I'm really trying to understand how the tablefunc crosstab function works, to no avail.
I have a table that looks like this:
customer_id integer
date timestamp with time zone
amount numeric(10,4)
There are rows in this table every-time a customer gets charged an amount, which is multiple times per day.
I would like to get a result like this:
customer_id,day1,day2,day3,(…)
1,400.00,500.01,123.00,(…)
So, one row for each customer id and a column for every day in the current month. Anyone used crosstab for something
likethis?
Thanks for your help,
A.
