How to pivot Spark DataFrame?

Question

I am starting to use Spark DataFrames and I need to be able to pivot the data to create multiple columns out of 1 column with multiple rows. There is built in functionality

Answer 1

There are plenty of examples of pivot operation on dataset/dataframe, but I could not find many using SQL. Here is an example that worked for me.

create or replace temporary view faang 
as SELECT stock.date AS `Date`,
    stock.adj_close AS `Price`,
    stock.symbol as `Symbol` 
FROM stock  
WHERE (stock.symbol rlike '^(FB|AAPL|GOOG|AMZN)$') and year(date) > 2010;


SELECT * from faang 

PIVOT (max(price) for symbol in ('AAPL', 'FB', 'GOOG', 'AMZN')) order by date;
