Analytics Made Simple

Category: SQL

You are here if you have a table and a question, and another export into a sheet is how the answer gets worse. These articles are the SQL series in category form. The numbered tutorials start with a playground and the core commands, then reading rows, filtering, sorting, grouping, and joins. Later tutorials cover subqueries, changing rows, views and indexes, and making a query faster and easier to keep. One extra primer, outside that numbered run, asks what SQL is and why you would learn it.
Do not start in the middle because a title mentions joins. Joins make sense after you can read and filter a single table. The series hub states the order. The category page is only the shelf.
Where to start: open the SQL series. Use the first part on that page. If you only needed the word, the primer is enough. If you need to write the query on Monday, use the playground and go in order.
