我正在阅读关于如何根据 m_indexId 计算分配单元 ID的文章http://www.sqlskills.com/blogs/paul/inside-the-storage-engine-how-are-allocation-unit-ids-calculated/和 m_objID。然后我通过执行以下命令在我的数据库之一上尝试：

    DBCC TRACEON(3604);
    DBCC PAGE (UFDATA_008_2013, 1, 73057, 3);
    GO

输出结果是：

    PAGE HEADER:


    Page @0x10008000

    m_pageId = (1:73057)                 m_headerVersion = 1                  m_type = 1
    m_typeFlagBits = 0x0                 m_level = 0                          m_flagBits = 0x8000
    m_objId (AllocUnitId.idObj) = 1913890731                                  m_indexId (AllocUnitId.idInd) = 0
    Metadata: AllocUnitId = 406903719657472                                   Metadata: PartitionId = 406903719657472
    Metadata: IndexId = 1                Metadata: ObjectId = 1913890731      m_prevPage = (1:92774)
