Sum for multiple date ranges in a single call?

Question

I have the following query:

SELECT 
   SUM(\"balance_transactions\".\"fee\") AS sum_id 
   FROM \"balance_transactions\" 
   JOIN charges ON balance_transactions

Well coming from a SQL Server background I would change your where clause to

...
AND (
      "balance_transactions"."created" BETWEEN '2013-12-20' AND '2014-01-19'
      OR
      "balance_transactions"."created" BETWEEN '2013-12-21' AND '2014-01-20'
      OR
      "balance_transactions"."created" BETWEEN '2013-12-23' AND '2014-01-22'
      OR
      "balance_transactions"."created" BETWEEN '2013-12-24' AND '2014-01-23'
    );

Just be sure you have a good index on those dates! :)
