Exercise

Calculating mode (I)

Unfortunately, there is no function to calculate the mode, the most recurring value in a column. To calculate the mode:

  • First, create a CTE containing an ordered count of values using ROW_NUMBER()
  • Write a query using the CTE to pick the value with the highest row number

In this exercise, you will write the CTE needed to calculate the mode of OrderPrice.
