What's Wrong?

pivot does not support subquery

How to Reproduce?

referenced document: https://docs.databend.com/sql/sql-commands/query-syntax/query-pivot

error sql:

SELECT * 
FROM (select * from monthly_sales)
PIVOT(SUM(amount) FOR MONTH IN (select distinct month from monthly_sales))
ORDER BY EMPID;

If I use a view, databend can support subquey in from:

create view v_monthly_sales as select * from monthly_sales;
 
SELECT * 
FROM v_monthly_sales
PIVOT(SUM(amount) FOR MONTH IN ('JAN', 'FEB', 'MAR', 'APR'))
ORDER BY EMPID;

Assuming all months are in the results and need to be used, how can I do the query correctly without writing a for?
