statement can be accomplished in one of two ways, primarily depending upon which version of SQL Server you are using.
We’ll briefly explore both options so you can find what works best for you.
Now, the Log Reader Agent is created for the database and the capture job is deleted.
The Log Reader Agent continues to scan the log from the last log sequence number that was committed to the change table.
This section describes the change data capture security model.
Configuration and Administration To either enable or disable change data capture for a database, the caller of sys.sp_cdc_enable_db (Transact-SQL) or sys.sp_cdc_disable_db (Transact-SQL) must be a member of the fixed server sysadmin role.
Change data capture and transactional replication always use the same procedure, sp_replcmds, to read changes from the transaction log.
DDL Operations to Change Data Capture Enabled Source Tables When a table is enabled for change data capture, DDL operations can only be applied to the table by a member of the fixed server role sysadmin, a member of the database role db_owner, or a member of the database role db_ddladmin.
When both features are enabled on the same database, the Log Reader Agent calls sp_replcmds.
This agent populates both the change tables and the distribution database tables.
In change tracking, the tracking mechanism involves synchronous tracking of changes in line with DML operations so that change information is available immediately.
Change data capture provides historical change information for a user table by capturing both the fact that DML changes were made and the actual data that was changed.
These change tables provide an historical view of the changes over time.
