cdc.captured_columns (Transact-SQL)
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Returns one row for each column tracked in a captured instance. By default, all columns of the source table are captured. However, columns can be included or excluded when the source table is enabled for change data capture by specifying a column list. For more information, see sys.sp_cdc_enable_table (Transact-SQL).
We recommend that you do not query the system tables directly. Instead, execute the sys.sp_cdc_get_source_columns stored procedure.

| column_name | sysname | Name of the captured column. |
| column_id | int | ID of the captured column within the source table. |
