針對資料庫中所有資料表和大部分類型索引的每個資料分割,都各包含一個資料列。Contains a row for each partition of all the tables and most types of indexes in the database. 這個檢視表中不包含特殊索引類型,例如全文檢索、空間和 XML。Special index types such as Full-Text, Spatial, and XML are not included in this view. [SQL Server]SQL Server 中的所有資料表和索引都至少包含一個資料分割,不論它們是否進行明確的資料分割都一樣。All tables and indexes in [SQL Server]SQL Server contain at least one partition, whether or not they are explicitly partitioned.

資料行名稱Column name 資料類型Data type 描述Description
partition_idpartition_id bigintbigint 指出資料分割識別碼。Indicates the partition ID. 在資料庫中,這是唯一的。Is unique within a database.
object_idobject_id intint 指出這個資料分割所屬物件的識別碼。Indicates the ID of the object to which this partition belongs. 每份資料表或檢視表至少都是由一個資料分割組成。Every table or view is composed of at least one partition.
index_idindex_id intint 指出這個資料分割所屬物件內的索引識別碼。Indicates the ID of the index within the object to which this partition belongs.

0 = 堆積0 = heap
1 = 叢集索引1 = clustered index
2 或以上 = 非叢集索引2 or greater = nonclustered index
partition_numberpartition_number intint 這是在擁有索引或堆積內,以 1 為底的資料分割編號。Is a 1-based partition number within the owning index or heap. 如果是非資料分割的資料表和索引,這個資料行的值便是 1。For non-partitioned tables and indexes, the value of this column is 1.
hobt_idhobt_id bigintbigint 指出包含這個資料分割的資料列之資料堆積或 B 型樹狀目錄的識別碼。Indicates the ID of the data heap or B-tree that contains the rows for this partition.
