Rankings and running totals

Rank rows and add running totals without grouping them away.

GROUP BY collapses rows into one per group. Window functions calculate across rows but keep every row, so you can show a rank or a running total next to the detail.

OVER says which rows to look at. ORDER BY inside it sets the order, and PARTITION BY restarts the calculation for each group.

What you’ll do

• Rank everyone
• Rank within each group
• Add a running total
