Snowflake is all about staying up-to-date and cool, regularly spicing up its lineup of awesome features to keep up with the changing times in the world of data. So, in this blog post, get ready for a front-row seat to the show as I walk you through these cool updates and show you exactly how to use them to make your data game even stronger. This dataset contains 11 columns. If you want to exclude multiple columns at once, all you have to do is put those columns together within a set of trusty brackets:. Think of it as a sibling to the exclude feature we talked about earlier; it functions in a similar manner:. Imagine the dataset we explored earlier. In such a scenario, the benefit of utilising GROUP BY ALL becomes apparent — it spares us the effort of individually listing each column in the group by statement, as demonstrated in the following instance:. While this example may appear straightforward, consider the potential convenience when dealing with a large number of columns within your SELECT statement. Just envision the efficiency boost that awaits in such scenarios.
