Overview As we all know, data security is a never-ending battle. Every day, we hear of new data breaches. It's a hard problem, and there is no single solution, other than a defense in depth. Let's look at one of those defenses for databases: query control. Query control is a simple idea: most applications access […]
The first poll question of the year has Steve asking you to look back at 2021 and pick something good that happened.
You can define policies for your Azure SQL Databases for security and meeting your organization’s standards. Management groups simplify policies over multiple subscriptions. Michael Wood explains Azure Policies and Management Groups.
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.
Problem Some time ago Argenis Fernandez(@DBArgenis) found and described a vulnerability that allows you to get into SQL Server with 'sa' rights. This method does not require a restart of the SQL Server service or the whole machine, the condition is a local administrator account on the server. Reminder SQL Server until 2008R2: Until SQL 2008R2, […]

In thinking about the differences between the identity property and a sequence object, which of these two guarantees that there are consecutive numbers (according to the increment) inserted in a single table?
