SQL Server : query columns to JSON object with group by

Question

I have a table with 3 columns, I want to query that table such that the result will be a JSON object.

Sample data looks like this:

 CREATE TABLE #Test (         


        

Answer 1

Try this:

SELECT (SELECT [ID], [Keys], [ValueV]  FOR JSON PATH)
FROM #Test 
GROUP BY ID, keys, ValueV

or this:

SELECT (SELECT [ID], [Keys], [ValueV]  FOR JSON PATH, WITHOUT_ARRAY_WRAPPER)
FROM #Test 
GROUP BY ID, keys, ValueV
