05. Quiz: Window Functions 2
Creating a Partitioned Running Total Using Window Functions
Now, modify your query from the previous quiz to include partitions. Still create a running total of standard_amt_usd
(in the orders
table) over order time, but this time, date truncate occurred_at
by year and partition by that same year-truncated occurred_at
variable. Your final table should have three columns: One with the amount being added for each row, one for the truncated date, and a final column with the running total within each year.
Workspace
This section contains either a workspace (it can be a Jupyter Notebook workspace or an online code editor work space, etc.) and it cannot be automatically downloaded to be generated here. Please access the classroom with your account and manually download the workspace to your local machine. Note that for some courses, Udacity upload the workspace files onto https://github.com/udacity, so you may be able to download them there.
