Need help writing a condition for a SQL Stored Procedure

This is probably incredibly easy, but I am struggling.  I want to write a scheduled flow that calls a stored procedure from SQL and if the Stored Procedure returns results, then send an email with an html table of those results.  If no results are returned, then do nothing.

The part I am having trouble with is choosing a value for the condition.  I want it to just be "is not null" but that isn't a choice.  I'm confused by all the different values, parameters, dynamic content, and expressions and am not sure how to write what I want.  I've tried length is greater than 0 but that failed and I feel like I'm just poking around in the dark.

Please help! Thanks!

Hello @Anonymous 

Please, rename the action "execute stored procedure (v2)" by "execute stored procedure" or maybe changing the expression:

not(empty(body('execute_stored_procedure_(v2)')?['resultsets']))

Hope it helps!

Hello @Anonymous 

Please, have a look at this solution by @v-xida-msft : https://powerusers.microsoft.com/t5/Building-Flows/Checking-for-empty-stored-procedure-result/td-p/63791

Basically, the condition should be the following:

@not(empty(body('execute_stored_procedure')?['resultsets']))

Hope it helps!

Thank you for your quick reply, and pointing me to the other post which I clearly missed when I searched.  But my Conditions step looks different from that poster.  And although I added only one "@" it seems to have added more when I saved.  When I tested the flow it ran successfully but did not generate an email, even though I know the stored procedure as it is written is returning results.Screen Shot 2020-05-22 at 12.35.18 PM.png

Hello @Anonymous 

Try the following expression:

Using "dynamic expressions" on both sides of the condition.

Hope it helps!

I think I got the text the same as you, but I'm getting this error now; The template validation failed: 'The action(s) 'execute_stored_procedure' referenced by 'inputs' in action 'Condition' are not defined in the template.'.

Actually.. I didn't test enough before saying it resolved it.... it seems as though even when the PROC isn't returning any result, it is still firing an email that has no content.  So I need to tweak it a little more.  But I do very much appreciate you getting me as far as you did @fchopo
