问题
I'm using SQL SERVER 2016 JSON result, but I don't know why it converts everything to array, e.g. if I execute the following query it returns an array instead of an object:
SELECT 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH
The result is:
[{"One":1,"Two":2,"Three":3}]
But I would like it to return:
{"One":1,"Two":2,"Three":3}
Also I tested this query, but the result was the same, again an array:
SELECT TOP 1 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH

You just need the WITHOUT_ARRAY_WRAPPER option:
SELECT 1 AS One,2 AS Two,3 AS Three
FOR JSON PATH ,WITHOUT_ARRAY_WRAPPER;
