63. Practicing queries on virtual datasets with UNION

We’re transitioning from beginner level of data and SQL to intermediate. 🍾 We’re locked in on becoming advanced users. In the upcoming lessons we’ll cover a lot of serious SQL techniques: joining tables, window functions, tons of new scalar functions and more. At the same time we’ll be learning about Bindle datasets and how data works in general. This mix could easily be overwhelming.

💡 To simplify things we can practice SQL separately from Bindle dataset. We can create virtual tables with just a handful of records and run queries there.
