When you’re developing a new database solution you’ll inevitably want to apply some security to that data. If you have complex security requirements with users being members of multiple groups or implementing multiple roles within the database it can become tricky to ensure that everything is working exactly as you like. It’s certainly a hassle […]
We’ve recently been looking at temporal tables, how they work, we query them and how to modify them. All of these are consistent since the feature was added in SQL Server 2016. There are however a couple of extra features which were added in 2017 to make these even more usable. Let’s use our previous […]
Recently we’ve been looking at temporal tables including the basics for using them and options for querying them. Continuing with this theme – and given that tables rarely remain static – we’ll look at what we might need to consider when modifying their structure. As with the previous posts we’ll start our with our sample […]
This month’s invitation from Kenneth Fisher asks us to share our first tech job. As he points out there are a lot of DBAs who don’t start out working with databases and we slowly succumb to the dark side (my words, not his), intentionally or otherwise. During a gap year whilst at university I joined […]
During our initial introduction we briefly saw how to query temporal tables but there were a couple of specific bits which I wanted to cover around querying these tables. The first of these concerns the point in time we query against and the second is how we go about using that point in time to […]
Last time out we took a brief look at temporal tables, how to create them and what they can do for us. This time I’d like to dive a bit deeper into them and see how they look under the covers. For this we’ll be using the same table which we ended up creating previously: […]
With the arrival of SQL Server 2016 we were provided with a new feature in the engine called System Versioned Temporal Tables – typically shortened to Temporal Tables. These tables allow us not only to query the data as it currently is, but also query it at any point in the past too as it […]
This month’s invitation from Camila Henrique asks us for advice we’d give to our younger selves in our T-SQL journey. Coming from the SQL Server perspective there’s a huge variety of areas within the stack where you might want to provide some advice but I’m going to focus on the scripting and querying as that’s […]
Last time out we looked at how to add parameters in a Reporting Services report. In there we looked at adding a parameter where only a single value was selected by the user. We also have the option to allow selection of multiple values for parameters, for example the selection of multiple sales regions or […]
Adding parameters into a report or dashboard you’re publishing with Reporting Services can add that extra shine. It allows the end users to tailor their experience and can allow for the same report to meet different needs. This may require a little extra effort by the developer if you’re looking to go and retrospectively update […]
