Why a monitoring tool is an essential tool for growing server estates
I enjoyed writing scripts to manage the servers, as it taught me a lot about the internals of SQL Server. Many of these scripts were eventually automated using SQL Server’s agent to run and save data on the different servers so we could review the results, looking for issues.

Benefits and Limitations of SCHEMABINDING Views in SQL Server
The tip, Views in SQL Server, explored the purpose of views, creating views examples, and benefits of views.

What if someone changes the underlying table structure, such as renaming the column, adding a new column, or dropping the table? What is the impact of changing schema on views? How can we stop any schema changes if the view references the schema?

Use DDL Triggers to Automatically Keep SQL Server Views in Sync
As much as we tell people to use SCHEMABINDING and avoid SELECT *, there is still a wide range of reasons people do not. A well-documented problem with SELECT * in views, specifically, is that the system caches the metadata about the view from the time the view was created, not when the view is queried. If the underlying table later changes, the view doesn't reflect the updated schema without refreshing, altering, or recreating the view. Wouldn't it be great if you could stop worrying about that scenario and have the system automatically keep the metadata in sync?
