If auto-generate was selected for the primary key in the CDT, will the database create a new row if no ID is provided?

If auto-generate was selected for the primary key in the CDT, will the database create a new row if no ID is provided?

• A. True
• B. False
• C. Only sometimes
• D. Depends on the data type

Answer: (A)

When the primary key in a Complex Data Type (CDT) is set to auto-generate, it means that the database management system is configured to automatically create a unique identifier for each new record when none is provided. This functionality is beneficial because it ensures that every record can be identified uniquely without needing to manually supply an ID. In this context, if no ID is supplied when a new row is inserted into the database, the auto-generate feature kicks in and the database will indeed create a new row with a uniquely generated primary key. This automatic generation eliminates the potential for conflicts or duplicates, ensuring data integrity. Consequently, when the primary key is configured in this manner, the answer clearly indicates that a new row will be created if no ID is provided, as the system is designed to handle such inserts seamlessly and effectively.
