How to take max between two values in presto?

@samara 

You can take the maximum between two values in Presto using the GREATEST function. Here is an example:

1

SELECT GREATEST(10, 20) AS max_value;

This query will return the maximum value between 10 and 20, which is 20 in this case. You can replace 10 and 20 with any values you want to compare.
