Hello 

 

I have the following flow that executes a SQL Server stored procedure with 2 parameters -

It works when it returns rows, but flags up an error when no rows are returned.

 

How do I handle that? 

 

Any help would be greatly appreciated.

 

Thanks

 

Kevin

    Hi @KevBarrie  ,

     

    You can maybe have two response actions based on how many rows are returned. So a condition to check the length of the array(rows) returned can be added. 

     

    If length > 0 , then you can use the above response in the else part you can use another response , which will return just a message stating no rows matching this condition were returned.

     

    Hope this helps!

     

    Thanks!

    Hello

     

    I have tried the following -

     

    KevBarrie_0-1692261999184.png

     

    I am checking - 

    length(outputs('Execute_stored_procedure_(V2)')?['body'].ResultSets.Table1) > 0
     
    It works if the stored procedure returns records, however, when it doesn't, still getting the error - 
    "Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template language expression 'length(outputs('Execute_stored_procedure_(V2)')?['body'].ResultSets.Table1)' cannot be evaluated because property 'Table1' doesn't exist, available properties are ''. Please see https://aka.ms/logicexpressions for usage details.'."

    Any ideas what I am doing wrong?
