Use Flyway to run your database migrations, each time automatically creating a SQL Change Automation release object to provide object-level scripts and a build script for the new version, along with change reports and code analysis reports.
Steve notes the changes in the world might affect how to view and use data in our work.
The UNPIVOT operator does just the opposite of the PIVOT operator, which we looked at in the previous level. By using the PIVOT operator we can take multiple rows of data and create as single row as output. The UNPIVOT operator will take values from a single row and will create multiple rows. Microsoft introduced the UNPIVOT operator when they rolled out SQL Server 2005. In this level I will be showing you different examples of how to use the UNPIVOT operator.
Phil Factor presents a useful but slightly flawed 'table report' script as an adventure playground for exploring SQL Code analysis issues. He demonstrates use of the auto-fix feature, to arrive at a pristine script free from wavy green underlines.
Developers can work with multiple range values at once using sp_sequence_get_range. Greg Larsen explains how to return multiple sequence numbers with sp_sequence_get_range.
Steve wishes we could do some data cleanup and archival every year. Or even more often.

LaunchCode provides free tech training, paid apprenticeships, and career support to hundreds of people who have the ability and interest but not always the opportunity to land tech careers. For example, not having a college degree can eliminate […]
