What may be the effects on software when a database table is changed?
When making changes to a database requires an object to be dropped and recreated, the DBA must cope with the cascading DROP effect. A cascading DROP refers to the effect that occurs when a higher-level database object is dropped: All lower-level database objects are also dropped.
What is the main purpose of relating data between tables in a database? To minimise duplication of data. What is created by matching a unique field in a table with a field in another table?
When does change data capture remain enabled in SQL?
SQL Server uses the following logic to determine if change data capture remains enabled after a database is restored or attached: If a database is restored to the same server with the same database name, change data capture remains enabled.
How to automate schema changes in SQL data?
The code logic ensures that no schema change statement is skipped, and all changes are applied even if the insertion is out of order. You can sync the schema change tracking table to all endpoints using the existing sync group or a new sync group.
Is there way to track data change in SQL Server?
Change data capture and change tracking can be enabled on the same database; no special considerations are required. For the editions of SQL Server that support change data capture and change tracking, see Features Supported by the Editions of SQL Server 2016. Change tracking is supported by SQL Database.
What happens when you change the schema of a table?
Sync succeeds after a retry. Renaming columns or tables makes Data Sync stop working. Create a new table or column, backfill the data, and then delete the old table or column instead of renaming. For other types of schema changes – for example, creating stored procedures or dropping an index- updating the sync schema is not required.
