Display return code of stored procedure in PowerApp

[Anonymous]

Hello,

I have a button in PowerApps which executes a stored procedure and I want to display a message if the stored procedure was executed successfully or not. I have tried doing this by adding an output but I cannot get the result to be displayed in a text field in PowerApps. 

Has anyone tried this successfully?

Have you tried storing the return code from the Flow in a variable in PowerApps and then binding the textbox to the variable.  As a declarative system PowerApps doesn't normally allow programmatic changes to object properties at runtime.  Usually you have to bind controls to variables and then change the value of the variable.

 YOur run statement should look something like this.

Set(returnvariablename, Flowname.run(input parameters if any))

Hello @Pstork1 ,

This is what I did, but the text field displays no value.  

Set(datafromflow, ExecuteSP.Run())

Did you look at the variable value itself using the menu in the designer to make sure that there was a return code?  That will tell you if its just not binding or if there is a problem saving the return code from the stored procedure and returning it to Powerapps.  It might be a Flow or a SQL issue rather than a PowerApps issue.

@Pstork1 ,

where can I see the return code in designer? I can see the data from the below print screen, but I am not sure if it is the right thing. Thank you.

Nope, that's the right place.  But if you look down into the Outputs section you will see that your result code is blank.  Double check your stored procedure to make sure its actually returning a result code.

Hello @Pstork1 ,

I have a return code in my procedure but it still does not return anything.

ALTER procedure [dbo].[TESTProc] as
BEGIN
SELECT 8/4
return 1
END

@Anonymous  i have this same issue, Did you made it work?

Hello @CodingCarnage ,

I used the following solution: 

In the stored procedure: 
DECLARE @ResultsTable TABLE (ErrorMessage varchar(500), ErrorCode VARCHAR(10), ReturnData NVARCHAR(MAX), ReturnMessage NVARCHAR(MAX))

Insert the desired values in the table: 

INSERT INTO @ResultsTable(ErrorMessage, ErrorCode, ReturnData , ReturnMessage)
VALUES ('1', '2', '3' , '4');

at the end of the stored procedure:

SET @JSON_OUTPUT= (SELECT ErrorMessage, ErrorCode, ReturnData , ReturnMessage from @ResultsTable FOR JSON AUTO, INCLUDE_NULL_VALUES )
end

In MS Flow use a parse JSON after the execution of the stored procedure:

Put this in schema:

{

    "type": "array",

    "items": {

        "type": "object",

        "properties": {

            "ErrorMessage": {

                "type": [

                    "string",

                    "null"

                ]

            },

            "ErrorCode": {

                "type": [

                    "string",

                    "null"

                ]

            },

            "ReturnData": {

                "type": [

                    "string",

                    "null"

                ]

            },

            "ReturnMessage": {

                "type": [

                    "string",

                    "null"

                ]

            }

        }

    }

}

Add a respond to a PowerApp or Flow node: https://ibb.co/0KPwPgm

Then you call the flow in PowerApps UpdateContext({flowResult: Flow.run(parameters of flow)})

Hope this helps.
