DBCC IND 命令

DBCC IND是一个非正式的命令，用于定位到表或索引使用的Page，该命令的语法结构是：

DBCC IND ( ['database name'|database id], table_name,index_id)

参数index_id的有效值是：

• 1：表示表的聚集索引
• 非聚集索引的index_id
• 0：代表堆（没有创建聚集索引的表）
• -1：表示跟表相关的所有类型的Page（in row data, row over flow data, IAM, all indexes）
• -2：只显示IAM类型的Page

该命令返回的结果如下所示：

结果集中各个字段的含义：

• PageFID — the file ID of the page
• PagePID — the page number in the file
• IAMFID — the file ID of the IAM page that maps this page (this will be NULL for IAM pages themselves as they’re not self-referential)
• IAMPID — the page number in the file of the IAM page that maps this page
• ObjectID — the ID of the object this page is part of
• IndexID — the ID of the index this page is part of
• PartitionNumber — the partition number (as defined by the partitioning scheme for the index) of the partition this page is part of
• PartitionID — the internal ID of the partition this page is part of
• iam_chain_type — see IAM chains and allocation units in SQL Server 2005
• PageType — the page type. Some common ones are:

  • 8 – GAM page 
  • 9 – SGAM page 
  • 10 – IAM    page
  • 11 – PFS page
• IndexLevel — what level the page is at in the index (if at all). Remember that index levels go from 0 at the leaf to N at the root page
• NextPageFID and NextPagePID — the page ID of the next page in the doubly-linked list of pages at this level of the index
• PrevPageFID and PrevPagePID — the page ID of the previous page in the doubly-linked list of pages at this   level of the index
