I have recently started using workflows and as every beginner I am flooded with questions.
I am not seeking for an essay type of answer but, just to give you an idea, of the type of questions I have when creating a flow:
@not(equals(items('Apply_to_each')?['a'], items('Apply_to_each')?['b']))what is the nomeclature for all the round and square brackets?
Again, as I said I am not looking for an answer here (but if you are kind enough to answer some of these Qs it will be much appreciated) but more like links (and books) that will help me understand it better.
P.S. I have been trying all day to create a formula within a "Compose" action that will take only the first three elements of an input array and I still cannot make it.
Many thanks in advance.
When working with Condition, in basic mode, the available conditions displayed on the condition card are “is equal to”, “contains”, etc.
While in advanced mode, we can use workflow definitions to configure the functions in different ways. For example, you can combine if function and equals function to return a specified value based on whether the expression resulted in true or false. This function if(equals(1, 1), 'yes', 'no') will return “yes”.
After you select a dynamic content from the previous step, in advanced mode, it will automatically generate the @ symbol and ?, the @ symbol is needed and you need to regard the “items('Apply_to_each')?['a']” as a whole.
When using the Compose action to get the first three elements of an input, please try to use the substring function, I assume it would work for you.
This documentation about workflow definition language would be a great help to you. Please check it at here for more details:
If you need more help, please feel free post back.
Many thanks for the lenghty post and the detailed answers, much appreciated.
The content of the link you posted I am afraid I cannot understand (I ahd a look at it in the past before I posted here) but many thanks anyway..
If you are unfamiliar with workflow definition language, I assume that this blog would help understand how to use expression in your flow. Please take it for a reference:
