Returns information about transactions at the database level.

To call this DMV from [!INCLUDEssazuresynapse-md] or [!INCLUDEssPDW], use the name sys.dm_pdw_nodes_tran_database_transactions. [!INCLUDEsynapse-analytics-od-unsupported-syntax]
| Column name | Data type | Description |
|---|---|---|
| transaction_id | bigint | ID of the transaction at the instance level, not the database level. It is only unique across all databases within an instance, but not unique across all server instances. |
| database_id | int | ID of the database associated with the transaction. In [!INCLUDE ssazure-sqldb], the values are unique within a single database or an elastic pool, but not within a logical server. |
| database_transaction_begin_time | datetime | Time at which the database became involved in the transaction. Specifically, it is the time of the first log record in the database for the transaction. |
| database_transaction_type | int | 1 = Read/write transaction 2 = Read-only transaction 3 = System transaction |
| database_transaction_state | int | 1 = The transaction has not been initialized. 3 = The transaction has been initialized but has not generated any log records. 4 = The transaction has generated log records. 5 = The transaction has been prepared. 10 = The transaction has been committed. 11 = The transaction has been rolled back. 12 = The transaction is being committed. (The log record is being generated, but has not been materialized or persisted.) |
| database_transaction_status | int | [!INCLUDEssInternalOnly] |
| database_transaction_status2 | int | [!INCLUDEssInternalOnly] |
| database_transaction_log_record_count | bigint | Applies to: [!INCLUDEsql2008-md] and later. Number of log records generated in the database for the transaction. |
| database_transaction_replicate_record_count | int | Applies to: [!INCLUDEsql2008-md] and later. Number of log records generated in the database for the transaction that is replicated. |
| database_transaction_log_bytes_used | bigint | Applies to: [!INCLUDEsql2008-md] and later. Number of bytes used so far in the database log for the transaction. |
| database_transaction_log_bytes_reserved | bigint | Applies to: [!INCLUDEsql2008-md] and later. Number of bytes reserved for use in the database log for the transaction. |
| database_transaction_log_bytes_used_system | int | Applies to: [!INCLUDEsql2008-md] and later. Number of bytes used so far in the database log for system transactions on behalf of the transaction. |
| database_transaction_log_bytes_reserved_system | int | Applies to: [!INCLUDEsql2008-md] and later. Number of bytes reserved for use in the database log for system transactions on behalf of the transaction. |
| database_transaction_begin_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. Log sequence number (LSN) of the begin record for the transaction in the database log. |
| database_transaction_last_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. LSN of the most recently logged record for the transaction in the database log. |
| database_transaction_most_recent_savepoint_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. LSN of the most recent savepoint for the transaction in the database log. |
| database_transaction_commit_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. LSN of the commit log record for the transaction in the database log. |
| database_transaction_last_rollback_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. LSN that was most recently rolled back to. If no rollback has taken place, the value is MaxLSN. |
| database_transaction_next_undo_lsn | numeric(25,0) | Applies to: [!INCLUDEsql2008-md] and later. LSN of the next record to undo. |
| pdw_node_id | int | Applies to: [!INCLUDEssazuresynapse-md], [!INCLUDEssPDW] The identifier for the node that this distribution is on. |
| database_transaction_first_repl_lsn | numeric(25,0) | Applies to: [!INCLUDEssazuresynapse-md], [!INCLUDEssPDW] LSN of the first log record in the transaction which needs replication. |
On [!INCLUDEssNoVersion_md] and SQL Managed Instance, requires VIEW SERVER STATE permission.
On SQL Database Basic, S0, and S1 service objectives, and for databases in elastic pools, the server admin account, the Microsoft Entra admin account, or membership in the ##MS_ServerStateReader## server role is required. On all other SQL Database service objectives, either the VIEW DATABASE STATE permission on the database, or membership in the ##MS_ServerStateReader## server role is required.
Requires VIEW SERVER PERFORMANCE STATE permission on the server.
