Change tracking - sys.dm_tran_commit_table

[!INCLUDE sql-asdb-asdbmi-asa-pdw]

Displays one row for each transaction that is committed for a table that is tracked by [!INCLUDE ssNoVersion] change tracking. The sys.dm_tran_commit_table management view, which is provided for supportability purposes and exposes the transaction-related information that change tracking stores in the sys.syscommittab system table. The sys.syscommittab table provides an efficient persistent mapping from a database-specific transaction ID to the transaction's commit log sequence number (LSN) and commit timestamp. The data that is stored in the sys.syscommittab table and exposed in this management view is subject to cleanup according to the retention period specified when change tracking was configured.

Note

To call this from [!INCLUDE ssazuresynapse-md] or [!INCLUDE ssPDW], use the name sys.dm_pdw_nodes_tran_commit_table. [!INCLUDE synapse-analytics-od-unsupported-syntax]

Column name Data type Description
commit_ts bigint A monotonically increasing number that serves as a database-specific timestamp for each committed transaction.
xdes_id bigint A database-specific internal ID for the transaction.
commit_lbn bigint The number of the log block that contains the commit log record for the transaction.
commit_csn bigint The instance-specific commit sequence number for the transaction.
commit_time datetime The time when the transaction was committed.
pdw_node_id int Applies to: [!INCLUDE ssazuresynapse-md], [!INCLUDE ssPDW]

The identifier for the node that this distribution is on.

Note

The table sys.dm_tran_commit_table will not reflect live changes for read-only users, as VIEW SERVER STATE permission is required. The changes remain stored in the rowstore until a CHECKPOINT occurs, following which read-only users will see them reflected. This behaviour isn't observed for SA users.
