In Presto, you can pivot data without using aggregation functions by using the CASE
statement to create separate columns for each distinct value that you want to pivot on.
Here's an example of how you can pivot data without aggregation in Presto:
1 2 3 4 5 6 7 8 9 |
SELECT ID, MAX(CASE WHEN category = 'A' THEN value END) AS A, MAX(CASE WHEN category = 'B' THEN value END) AS B, MAX(CASE WHEN category = 'C' THEN value END) AS C FROM table_name GROUP BY ID; |
In this example, we are pivoting the data based on the 'category' column, creating separate columns for each distinct category ('A', 'B', 'C') and their corresponding values using the CASE
statement. The MAX
function is used to get the maximum value for each category, but since there is only one value for each category, it essentially just performs the pivot without aggregation.
