Returning JSON from Execute Stored Procedure and parsing it with Parse JSON



I am trying to parse the JSON returned by a stored procedure. The JSON string is built inside SQL stored procedure using SELECT ... from @Table FOR JSON PATH

The result of the stored procedure is as follows:

"OutputParameters": {},
"ResultSets": {
"Table1": [
"Column1": "[{\"ErrorM\":\"\",\"ErrorC\":\"\",\"ReturnD\":null,\"ReturnM\":\"bla\"}]"
I am trying to parse this result using the Parse JSON step, but somehow it sees the above Column1 as an array, not as an object. 
What could I do in order to be able to extract the data from te procedure as it is, a JSON, not an array?
Thank you.

Hi @omh ,


From the output you provide, the value of Column1 is a string, which is the value enclosed in double-quotes.


If it is array, it should be "Column1": [{\"ErrorM\":\"\",\"ErrorC\":\"\",\"ReturnD\":null,\"ReturnM\":\ "bla\"}].


You could parse this output using Parse JSON. I tested it on my side and it seems that there is no issue.

Hello @v-bacao-msft ,


Is there any way to return an array from the sql procedure? Even if I set the return as JSON, I get the output as a string..


My script from SQL is 

SELECT ErrorMessage, ErrorCode, ReturnData , ReturnMessage from @ResultsTable FOR JSON PATH , INCLUDE_NULL_VALUES

Hi @v-bacao-msft ,


Could you please share the flow configuration and the JSON schema?


Thank you.

Hi @omh , I use stored procedures a lot with Flow (mostly from OnPremises SQL Servers).
But I've never used the FOR JSON PATH , INCLUDE_NULL_VALUES syntax, just the regular SELECT and then parse the results in Flow.

Works like a charm for me.

Hello @Maurits ,


Thank you for your answer. This is what I successfully managed to do..but the request is to return the data as a JSON string.

That's what I do too most of the times.
Like image below, Flow is executed from a PowerApp.
It executes a stored procedure. The Response action sends the data back to the PowerApp.
The Response action actually creates the JSON string format based on the desired schema I supplied.



Hello @Maurits,


This is the configuration of my flow and the result of the stored procedure.  I managed to extract the data in the end, but I don;t know if this is a "happy" path 🙂  StoredProcedure Output.PNGJSON Configuration.PNG
