Exploring DuckDB - Part 2 (Dates, Times, CLI) In the previous posts, we went through setting up DuckDB and exploring DuckDB for common tasks involving importing data, aggregate queries and type casting. In this post. we continue our exploration by looking at some more common things we need, especially around date and time functions. We use the same dataset as before. so be sure to read either the full post. or at least the background to the sample data in that post, before jumping in. As before, most of these tips may apply to any language from which you execute queries, but I ran all of these from the official DuckDB command line application. In this post. we will look at common things to do with: * Working with Dates and Times * CLI dot commands * Command Line Options for the CLI client
