查找所有相關的表

Question

我有一個大約有1000個表的數據庫，我需要找到與特定表相關的所有表，比如說客戶表。我如何繼續？

Answer 1

當您要求查找與特定表相關的所有表時，我假設您要求所有具有對「客戶」表的外鍵引用的表。這與previous Stack Overflow question密切相關。使用該系統目錄視圖下面的查詢應該做的伎倆：

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
