Now that we have our feet wet, let’s get started with the next puzzle. In this puzzle we will write a query that returns Percentage Growth Year over Year. For example, if sales were $258,056 in 2006 and $389,456 in 2007, then the percentage growth would be (2007 sales – 2006 sales)/2006 sales. Here are the requirements:
Columns: Internet Sales Amount and Percentage Growth (calculated measure) Rows: Calendar Years Filter: Only Show United States Bike Sales Hint: You can use the CREATE MEMBER statement to perform the calculation and use it in your query. You may also need to use a CASE Statement to address a Divide By Zero error. |
Remember, don’t post you solutions here. Save them for my solution post. I will post it along with the steps that was taken to solve the puzzle in a couple of days. Here is a screen shot of what the results should look like:
Don’t forget to check back in a couple days for the solution.
