How may we handle FOR JSON PATH
queries with ERLANG ODBC?
I have the following simple query in SQL Server:
SELECT 'Bob' [name], 50 [age] FOR JSON PATH
The expected output in SSMS is:
JSON_F52E2B61-18A1-11d1-B105-00805F49916B
-----------------------------------------
[{"name":"Bob","age":50}]
(1 row affected)
Calling this same query with :odbc module in ELIXIR gives different result each time:
{:selected, ['JSON_F52E2B61-18A1-11d1-B105-00805F49916B'],
[
[
<<0, 0, 80, 0, 114, 0, 111, 0, 75, 246, 34, 87, 97, 33, 0, 128, 32, 0, 70, 0, 105, 0, 108, 0, 74, 246, 33, 87, 92, 34, 0, 128, 105, 0, 99, 0, 114, 0, 111, 0, 73, 246, 32, 87, 102, 35, 0, 128, 32,
0>>
]

Is there a config setting required to get the correct results?
I use the following defaults:
defp _connect(conn_str) do
:odbc.connect(
to_charlist("Driver={ODBC Driver 17 for SQL Server};Server=" <> conn_str),
timeout: 30_000,
auto_commit: :on,
binary_strings: :on,
tuple_row: :off,
scrollable_cursors: :off,
trace_driver: :off,
extended_errors: :on
)
end
I would expect the result for invoking the same function multiple times would be the same?
