Memory-Optimized Table Dynamic Management Views (Transact-SQL)

[!INCLUDEsql-asdb-asdbmi]

The following [!INCLUDEssNoVersion] dynamic management views (DMVs) are used with In-Memory OLTP:

Object Catalog Views

The following object catalog views are used specifically with In-Memory OLTP.

:::row::: :::column::: sys.hash_indexes (Transact-SQL) :::column-end::: :::column::: sys.memory_optimized_tables_internal_attributes (Transact-SQL) :::column-end::: :::row-end:::

Internal DMVs

There are additional DMVs that are intended for internal use only, and for which we provide no direct documentation. In the area of memory-optimized tables, undocumented DMVs include the following:

  • sys.dm_xtp_threads
  • sys.dm_xtp_transaction_recent_rows
