cdc.lsn_time_mapping (Transact-SQL)

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

Returns one row for each transaction having rows in a change table. This table is used to map between log sequence number (LSN) commit values and the time the transaction committed. Entries may also be logged for which there are no change tables entries. This allows the table to record the completion of LSN processing in periods of low or no change activity.

We recommend that you don't query the system tables directly. Instead, execute the sys.fn_cdc_map_lsn_to_time (Transact-SQL) and sys.fn_cdc_map_time_to_lsn (Transact-SQL) system functions.

Column name	Data type	Description
start_lsn	binary(10)	LSN of the committed transaction.
tran_begin_time	datetime	Time that the transaction associated with the LSN began.
tran_end_time	datetime	Time that the transaction ended.
tran_id	varbinary(10)	ID of the transaction.
