— <b>1. Window functions for marketers</b> — running totals and first-touch ordering, the two you'll use weekly. Source: Mode SQL tutorial.
— <b>2. The join that's secretly a funnel</b> — left joins as the backbone of every drop-off analysis. Source: Select Star blog.
— <b>3. Date-truncation and cohorting</b> — grouping by signup week without a spreadsheet pivot. Source: Metabase learn.
— <b>4. Reading a query plan, lightly</b> — why your dashboard times out and the one index that fixes it. Source: PlanetScale blog.
Skip if your analyst answers everything same-day. Essential the first time you're blocked waiting on data.
That's the stack for this week. Forward to a teammate.
