sql-server - 我可以在 SQL Server 中找到视图的外键关系吗？

Question

我已经构建了一个使用表外键的工具，但我想扩展它以支持视图。

在 SQL Server 2008 及更高版本中，假设您只对同一数据库中的依赖项感兴趣，您可以使用以下查询来确定每个视图中引用的所有表、视图和函数：

;WITH x AS
(
 SELECT
  v = QUOTENAME(OBJECT_SCHEMA_NAME(d.referencing_id))
     + '.' + QUOTENAME(OBJECT_NAME(d.referencing_id)),
  t = QUOTENAME(OBJECT_SCHEMA_NAME(d.referenced_id))
     + '.' + QUOTENAME(OBJECT_NAME(d.referenced_id)),
  td = o2.type_desc
 FROM sys.sql_expression_dependencies AS d
 INNER JOIN sys.objects AS o1
 ON d.referencing_id = o1.[object_id]
 INNER JOIN sys.objects AS o2
 ON d.referenced_id = o2.[object_id]
 WHERE o1.type_desc = 'VIEW'
)
SELECT [View] = v, Referenced_Object = t, [Type] = td
 FROM x
 GROUP BY v, t, td
 ORDER BY v, t;
