每个循环的逻辑应用程序以检测空白空间

Question

I have a Logic app with nested For each loop which has an array looped in as below:-

@items('For_each')?['TicketAssignedTo'] --> This could some times get black array values like "TicketAssignedTo": [ ] which make the loop to succeed but Insert SQL block within this loop would not execute. How to detect these blank values and make the control execute the inner block?

Answer 1

You can use the length function in the expression. Also be mindful to coalesce the value to an empty string before checking the length.

Answer 2

You can add a "If" condition in you logic app to judge the length of your array.

The expression of length is

but maybe you should use

length(body('xxx'))

it depends on the source of your array.
