有没有一个查询会让我指向特定表列的外键？例如，说我有这三个表：
- __________
- |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“Select * Foreign Keys directed to TableA.Id”的返回“Table C：TableAId”，“Table B：TableAId”的查询。我正在浏览一些INFORMATION_SCHEMA系统视图，似乎我可以轻松地看到外键属于表A或表B，但我找不到它所在的位置“表C有一个外键表A“具体。我可以弄清楚查询的细节，我找不到我正在寻找的视图(或者我正在掩饰他们)。任何帮助将不胜感激。
解决方法

- 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
