transposing multiple rows into multiple columns of single row

My SQL query SUMs up sales transactions by day by revenue center by customer type (3 types).
It results a queryset with 3 rows - 1 for each of 3 member types -- date / revenue center ID / daily sales total
I want an output that shows date / revenue center ID / daily sales total (TYPE 1) / daily sales total (TYPE 2) / daily sales total (TYPE 3)
How can I transpose 3 rows into 3 columns?
It needs to process multiple days at once, as there are 3 years of data in that table and it's added to each night for previous day's transactions.
