from   all_constraints
                               where  constraint_name=a.r_constraint_name
                                      and constraint_type in ('P', 'U')
                                      and table_name = :OBJECT_NAME
                                      and owner = :OBJECT_OWNER)
                               order by table_name, constraint_name]]>
        </sql>
    </query>
    </item>
</items>

将扩展添加到SQL Developer: 工具>首选项 数据库>用户定义扩展 点击“添加行”按钮 在类型中选择“编辑器”，位置是你上面保存xml文件的位置 单击“确定”，然后重新启动SQL Developer 导航到任何表，您现在应该在SQL表旁边看到一个附加选项卡，标记为FK References，其中显示新的FK信息。 参考 http://www.oracle.com/technetwork/issue-archive/2007/07-jul/o47sql-086233.html

为sql developer插件添加上面的答案，使用下面的xml将有助于获得与外键相关的列。

    <items>
        <item type="editor" node="TableNode" vertical="true">
        <title><![CDATA[FK References]]></title>
        <query>
            <sql>
                <![CDATA[select a.owner,
                                a.constraint_name,
                                a.table_name,
                                b.column_name,
                                a.status
                         from   all_constraints a
                         join   all_cons_columns b ON b.constraint_name = a.constraint_name
                         where  a.constraint_type = 'R'
                                and exists(
                                   select 1
                                   from   all_constraints
                                   where  constraint_name=a.r_constraint_name
                                          and constraint_type in ('P', 'U')
                                          and table_name = :OBJECT_NAME
                                          and owner = :OBJECT_OWNER)
                                   order by table_name, constraint_name]]>
            </sql>
        </query>
        </item>
    </items>

你可以从ALL_CONSTRAINTS视图中查询:

SELECT table_name
FROM ALL_CONSTRAINTS
WHERE constraint_type = 'R' -- "Referential integrity"
  AND r_constraint_name IN
    ( SELECT constraint_name
      FROM ALL_CONSTRAINTS
      WHERE table_name = 'EMP'
        AND constraint_type IN ('U', 'P') -- "Unique" or "Primary key"
    );

仅用主表名替换table_name

select *
from all_constraints
where r_constraint_name in (
select constraint_name
from all_constraints
where table_name='table_name'
); 

这已经在产品中存在多年了——尽管在2011年的产品中还没有。

但是，只需单击Model页面。

请确保您使用的版本至少为4.0(2013年发布)才能访问此功能。

我喜欢使用直接的SQL查询来实现这一点，而不是在SQL Developer应用程序中瞎折腾。

我是这么做的。最好通读这篇文章，了解发生了什么，这样你就可以调整它来满足你的需求……

WITH all_primary_keys AS (
  SELECT constraint_name AS pk_name,
         table_name
    FROM all_constraints
   WHERE owner = USER
     AND constraint_type = 'P'
)
  SELECT ac.table_name || ' table has a foreign key called ' || upper(ac.constraint_name)
         || ' which references the primary key ' || upper(ac.r_constraint_name) || ' on table ' || apk.table_name AS foreign_keys
    FROM all_constraints ac
         LEFT JOIN all_primary_keys apk
                ON ac.r_constraint_name = apk.pk_name
   WHERE ac.owner = USER
     AND ac.constraint_type = 'R'
     AND ac.table_name = nvl(upper(:table_name), ac.table_name)
ORDER BY ac.table_name, ac.constraint_name
;
