Hi i have go a simple database with three fields :



Customer: Date: Amount:
ACME, 2018-01-01, 37.50


......



And want aggregate the amount per customer per month in a table.
The ideal would be:



month: 01,02,03,04,05,06,07,08,09,10,11,12
total: (sum of all sales per month)
acme : (sum of customer sales per month)
etc. ...


I thought a Crosstab like this would solve it, but I seem to be stuck here, any ideas:



SELECT *
FROM crosstab('SELECT "Customer", to_char("Date",'MM') as "Month",sum("Amount") as "Sale" FROM Sales where "Date">'2018-01-01' GROUP BY 1,2') as "Month" ("Customer" varchar, "Sale" real);
