Which operator would you use to compute the maximum numeric value in a column, ignoring NULLs?

Explanation:
Finding the maximum value in a column while skipping NULLs is done with the MAX function. MAX examines all non-null values and returns the largest one, ignoring any NULLs. For example, with values 2, NULL, 7, and 5, MAX yields 7. If every value is NULL, the result is NULL. Other aggregates do different things: MIN gives the smallest non-null value, AVG computes the average of non-null values, and SUM adds the non-null values. Use MAX when you specifically need the highest value in the data set.
