Sometimes, in the quest for raw SQL performance, you are forced to sacrifice legibility and maintainability of your code, unless you then document your code lavishly.

Code coverage is a practice that goes hand in hand with automated testing, reporting the percentage of your code that has been exercised during a test run. Ed Elliott and Redgate have partnered to make a code coverage tool available for SQL Server, both free and open source. SQL Cover measures the coverage of your SQL Server stored procedures and functions. It has built-in support for the popular tSQLt unit testing framework, but can also be used alongside any automated testing framework of your choosing. Find out more in this blog post.

With database deployments, not all script-based processes are equal. Some use change scripts in a free-and-easy way, and some, which are normally called ‘migrations-based approaches’, have more discipline around them.

Dynamic Data Masking allows you to obscure your confidential data column values at the database engine level for both new and existing SQL Server data.
