Change Data Capture Tables (Transact-SQL)
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 topics in this section describe the system tables that store information used by change data capture operations.
In This Section
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)
