SQL脚本查找特定表的外键？

Question

是否有一个查询可以获取针对特定表列的外键？例如,假设我有这三个表:

__________
|Table A |
----------
|Id      |
----------

___________
|Table B  |
-----------
|Id       |
|TableAId | (Foreign Key to TableA.Id)
-----------

___________
|Table C  |
-----------
|Id       |
|TableAId | (Foreign Key to TableA.Id)
-----------

我需要一个查询"Select*外键指向TableA.Id",返回"表C:TableAId","表B:TableAId".我正在浏览一些INFORMATION_SCHEMA系统视图,看起来我可以很容易地看到外键分别属于表A或表B,但我找不到它所说的"表C有一个外键到表A"具体而言.我可以弄清楚查询的细节,我只是找不到我正在寻找的视图(或者我正在掩饰它们).任何帮助,将不胜感激.

由Pinal Dave提供:

SELECT 
    f.name AS ForeignKey,
    OBJECT_NAME(f.parent_object_id) AS TableName,
    COL_NAME(fc.parent_object_id,
    fc.parent_column_id) AS ColumnName,
    OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
    COL_NAME(fc.referenced_object_id,
    fc.referenced_column_id) AS ReferenceColumnName
FROM 
    sys.foreign_keys AS f
    INNER JOIN sys.foreign_key_columns AS fc ON f.OBJECT_ID = fc.constraint_object_id
