Instruction

Excellent! Let's review what we've learned in this part:

  • OVER(PARTITION BY x) is used to define and organize a window frame. PARTITION BY works like GROUP BY because it groups results by column values.
  • The grouping criteria can be a single column or multiple columns separated by commas.
  • Unlike GROUP BY, PARTITION BY does not collapse all the row details.
