Change Data Capture Tables (Transact-SQL)

  • Artikkel

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

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.

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)
Returns the configuration parameters for change data capture agent jobs.
