THIS TOPIC APPLIES TO:yesSQL Server (starting with 2008)noAzure SQL DatabasenoAzure SQL Data Warehouse noParallel Data Warehouse

Returns one row for each data definition language (DDL) change made to tables that are enabled for change data capture. You can use this table to determine when a DDL change occurred on a source table and what the change was. Source tables that have not had DDL changes will not have entries in this table.

We recommend that you do not query the system tables directly. Instead, execute the sys.sp_cdc_get_ddl_history stored procedure.

Column nameData typeDescription
