Software development can be a complicated dance. Most of us do not work for a software vendor and don't have the strict requirements for our deployments when we control the client systems. That doesn't mean it's easier for us, especially as our environments grow more complex and the availability of our systems becomes more important. Application changes can become disconnected from the database changes, especially when the scope or scale of the change is large, which can present problems.

Making database changes can be challenging since we must ensure that our data is not lost as objects are altered. We have to ensure that any application functions that depend on a certain schema receive the data they need, without unnecessary errors. The timing of changes becomes more important in the database than in applications in many situations. This Friday I am curious how many of you decide to stage these changes in your environment. If you have dependent changes, I'm wondering if you might alter the database first and change the application in a later deployment.

How many of you deploy database changes before code changes?

By "before" I mean you deploy the database changes, possibly making some application changes, but there are other code changes deferred for a separate deployment at a later time. The use of views, defaults, optional parameters and more allow database changes to proceed without accompanying application changes. It may require a bit more work, but the database can potentially be changed during a less busy time, even if development or testing for the all the application changes is not complete.

The future will require more availability and stability from our systems as they become more essential to our organizations. Learning to update software, and databases, with minimal disruption is a skill that will set you apart in the future.

Select which of the following statements are true with respect to the NEXT VALUE FOR function used for SEQUENCE Object. (choose 2)

By Lokesh Vij

Answer:

• Sub clause "PARTITION BY" is not supported when NEXT VALUE FOR function is used with OVER Clause
• Can be used in stored procedures.

Explanation: The NEXT VALUE FOR function can be used in stored procedures and triggers. An OVER clause applied to the NEXT VALUE FOR function does not support the PARTITION BY sub clause. The NEXT VALUE FOR function cannot be used in views, in user-defined functions, or in computed columns.
