Exercise2

Workflow: Chapter 7/Exercise 2

In this exercise, we create a course schedule for the next 12 months using a Counting Loop.

We are asked to schedule one course each month, the first course taking place on January 15, 2011. We use a Table Creator node to input the first date as a String and then convert it to a Date object. Note, that you can also create a single Date value with the Date&Time Range Creator node (specify the start date and set the number count to 1).

Within the loop, we take the start date and shift the date by x months where x is equal to the current loop iteration. So, in the first iteration we shift the date by 0 months, then 1 month, 2 months, etc. To define the shift value we use a flow variable which we create in the Variable Expression node.

Lastly, after concatenating all intermediate results, we add the instructor and location to each course.
