sql-server-2012 - 查找所有相关表

Question

我有一个包含大约 1000 个表的数据库，我需要找到与特定表相关的所有表，比如说客户表。我该如何进行？

Answer 1

当您要求查找与特定表相关的所有表时，我假设您要查找所有具有对“客户”表的外键引用的表。这与之前的 Stack Overflow 问题密切相关。以下使用系统目录视图的查询应该可以解决问题：

select t.name as TableWithForeignKey, fk.constraint_column_id as FK_columns , c.name as ForeignKeyColumn 
    from sys.foreign_key_columns as fk
        inner join sys.tables as t on fk.parent_object_id = t.object_id
        inner join sys.columns as c on fk.parent_object_id = c.object_id and fk.parent_column_id = c.column_id
    where fk.referenced_object_id = (select object_id from sys.tables where name = 'customers')
    order by TableWithForeignKey, ForeignKeyColumn
