The new SQL Server version (SQL Server 2022 Preview) is now available and there are some improvements related to security. There are also a couple of new built-in (fixed) server-level roles that were introduced in SQL Server 2022. Separation of duties and a principle of minimal permissions are SQL Server security best practices and we will cover how to use these new security features.

Sparse columns were added with SQL Server 2008 as a new feature that helps save space when columns have a high ratio of NULL values. We have a couple of very large and wide tables with Nullable columns and most of them don’t have data. We’d like to take advantage of sparse columns to save space. We ran SSIS (SQL Server Integration Services) Data Profiling Task to find sparse columns candidates (Null Ratio profile). With more than 500 candidate columns it will be hard to review and alter each column individually. How can we use the SSIS Data Profiling output XML file? Can we generate a script to modify columns based on Data Profiling output and apply to this script sparse columns requirements/restrictions?

Dropping SQL Server logins without dropping associated the database users creates orphaned database users. By default, the DROP LOGIN statement in SQL Server only removes logins, but not database(s) users that are linked to these logins. The best practice is to delete all databases users that are mapped to this login first and then delete the login itself. When logins are deleted, and users remain orphaned, DBAs have a cleanup task to perform from time to time. This is to make sure that an orphaned user is not misused (to prevent a potential security issue). How can we make sure that we don’t forget to delete database users before dropping logins?

SQL Server security monitoring is a critical part of the Database Administrator’s job. Some security related alerts could be setup very easy, but others require third-party tools or extra steps to setup. For example, SQL Server Audit can be used to monitor logins or users modification, but it requires audit log review. We would like to get real-time alerts every time a login or a user is created or added to a server or a database role, how can this be done?
In this tip we will provide steps and scripts for setting up WMI alerts and jobs responding to these alerts to monitor the creation and removal of users and logins as well as server and database roles membership changes.

Central Management Server (CMS) is a SQL Server feature that allows you to manage multiple SQL Servers at the same time. You can run T-SQL scripts or execute Policy-Based Management policies on multiple servers. You can also group SQL Servers and run the scripts on a specific group of SQL Servers.
How else can CMS be used? How can we overcome some of the limitations when we run queries against CMS Server Groups?
In this tip we will show you a couple of CMS tricks. In our examples below we will show how you can sort the CMS query results for different scenarios. We will also provide a couple of examples of alternative uses of CMS.
