Package configuration allows us to retrieve variable values from a variety of sources. We recently looked at storing the values in a SQL database. We can elevate the database configuration a step further by using system level Environment Variables. In this post we’ll walk through that process. Using environment variables Where we previously looked at storing […]
When building data solutions we’ll be handling sets of data which may need to be imported, transformed, aggregated or exported amongst other things. With more complex solutions can come a need to share this data between different areas of the process. Last week we looked at being able to share individual values within a session and […]
When developing application code we may be familiar with exchanging data and objects through the application. This practice is much less common in SQL due to being transactional when we consider application / OLTP workloads. There are however some times when exchanging values between code in the same session which is what we’ll start to […]
Last time out we looked at how data can be persisted even with a ROLLBACK being executed. Here we’re going to take that and look at an example of using it in action. We’ll generate some data – which may be good or bad – and try to add it to a table. If there’s any bad data […]
We recently looked at the impact of rolling back transactions on statistics and I thought it would be worth following this up to look at some other objects to see how they behave when a rollback occurs. When rolling back transactions we expect any changes to be rolled back. This isn’t always the case with data, just […]
