SQL Server查找一个外键被引用的所有表

直接上代码：

SELECT  oSub.name AS [子表名称] ,
        fk.name AS [外键名称] ,
        SubCol.name AS [子表列名] ,
        oMain.name AS [主表名称] ,
        MainCol.name AS [主表列名]
FROM    sys.foreign_keys fk
        JOIN sys.all_objects oSub ON ( fk.parent_object_id = oSub.object_id )
        JOIN sys.all_objects oMain ON ( fk.referenced_object_id = oMain.object_id )
        JOIN sys.foreign_key_columns fkCols ON ( fk.object_id = fkCols.constraint_object_id )
        JOIN sys.columns SubCol ON ( oSub.object_id = SubCol.object_id
                                     AND fkCols.parent_column_id = SubCol.column_id
                                   )
        JOIN sys.columns MainCol ON ( oMain.object_id = MainCol.object_id
                                      AND fkCols.referenced_column_id = MainCol.column_id
                                    )
WHERE   fk.name LIKE @FOREIGN KEY;

@FOREIGN KEY :外键键名
