Change data capture enables change tracking on tables so that data manipulation language (DML) and data definition language (DDL) changes made to the tables can be incrementally loaded into a data warehouse. The articles in this section describe the system tables that store information used by change data capture operations.
cdc.<capture_instance>_CT
Returns one row for each change made to a captured column in the associated source table.
cdc.captured_columns
Returns one row for each column tracked in a capture instance.
cdc.change_tables
Returns one row for each change table in the database.
cdc.ddl_history
Returns one row for each data definition language (DDL) change made to tables that are enabled for change data capture.
cdc.lsn_time_mapping
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.
cdc.index_columns
Returns one row for each index column associated with a change table.
dbo.cdc_jobs (Transact-SQL)
Returns the configuration parameters for change data capture agent jobs.
