Change Data Capture Functions (Transact-SQL)

[!INCLUDE SQL Server]

Change data capture records insert, update, and delete activity applied to [!INCLUDEssNoVersion] tables, supplying the details of the changes in an easily consumed relational format. Column information that mirrors the column structure of a tracked source table is captured for the modified rows, along with the metadata needed to apply the changes to a target environment. The following functions are used to return information about the changes.

:::row::: :::column::: cdc.fn_cdc_get_all_changes_<capture_instance> (Transact-SQL) :::column-end::: :::column::: sys.fn_cdc_has_column_changed (Transact-SQL) :::column-end::: :::row-end:::
