Change Data Capture Functions (Transact-SQL)

[!INCLUDEtsql-appliesto-ss2008-xxxx-xxxx-xxx_md]

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.

cdc.fn_cdc_get_all_changes_<capture_instance> (Transact-SQL)	sys.fn_cdc_has_column_changed (Transact-SQL)
cdc.fn_cdc_get_net_changes_<capture_instance> (Transact-SQL)	sys.fn_cdc_increment_lsn (Transact-SQL)
sys.fn_cdc_decrement_lsn (Transact-SQL)	sys.fn_cdc_is_bit_set (Transact-SQL)
sys.fn_cdc_get_column_ordinal (Transact-SQL)	sys.fn_cdc_map_lsn_to_time (Transact-SQL)
sys.fn_cdc_get_max_lsn (Transact-SQL)	sys.fn_cdc_map_time_to_lsn (Transact-SQL)
sys.fn_cdc_get_min_lsn (Transact-SQL)
