在SQL Server 2008中，如何查询具有指向特定表列的外键引用的表?

In MSSQL 2008 how can I query for tables with foreign key references to a specific table column?

在MSSQL 2008中，如何查询具有指向特定表列的外键引用的表?

Let's say I have a table called Audit with an int column called 'ID". How can I find all the tables in my database that have a foreign key to Audit.ID ?

假设我有一个名为Audit的表，它的int列名为“ID”。如何在数据库中找到所有需要审计的外键的表。ID吗?
